About Cavernas
Cavernas in Sesimbra is a maze-like rocky dive with short swim-throughs, blind turns, and tight line-finding that rewards slow pacing and precise buoyancy. It suits experienced divers who want a more demanding route, with schooling fish, octopus, and cuttlefish in the gaps and a calm-day window that keeps the run more comfortable. Boat access from Sesimbra makes it a practical guided outing when conditions line up.
