Caño Cristalers is an eco-destination, because of this it is important to listen to the instructions of the (local) guide. The water plants are very sensitive and we will only cross the Caño or swim at places indicated by the guide. The use of sunblock or mosquite repellent is forbidden in the caño. So bring proper clothes to protect yourself from the sun and mosquitos.
For this area you need to have the yellow fever vaccination and be able to proof this, so bring your vaccination card.
