Malaria tablets are not necessary for the Lost City trek. Whilst there are plenty of mosquitoes and other insects on the trail, they do not carry malaria. For comfort we recommend packing insect repellent that contains DEET.
You will need a yellow fever vaccination for Colombia, although there haven’t been reports of yellow fever in the region around La Ciudad Perdida.
Whilst hiking, you may also encounter snakes and spiders. Exercise common sense by giving them a wide berth and you will be fine.
The most likely injury to occur is slipping on the track and twisting your ankle or hurting your knee. Just take things slowly if you’re unsure.
Another thing to watch out for is sunburn and heatstroke. Both of these can be avoided by applying sun block, wearing suitable clothing and staying hydrated by drinking water regularly.
Treated water is provided by the guides so you can fill your water bottle up in the mornings and evenings.
It’s a good idea to take some alcohol based hand wash that doesn’t require water. Using it will reduce the risk of you getting sick.
In terms of physical security, the Colombian Army regularly patrols the trail and ruins. The first and only kidnapping occurred in 2003 and ended with the safe release of those taken. The Colombian government has made security a priority across the country especially in regards to tourism.
