Cueva Anklis, also called Churchdoor, is a cave on the west coast just north of Ciutadella, with an Ariadne line running 80 metres in from the entrance. Maximum depth on the dive is 24.5 metres and it can be done from a boat or from the coast. From the back of the cave, looking out towards the blue, the play of light is what the site is dived for.

Also known as Churchdoor.

The dive

The site works from a boat or from the shore, and the dive is built around the cave rather than the rock outside it. Maximum depth is 24.5 metres. Inside, a permanent Ariadne line runs 80 metres in from the entrance, which is what makes the penetration repeatable rather than exploratory: you follow the line in and the same line back out instead of route-finding in the dark on the way home.

The payoff is at the far end. Looking back down the cave towards the blue, the entrance frames the light, and that play of light is what the site is dived for. Outside it, the rock and the shallows carry schools of damselfish, barracuda, white and gilthead seabream, thick-lipped grey mullet, ornate wrasse, moray eels, octopus, and both common and mottled groupers, so the exit is not a formality.

Know before you go

  • An 80 m penetration on a guideline is real overhead diving: gas reserved for the swim back out, a primary and a backup light, and training to match are not optional here.
