Your island guide to the best beaches, events, nature, life & culture
On the southwest coast of Tenerife, the El Marquéz area of Costa Adeje offers a raw volcanic shoreline shaped into natural tidal pools. It’s a favourite spot for sea swims on calm days, with metal ladders helping you enter and exit the Atlantic safely. Below you’ll find a photo guide showing the layout, access points and nearby landmarks such as Roca Negra.
This overview shows the flat, petrified lava platforms that frame the shore. At mid and low tide, shallow basins form among the rocks, creating calm windows of water protected from the ocean swell.
From this vantage point you can see how the rock ledges step down to the water. Always check wave conditions before entering; the scene changes quickly with wind and tide.
The pools fill naturally with each surge, leaving glassy pockets of seawater that are perfect for a cool dip when the swell is gentle. Look for the smooth, man-made ramps that make the approach easier.
Several ramps like this one guide you to stable entry points. Footwear with grip is highly recommended—the lava can be slick with algae and spray.
The metal ladders are the safest way to enter and exit. Use them when waves are present, and avoid jumping—depth changes with the tide and some rocks sit just below the surface.
Looking back from the rocks you see Costa Adeje’s hotel zone and palm-lined promenades. Despite the urban setting, this corner keeps a wild, natural character compared with the big sandy beaches nearby.
The Roca Negra frontage sits just above the cliffs. From here you can watch the swell rolling in over layered lava and see how the coastline has been carved by centuries of waves.
The official sign at the path lists common-sense rules: mind the waves, avoid bringing glass, and respect the natural setting. Check conditions and never swim alone—lifeguards are not usually present.
El Marquéz in Costa Adeje is best on calm mornings when the tide is midway and the pools are replenished. Bring reef-safe sunscreen, water shoes and a towel, and allow time to explore the coves carved into the lava shelves. With ladders, ramps and a dramatic volcanic backdrop, this is one of the most atmospheric places for a natural sea swim on Tenerife’s sunny southwest coast.
