El Caleton: swimming in Garachico’s volcanic pools
El Caletón is the set of natural pools carved into the lava that the 1706 eruption poured into the sea at Garachico, on the north coast of Tenerife. Ladders, walkways and a small solarium make them swimmable, but they are open to the Atlantic: on calm days the water is clear and sheltered, and on days with north swell the pools are washed by waves and are genuinely dangerous. Whether it is worth going depends almost entirely on the sea, not on the temperature.
Is it safe to swim today?
This is the question that decides the visit. With low north swell the pools behave like calm rock basins. With significant swell, water breaks over the lava and into the pools without warning, and local authorities close access. Never judge from the car park: watch a few sets from the walkway first, and respect any closure sign or flag.
What the pools are like
Several connected basins of black volcanic rock, of varying depth, with metal ladders, handrails and concrete platforms for sunbathing. There is no sand. Rock shoes are a sensible idea because the lava is sharp, and the water is noticeably cooler than in the south.
Getting there and parking
The pools sit at the entrance to Garachico, right beside the coastal road, roughly 30 minutes west of Puerto de la Cruz. There is free parking along the seafront and a larger area near the old town, both busy at weekends and in the middle of the day.
Combine it with Garachico
Garachico itself is one of the best preserved historic towns in Tenerife, with a walkable old centre, the San Miguel castle on the shore and plenty of restaurants. It works well as a half-day trip regardless of whether swimming is possible.
When to go
Mornings in summer, when the north coast is often clearer and the sea calmer, are the best window. Winter brings the heaviest Atlantic swell, so closures are more likely.
