The Avenc dels Geòlegs, located in Vallirana (Baix Llobregat), is the ideal cave for anyone taking their first steps into the world of caving and speleology. The approach to the 10 x 6 metre entrance is only 10 minutes long, and the full activity lasts 3 to 4 hours. The pothole features a 23-metre abseil and a total passage length of 65 metres. Throughout the route you'll discover incredible karst formations in a spectacular setting; one particularly curious feature is that natural light filters in well enough that headtorches aren't always necessary. Different lines can be taken depending on the group's level. A perfect first underground adventure for anyone curious about exploring the world beneath their feet. Duration: 3–4 hours. Difficulty: Introductory.
