Dive Spot Guide•
Neptune’s Cave
Neptune’s Cave is a south Tenerife cavern dive with current.
South Tenerife cave route with a shallow start, volcanic rock, and current that can make the swim-through feel punchier than the depth suggests.
About Neptune’s Cave
Neptune’s Cave is a south Tenerife volcanic cavern route with a shallow start that opens into a larger swim-through. The profile mixes rocky ledges, sandy patches, and an overhead section, so it feels more like a route than a single feature. Current is the main variable, and the dive works best when the water is calm enough to keep the entrance and exit tidy. Expect trumpetfish, shrimp, grouper, stingrays, and the occasional angel shark.

Local Intel For Neptune’s Cave
Community notes to help plan your visit.
Scuba Diving
Best as a guided scuba dive with neutral buoyancy, a steady pace, and a conservative turn if the current at the mouth starts to build.
Freediving
The shallow approach may look tempting, but the cavern profile and current make scuba the better fit.
Snorkeling
Only the shallow approach makes sense for snorkeling, and only on very calm days; the cave line is a scuba route.
