Why swim at El Caletón in Garachico?
Garachico was once Tenerife's most prosperous trading harbour, shipping Malmsey wine across Europe. In 1706, the Trevejo volcano erupted, sending two massive streams of molten basalt into the bay and burying much of the port.
Where the lava hit the cold ocean, it created El Caletón: a labyrinth of protected saltwater basins, channels and natural platforms. Every tide washes through with fresh Atlantic water, offering a serene swimming spot surrounded by black rock and colonial churches.
What to expect
Heritage walk to the shore
Stroll through cobbled plazas and past whitewashed convents before walking onto the smooth black lava paths of the pool complex.
Swimming in volcanic basins
Choose from open, deep basins for swimming or calmer shallow tidal hollows equipped with access steps and handrails.
Clear ocean snorkelling
Peer underwater to see colourful Canary damselfish, wrasses and anemones thriving on the submerged basalt shelves.
Plan your experience
When to go
Check marine forecasts and tide tables. Low to mid tide provides the calmest swimming. Heavy winter ocean swells can result in temporary pool closures for safety.
Getting there
Drive the TF-42 coastal highway from Icod de los Vinos. Public parking is available near the seafront promenade and adjacent to the former port.
Booking & permits
El Caletón is free and open to the public. There is seasonal lifeguard surveillance during summer months. No tickets or permits needed.
What to bring
- Water shoes or reef booties (basalt rock can be rough underfoot)
- Snorkel and mask
- Sun protection and beach towel
Before you go
- Always observe the beach safety flags: red flag means swimming is prohibited due to high waves.
- Pair your swim with fresh grilled fish and papas arrugadas at a seafront restaurant.
