There’s no doubt about it, the Lost City trek in Colombia is an incredible adventure and one of South America’s top experiences. But if you’re worried about safety, you’re not alone. I recently completed the trek myself, and it was thrilling and challenging—but generally safe. The biggest risks are slipping on muddy trails or twisting an ankle.
Before heading out, I was cautious because Colombia has had a history of guerrilla activity. In this guide, I’ll break down the main safety concerns and share tips to stay safe on the trek.
Background: The Lost City Trek
The Lost City (Ciudad Perdida) is an ancient Tairona city in the Sierra Nevada mountains. The trek is fully guided, passes through indigenous villages, rivers, and jungle, and usually takes 4 days. For general details on the hike itself, check out my full Lost City trek guide [here].
Safety on the Trek: What You Need to Know
1. Violence: Colombia has experienced crime and guerrilla activity, but the Lost City trail has been safe for over 20 years. The trail was closed for 2 years after a 2003 kidnapping incident, but there have been no similar events since it reopened in 2005. Today, the army presence and the economic importance of tourism make the trek very safe.
2. Theft: Camps are dorm-style with 20–50 people per night. While theft is uncommon, it’s wise to secure valuables like phones and cash under your pillow or mattress. Trekking companies are not liable for lost items, so a little caution goes a long way.
3. Trail Conditions: The jungle terrain is rocky, muddy, and slippery, making ankle twists and falls the most common injuries. Steep stone steps near the Lost City require extra care. Avoid risky behavior like diving into shallow water. Otherwise, the trails are safe—there are no extreme drops or climbing hazards.
4. Food Safety: Food hygiene has improved, but a few hikers still report stomach issues. To be extra cautious, carry bottled water or purification tablets. All meals at camps are freshly prepared, and filtered water is provided.
5. Wildlife: The area is home to animals like jaguars, tapirs, monkeys, and toucans. Encounters with dangerous wildlife are rare. Shake out your boots each morning and stay alert, especially if venturing off-trail or outside camp at night.
6. Bugs: Mosquitoes are present, but not overwhelming. There’s a small risk of Yellow Fever; vaccination is optional but recommended if you want extra protection. Beds are fitted with mosquito nets, and daily use of bug spray is essential. Malaria is not an issue on this trek.
