Why dive here
With 76+ marine species recorded in the area - including dolphins, octopuses, sea turtles, sperm whales and cuttlefish - Neptune’s Cave offers some of Canary Islands's richest cave diving. Water ranges 20-24°C, warmest August, September, October.
Neptune’s Cave in the Canaries is a good, straightforward dive, especially if you’re new to overhead environments. Dropping to 23m, it’s not a huge cave, but it offers a nice entry into cavern diving without feeling overwhelming. We’ve found the light plays well off the walls, revealing occasional crabs tucked into crevices and small schools of fish darting in and out. It’s a comfortable dive, usually with minimal current, making it a solid choice for beginners looking to try something a little different.
