Charco Azul, El Hierro, Canary Islands, Europe

Charco Azul is a natural swimming pool formed by volcanic rock on the northwest coast of El Hierro, one of the Canary Islands.

Visual Characteristics

The site features a series of interconnected natural pools carved into dark basaltic rock formations. The water within the pools is a deep turquoise to emerald green, contrasting with the black volcanic stone. A prominent natural arch or cave-like structure partially covers the main pool, providing a unique visual element. The surrounding cliffs are rugged and sparsely vegetated with resilient coastal flora.

Location & Access Logistics

Charco Azul is situated on the coastline below the village of El Golfo, within the municipality of Frontera. Access is primarily by vehicle via the HI-500 road, which descends from the main island road (HI-5) towards the coast. A designated parking area is available at the end of the access road. From the parking, a well-maintained wooden boardwalk and stairs lead down to the pools, approximately a 5-10 minute walk. Public transport options are limited; a local bus service (e.g., Line 08) may stop near the turn-off to the HI-500, requiring a significant walk.

Historical & Ecological Origin

Charco Azul is a geological formation resulting from ancient volcanic activity on El Hierro. The pools were created by the erosion of basaltic lava flows by the Atlantic Ocean over millennia. The distinctive arch and cave structures are formed by differential erosion of the volcanic rock, where softer layers have been worn away, leaving harder sections intact.

Key Highlights & Activities

Swimming and bathing in the natural pools are the primary activities. The calm, clear waters within the pools are suitable for snorkeling, allowing observation of the underwater rock formations. Photography of the unique volcanic landscape and the natural arch is a popular pursuit. Sunbathing on the surrounding rock ledges is also common.

Infrastructure & Amenities

The site has limited infrastructure. There are no public restrooms directly at the pools. Some wooden platforms and steps are installed for easier access. Natural shade is provided by the rock overhangs, but open areas are exposed to the sun. Cell phone signal (4G/5G) is generally available. There are no food vendors or shops directly at Charco Azul; the nearest facilities are in the nearby village of El Golfo or Las Puntas.

Best Time to Visit

The best time to visit is during periods of calm sea conditions, typically from late spring to early autumn (May to October), when the Atlantic swell is less pronounced. Visiting during low tide can offer easier access to certain areas of the pools and clearer water. Mid-morning or late afternoon provides optimal lighting for photography, minimizing harsh shadows within the cave structure.

Facts & Legends

The name "Charco Azul" translates to "Blue Pool," accurately describing the water's color. The site is part of the El Golfo Valley, a massive horseshoe-shaped depression formed by a catastrophic landslide approximately 15,000 years ago, which shaped much of El Hierro's current coastline.
