Cabo San Martin

Boats typically anchor over a sand-and-rock plain around 12m, and the route follows the cape wall from east to west, dropping gently toward 22m. The shallow tunnel crossing at about 3m comes next: a short swim-through with the exit visible the entire way, and light pouring through from both ends for a silhouette effect divers come back for. Cueva de la Virgen is the second act, a siphon-shaped chamber where careful buoyancy pays off, since stirring the floor ruins the visibility for the whole group. Two openings in the roof cast shafts of daylight onto a concrete Virgin statue at the back of the cave, the reason many divers book this site at all.

A wall dive, a genuinely photogenic tunnel, and a grotto with actual local folklore is an unusual combination for a site that never asks for advanced certification. The statue inside Cueva de la Virgen was reportedly placed by a Jávea diving couple who later held their wedding in the cave, giving the site a story that most reef dives simply don't have. What keeps it accessible despite the overhead environment is the light: two skylights above the grotto mean it never goes properly dark, so centres treat it as a Level 1 dive rather than technical cave territory. Locals often describe San Martín as one of the dives you have to do if you're diving Jávea at all.

A torch brings out the backlighting fully in both the tunnel and the grotto, though neither strictly needs one. Buoyancy is the one skill that matters here: the grotto's floor silts out fast, and once the group stirs it up, the light show is over for everyone behind you. Boats run this as a straightforward Level 1 dive, so it suits a diver's first look at an overhead environment as much as it suits someone who has done dozens. Boat time from Jávea port runs about 5 minutes, one of the shortest hops in the area, which keeps the surface interval short between the wall and the grotto.
