The Lost City is not lost and it is not a city; it is Teyuna, a Tairona town of stone terraces at 1,200 meters in the upper basin of the Buritaca river, on the northern face of the Sierra Nevada de Santa Marta, and the only way to stand on it is to walk there, two or three days in and the same back out, through heat, mud and river crossings, with a guide, because the trail is not marked and the institute that runs the site does not allow anyone on it alone. It is the best thing in the region for anyone who can do it, and the worst holiday of their life for the people who book it thinking it is a hike. This page is what we tell our own guests before they decide: what the site is, by the archaeologists who run it, how the four days actually go, how hard they are, what the trek costs and what the price buys, the month-by-month weather from IDEAM’s own stations on the mountain, the vaccine you need, the rules of the four peoples whose land you cross, whether it is safe, and the one date that decides everything this year: the archaeological park is closed for the whole of October 2026.
Where you sleep before and after is in our Santa Marta guide; the park on the coast that most people pair with the trek is in our Tayrona guide.
The short version
Four days, three nights in bunkhouse camps, walking five to ten kilometers a day on a trail that climbs and drops without mercy, in a climate the institute itself describes as warm, humid and very rainy, to reach a town built from the seventh century and abandoned at the end of the sixteenth, with more than two hundred structures across thirty-three hectares that the outside world did not know existed until the 1970s. You go with an authorized operator and a certified guide or you do not go. The park opens from 7 in the morning to 3 in the afternoon, the entrance is 75,000 pesos, and it is closed from October 1 to 31, 2026 by the institute’s own calendar, so no operator can take you in October. The driest months at the trailhead are January to March; September to November are the wettest, with October shut anyway. Get the yellow fever vaccine at least ten days before you fly, carry insurance that covers a helicopter, and do the Tayrona day after the trek, not before. Our four-day trek, private, with the entrance, the guide, pickup in Santa Marta and nine meals, is from 710 US dollars per person.
What Teyuna is, by the people who dug it out
The facts come from the institute that runs the site, the Instituto Colombiano de Antropología e Historia, and from its own visitor guide, written by Santiago Giraldo and Luisa Fernanda Herrera, one of the two archaeologists whose expeditions from 1973 reached it. Teyuna sits at 1,200 meters in the upper Buritaca basin, on the northern face of a mountain range that covers about 16,500 square kilometers and rises from the Caribbean to 5,775 meters at Pico Cristóbal Colón, the highest coastal range on earth by the city’s own description. The Tairona built it from the seventh century AD and abandoned it toward the end of the sixteenth, after the Spanish arrived on the coast; it is one of about two hundred ancient settlements the institute has identified in the range, and the one the trek reaches. What survives is the stonework: more than two hundred structures across thirty-three hectares, the circular terraces that held the houses, the ceremonial platforms, the staircases and the paths that connect the sectors, with the forest grown back over everything the Tairona built in wood and thatch. The discovery was, in the institute’s own words, accidental and unfortunate: looters found it, the archaeologists followed, and the institute has run the research, the conservation and the park since 1976, in phases that took a decade. The 1972 date on many tour pages is the year the looting is said to have begun; the institute dates its own arrival to 1976, and the archaeological park is inside the Kogui-Malayo-Arhuaco indigenous reserve, on land that the four peoples of the Sierra, the Kogui, the Wiwa, the Arhuaco and the Kankuamo, consider sacred and manage together with the institute.
The 2026 calendar: October is closed
Every year the site closes for a period so the indigenous authorities can do their own work in it, by resolution of the institute. Up to 2024 the closure fell in September, for about two weeks, on dates that moved from year to year; for 2026 the institute’s published calendar for the second half of the year closes the Parque Arqueológico Nacional Teyuna from the first to the thirty-first of October. During a closure only the indigenous authorities, the institute’s staff, the park officials and the security forces may enter, and no operator can negotiate around it, so if your dates are in October, the trek is not on the table and anyone who sells you one is selling you a walk to a locked gate. On open days the park receives visitors from 7 in the morning to 3 in the afternoon, and the institute asks that you walk it only within those hours and when visibility allows, which matters on a mountain where the cloud comes in most afternoons. The single entrance fee is 75,000 pesos, and the institute says the money goes to the conservation and maintenance of its parks. The institute also warns that it can close the park at short notice for natural risk, access, maintenance or public order, which is why we check with it the week before every departure rather than the month before.
How the four days go
Day one. We pick you up at your hotel in Santa Marta in the morning and drive east along the Troncal del Caribe, the coast road toward Tayrona and Palomino; where the road to the site leaves the highway, the vehicle becomes a four-by-four for one to two hours of unpaved track up to Machete Pelao, the hamlet most maps call El Mamey, where the trail begins. Then the first afternoon of walking: the trail climbs immediately and steeply, in the heat of the day, and this first stretch is where most people find out what they signed up for. The first camp is on the river.
Day two. The long day. You walk along and above the Buritaca, crossing it where the trail does, through the forest and past the first indigenous settlements, with the climbs and descents that give the trek its reputation; the institute’s own description is five to ten kilometers a day, and the kilometers are vertical. The second camp is the last one before the stairs.
Day three. You leave at first light for the final ascent, which the institute times at forty minutes to an hour from the camp below: the stone staircase, about 1,200 steps that every guide will count for you, climbs from the river to the first terraces. You have the morning on the site, walked the way the institute lays it out, the great central terrace, the Piedras sector, down to Mahecha and around the peripheral path to the northern sector, La Gallera, with the guide explaining what the stones were. Then you walk back down the stairs and retrace the trail to a camp on the way out.
Day four. The walk out to El Mamey, the four-by-four down to the highway and the drive back to Santa Marta, where you will want a shower more than you have ever wanted anything. Some operators run the same route in five days, splitting the long stretches; four is the standard and it is what we sell, and if you want the extra day, tell us and we will price it.
How hard it is, honestly
The distances are not the problem. The problem is that the trail goes up and down the flanks of a wet mountain at the latitude of the equator, so you are climbing in the heat of the coast, where IDEAM’s airport station averages a daily high of 33 degrees, with the air holding more water than your shirt can, on a surface that is mud after every rain, and rain comes most afternoons. IDEAM’s Alto de Mira station, at 1,080 meters in the municipality of Santa Marta, close to the site’s own altitude, records an average relative humidity of 93 percent across the year and rain on 235 days of it; the institute puts the nights at 18 to 22 degrees, which is the first time you will be cold. The river crossings are real crossings, knee to thigh deep after rain, and the stairs to the site are steep, uneven and slick. You need to be fit in the ordinary sense, able to walk uphill for hours with a daypack and get up the next day and do it again, and you need to be honest with yourself about your knees, your heart and your heat tolerance, because there is no road out; the way back from the second camp is the way you came. Age matters less than habit: a walker of sixty who hikes at home will enjoy it more than a twenty-year-old who has not climbed a hill in years. The guide sets the pace and will slow it, but the trail does not get shorter. Ask us before you book for a child.
When to go: the weather by IDEAM’s numbers
The Sierra makes its own weather and the trailhead is the wettest part of the Santa Marta coast. The table is IDEAM’s 1991 to 2020 normal for its Buritaca station, at 30 meters on the river you follow, in millimeters of rain per month and the average number of days with rain, 1,909 millimeters on 75 days across the year; the site itself, a thousand meters higher, gets more of both.
| Month | Rain | Days |
|---|---|---|
| January | 40 | 2 |
| February | 34 | 2 |
| March | 62 | 3 |
| April | 90 | 5 |
| May | 152 | 7 |
| June | 115 | 5 |
| July | 93 | 4 |
| August | 196 | 8 |
| September | 231 | 10 |
| October | 350 | 12 |
| November | 377 | 12 |
| December | 168 | 6 |
Read it as three seasons. December to March is the dry season, with January and February almost rainless at the trailhead, low rivers, firm trail and the clearest mornings on the terraces; it is also the season everyone else chooses, so book ahead. April to July is the middle: real rain from May, a drier lull in June and July that Colombians call the veranillo, with the trail wet but the crossings manageable. August to November is the wet season, and it is not a marketing distinction: October and November each bring nine times January’s rain, the rivers rise, the crossings get serious, and the site is closed for all of October in any case. If you can choose, choose January to March; if you cannot, June and July are the second-best window; if your dates are September or November, come with the right boots, a dry bag for everything, and the understanding that the guide may hold the group at a river until it drops. Tour pages that call August a dry month are wrong by IDEAM’s figures; August is the start of the wet season here, not the end of the dry.
What to pack, from the institute’s list and ours
The institute’s own advice is short and correct: waterproof bags for everything, a poncho or rain jacket, comfortable boots that are not leather, plasters for blisters, clothing that is not cotton, sunscreen and a hat. We add: a second pair of shoes for the river crossings and the camps, sandals or trail runners you do not mind soaking; two sets of walking clothes and one dry set that never leaves its bag; a headlamp, because the stairs are climbed before sunrise and electricity at the camps is limited; repellent with DEET or picaridin for dusk at the camps; a small towel; toilet paper; a power bank, because there is no signal on the mountain from the first camp on, the institute says so and it is true, so your phone is a camera and nothing else; cash in small pesos for drinks at the camps; and a light sleeping bag liner or sheet for the bunks in the dry months, more in the wet ones when the nights are at 18. Everything you carry in comes out with you: the institute is explicit that the park has no rubbish collection and that every piece of waste returns to Santa Marta in your pack. Leave the drone at home, leave the swimsuit for the rivers, not the site, and leave anything you cannot afford to get wet, lost or broken.
Health: the vaccine, the mosquitoes and the water
Yellow fever first, because it is the thing people find out about too late. The Sierra Nevada de Santa Marta has been on the Ministry of Health’s list of yellow fever risk zones for years, alongside the Amazon and the Orinoco plains, and since April 2025 the ministry has had a national sanitary emergency in force for the disease under which travelers to the municipalities it classes as high or very high risk must be vaccinated at least ten days before travel; the classification is updated on the ministry’s site and the vaccine is free at public vaccination points in Colombia. Do not gamble on the classification of the week: get the shot at home or in Bogotá at least ten days before the trek and keep the certificate with your passport. Dengue is present on the whole coast and the camps are on rivers, so the repellent is for dusk every day, and long sleeves at the camps cost nothing. Drink only the water the guide gives you or treats; the camps supply it. Blisters are the injury that actually ends treks here, which is why the institute’s list starts with plasters and why the boots must be broken in before you land. Carry travel insurance that covers evacuation from a place with no road, and tell us before you book about any heart, knee or respiratory condition, not because we will refuse you but because the guide needs to know.
The four peoples and the rules of the mountain
You are a guest on land that belongs, by Colombian law and by their own account, to the Kogui, the Wiwa, the Arhuaco and the Kankuamo, whose reserves cover most of the mountain’s protected land and whose territory is bounded by the Línea Negra recognized in Decreto 1500 de 2018. The archaeological park is inside the Kogui-Malayo-Arhuaco reserve, and the annual closure exists because the peoples use the site for their own work. The institute’s rules for visitors are the ones we hold our guests to: do not damage or mark anything, natural or built; do not enter the houses of the communities you pass, and do not photograph people without asking and being told yes; stay on the trail and on the marked sectors of the site; carry every piece of your rubbish out. The guides, some of them from the indigenous communities along the route, will tell you what the Kogui villages are and why you walk around them rather than through; listen, because the trek is a walk through someone’s home, and the terraces at the top are their sacred ground before they are your photograph.
Is the Lost City trek safe?
By the two advisories we read for every page, yes. The British Foreign Office’s Colombia advice, updated on September 3, 2026, and the United States’ advisory, at Level 3 for the whole country since April 2025, both name the parts of Colombia they warn against, and neither names Magdalena, Santa Marta or the Sierra Nevada. The history that people half remember is real: in September 2003 eight foreign hikers were kidnapped by guerrillas on the way to Ciudad Perdida, in the worst episode the trail has known. The trail today runs under the institute’s rules: authorized operators only, a certified guide with every group, and no one on the trail alone. The armed groups that still exist in the Sierra are described plainly, from the ombudsman’s own document, in our guide to whether Santa Marta is safe; none of it touches the trail as it is run today. The risks that actually reach trekkers are the ordinary ones of a wet mountain: a turned ankle on the stairs, a river that rose overnight, heat exhaustion on the first afternoon, a blister that became an infection. The guide’s job is to see all four coming, and ours is to send you with a guide who has walked the trail more times than you have walked to work.
What it costs and what the price buys
Our four-day trek is from 710 US dollars per person, private, and the price includes the pickup and drop-off at your hotel in Santa Marta, the entrance to the park, the local guide for all four days, three breakfasts, three lunches and three dinners at the camps, and all-risk insurance. It does not include drinks and snacks bought at the camps, tips for the guide and the camp families, or your own gear. The entrance, 75,000 pesos by the institute’s tariff, is in the price and paid by us. The camps are the same for everyone on the mountain, whichever operator you book with: bunks or hammocks under mosquito nets, cold showers, and food cooked by the families who run them; what differs between operators is the guide, the group size, the pace and what happens when something goes wrong, which is what you are paying for.
Before and after: how to build the week around it
Fly into Santa Marta and sleep there the night before, in the old center or El Rodadero, so the pickup is short and you start rested; the airport and the ride in are in our Santa Marta airport guide. Do the trek first and the coast second: four days of walking followed by a Tayrona day or a beach day at Palomino is a holiday, and the other way around is a sunburnt person starting a trek. After the trek, a night in Santa Marta, then Tayrona, which closes three times a year on its own calendar, or Minca for a cool night in the foothills; both are in the guides linked at the top and in our Minca guide. If Cartagena is on the itinerary, put it at the end, four hours west by road, and take the sea days there. Six nights on the coast is the shortest version of this that does not feel rushed: one before, three on the trek, two after.
What we do differently, and what we cannot promise
We run the trek with one of the operators authorized for the route, with a guide who lives on this coast, a private group, hotel pickup and all-risk insurance, and we check the park’s calendar and the river with the operator the week before you go, not the month before. We tell you the October closure and the yellow fever rule before you pay rather than after. What we cannot promise is dry weather, a dry trail or a river that stays low, because the Sierra decides those, and we cannot promise that the institute will not close the park at short notice for the reasons it lists; what we can promise is that if it does, you will hear it from us before you leave Santa Marta, with a plan for the days instead.
Questions travelers ask
How long is the Lost City trek?
Four days and three nights as we run it, two or three walking days in and the same out by the institute’s description, at five to ten kilometers a day, with the morning of the third day on the site. Five-day versions split the long stretches.
Is the Lost City closed in 2026?
From October 1 to 31, 2026, by the institute’s published calendar for the second half of the year. The rest of the year it opens daily from 7 in the morning to 3 in the afternoon, subject to short-notice closures for weather, access, maintenance or public order.
How much does the Lost City trek cost?
Our private four-day trek is from 710 US dollars per person with the entrance, the guide, hotel pickup in Santa Marta, nine meals and insurance included. The park’s entrance fee alone is 75,000 pesos.
Can you do the Lost City trek without a guide?
No. The institute requires a certified guide and an authorized operator, because the trail is unmarked and dangerous alone, and the indigenous authorities and the park officials enforce it.
What is the best month for the Lost City trek?
January to March, the dry season at the trailhead by IDEAM’s figures, with June and July as the second window. September and November are the wettest open months, and October is closed.
Do I need the yellow fever vaccine for the Lost City?
Yes. The Sierra Nevada is on the Ministry of Health’s yellow fever risk list and the ministry’s 2025 emergency rules require vaccination at least ten days before travel to high-risk municipalities. Get it before you fly and carry the certificate.
How hard is the Lost City trek?
Hard, for the heat and the humidity more than the distance: steep climbs and descents on mud, river crossings, 93 percent humidity at the site’s altitude by IDEAM, and a 1,200-step staircase before breakfast on day three. Fit walkers with broken-in boots do it; nobody should do it as their first hike.
