Las Calderas is a ship from the beginning of the 20th century on the Atlantic side of the island, named for the three boilers still recognisable in the wreckage. The dive runs 8–20 m, shallow enough that YellowSub takes beginners on it as well as experienced divers. Morays, congers and groupers live in the holes in the structure, with lobster and spider crabs on the plating.
Where it is and how deep

The dive
The anchorage is tied to the wreck itself, so the descent puts you straight onto the structure. From there the route works along the deck and under the hull, with the three boilers — the reason for the name — the clearest surviving feature on it. León Marino gives the depth as 8–18 m and YellowSub 5–20 m, which makes this the shallowest of the wrecks Tarifa's centres dive.
The small holes in the plating are where the life is: morays and conger eels, groupers, octopus, nudibranchs, electric rays, snapper and dentex, with eagle rays and sand eels turning up now and then. Lobster, spider crabs and gorgonian growth cover the outside of the wreck. Nothing here asks for penetration — the dive is worked from outside the hull and under it, not inside.
The wreck
- Vessel
- Unidentified ship, known as Las Calderas
- Type
- Early 20th-century ship, three boilers surviving
- Cause
- Not recorded by the Tarifa operators or the site catalogue
- Lies
- On the bottom on the island's Atlantic side, deck and three boilers exposed, the hull clear enough to swim beneath
The ship's own name is gone. Scubago dates the vessel to the beginning of the 20th century, and both Tarifa centres call the site only Las Calderas, the boilers, after the three that still stand among the remains. No source records the ship's identity, its flag, what it was carrying or how it came to be on the bottom off the island's Atlantic side.
