Baja de Los Realejos

A basaltic peak rises almost straight up from the seabed, breaking into distinct steps as it climbs, with large boulders scattered around its base forming corridors and small caves. Toward the south, the main summit connects to a second formation shaped like a mushroom. Depth here spans an unusually wide range for a single dive: the base sits somewhere between 45 and 70 metres, while the shallowest point of the peak comes up to 9-15 metres, so the profile depends entirely on how deep the group goes. Large schools of fish work the peak, amberjacks and barracuda moving through open water above the rock, while gorgonians, sponges and small invertebrates cover the walls lower down. Occasional pelagics, tuna among them, pass through without warning.

Every other advanced dive on this stretch of Tenerife's north coast is a sheltered tunnel or chamber cut into the cliff. This one isn't. It's a genuine open-water seamount, exposed to current and set well offshore, and that combination makes it a serious destination rather than a scenic stop on the way to somewhere else. It sits in Los Realejos municipality, its own destination rather than an extension of the tighter Puerto de la Cruz cluster a short distance east. Divers who want caves, arches, tunnels and abysses inside one profile, rather than one signature feature, come here for the variety as much as the current.

Current is the deciding factor on this dive, consistently strong enough that it's the main reason this isn't a beginner site. A torch helps for the cave sections around the base of the peak. Visibility runs wide across the seasons, from 15-20 metres in winter up to 40-50 metres in summer, with autumn often flagged as the best combination of clear water and comfortable temperature. This reads as a dive for divers who already have some local Tenerife experience behind them, rather than a first Canary Islands dive. Access is boat-only.
