What Is the Lost City Trek?
Ciudad Perdida, meaning “Lost City,” is an ancient archaeological site hidden within the Sierra Nevada de Santa Marta.
The site is also known as Teyuna and is associated with the ancient Tayrona civilization. Colombia’s tourism authority says the settlement was built around 700 AD, while other official tourism material places major development around the 7th–8th centuries.
The archaeological complex contains circular terraces, stone paths, stairways, and water-management channels.
The surrounding Sierra Nevada remains culturally important to the Kogui, Arhuaco, Wiwa and Kankuamo Indigenous peoples, making the trek both an outdoor adventure and a cultural journey.
Lost City Trek Route
The classic trek begins near El Mamey, reached by road from Santa Marta.
A simplified route looks like:
Santa Marta → El Mamey → Jungle Camps → Buritaca River Area → Ciudad Perdida → Return to El Mamey → Santa Marta
The exact overnight stops vary by tour operator and itinerary.
Day 1: El Mamey to the First Camp
The adventure starts with transportation from Santa Marta toward El Mamey.
From the trailhead, the route immediately begins climbing through tropical vegetation. Expect heat, humidity and uneven terrain.
The first day is shorter than some later stages, but it introduces the conditions you’ll experience throughout the trek.
Day 2: Deeper Into the Sierra Nevada
The second day generally takes you deeper into the jungle, with steeper sections, river crossings and changing terrain.
The combination of humidity and repeated ascents can make the trail feel harder than the distance suggests.
Take advantage of designated swimming areas or rivers only where your guide confirms they are safe.
Day 3: The Final Approach to Ciudad Perdida
As you get closer to Teyuna, the trail becomes increasingly dramatic.
One of the defining moments comes when you reach the long stone staircase leading toward the archaeological site.
Colombia Travel describes the final approach as involving more than 1,200 stone steps.
Day 4: Ciudad Perdida & Return Journey
Reaching Ciudad Perdida is the main highlight of the trek.
At the archaeological site, you’ll see stone terraces, circular platforms, stairways and pathways surrounded by dense greenery.
Take time to appreciate the architecture rather than treating the site simply as a photo stop. Teyuna is a culturally significant place and remains connected to the Indigenous communities of the Sierra Nevada.
After exploring the site with your guide, you’ll begin the return journey.
Days 5–6: Return to El Mamey
Longer itineraries spread the return journey across additional days.
The exact schedule depends on the operator, group pace and route conditions. This is one reason why 4-day, 5-day and 6-day Lost City tours can all exist without representing completely different destinations.
Why the Lost City Trek Is So Special
The appeal of the trek isn’t only the archaeological destination.
Along the route, you experience:
- Tropical rainforest
- Mountain scenery
- Rivers and streams
- Waterfalls
- Wildlife and birds
- Indigenous cultural landscapes
- Ancient stone pathways
- Remote jungle camps
The Sierra Nevada de Santa Marta is also recognized as a UNESCO Biosphere Reserve and World Heritage area, and it is home to several Indigenous peoples.
Lost City Trek Difficulty
Difficulty: Moderate to strenuous
The trail isn’t extremely high altitude compared with famous Himalayan treks, but the physical challenge comes from the combination of:
- Long walking days
- Repeated climbs and descents
- High humidity
- Tropical heat
- Mud during wet conditions
- River crossings
- Uneven stone trails
- Limited modern facilities
You don’t need technical climbing skills, but a reasonable level of hiking fitness is important.
If you regularly hike long distances and can comfortably manage several consecutive active days, preparation will be much easier.
Do You Need a Guide for the Lost City Trek?
Yes.
Access to Ciudad Perdida is regulated, and National Parks states that visitors must be accompanied by a guide because of the area’s geographic, natural and cultural conditions.
Colombia Travel also recommends using authorized companies that manage the route.
This isn’t a trek where independent navigation should be your plan. Book through an authorized operator and follow your guide’s instructions, particularly around Indigenous areas, river crossings and archaeological zones.
Best Time for the Lost City Trek
The Sierra Nevada is tropical, so conditions can be hot and humid.
Instead of choosing dates solely by temperature, consider:
- Rainfall
- Trail conditions
- River levels
- Heat and humidity
- Your tolerance for wet hiking
Conditions can change quickly, and the route may become more difficult after heavy rain.
Before booking, check the latest conditions and operating information with your authorized trek operator.

Keep your backpack light. Tour operators typically arrange meals and sleeping facilities, so carrying unnecessary equipment only makes the climbs harder.
Essential Packing List

- Quick-drying shirts and trousers
- Lightweight rain jacket or poncho
- Insect repellent
- Sunscreen
- Reusable water bottle
- Headlamp
- Small quick-dry towel
- Swimwear

Is the Lost City Trek Worth It?
If you’re looking for a hike that combines jungle adventure, ancient history and cultural discovery, the Lost City Trek offers a very different experience from a conventional summit hike.
The journey is not about reaching the highest peak. Instead, the reward is gradually discovering an ancient archaeological complex hidden deep within the Sierra Nevada.
The heat, humidity, steep sections and basic camping conditions make it a real trek—but that’s also what makes reaching Teyuna feel meaningful.
