Abismo Guy Collet
The Abismo Guy Collet (SP-090) is the deepest cave in South America, and the deepest in the world that is formed in quartzite. Located in a tepui in northern Brazil near the border with Venezuela, this cave was first explored by cavers in 2006 to a depth of 671 meters.
Baredine Cave
The sightseeing lasts 40 minutes, visitors descend along a 300m long pathway up to 60m below the ground and an underground lake and visit 5 beautifully decorated chambers.
An interesting detail of this adventurous trip is also the encounter with the underground world of animals: visitors will see the cave olm (Proteus anguinus Laurenti), endemic in this dinaric karst region- an animal that can be found only in this karst area.
In one of the chambers you will pass along a 4m wide passage that leads 66m vertically down reaching the deepest point of the cave at 132m.
