Castelo - Algarve & Berlengas

Castelo sits at a shallow 9m, perfect for those just getting comfortable underwater. It’s mostly rock formations and sand, where we often spot octopus tucked into crevices and schools of bream cruising by. Visibility can be a bit variable, but on a good day, it’s a relaxed drift. This is a solid spot for beginners or anyone looking for an easy, no-stress dive.
