The Lost City trek is a bucket list hike in Colombia where you can see the ruins of the Ciudad Perdida, an ancient city built by the Tairona people more than 1,000 years ago.
It’s a guided jungle trek that normally takes 4 days, and includes food and lodging in camps along the route. There’s plenty of challenge, but the local guides are very kind, helpful, and knowledgeable.
I did the Lost City hike recently and it was a great experience. We had a fun group and we went far into the Sierra Nevada mountains, visited indigenous villages, crossed rivers, swam every day, and hiked till our legs hurt.
