Los Hervideros

A dramatic coastal formation on Lanzarote's western shore where lava flows from the 1730–1736 Timanfaya eruptions met the Atlantic Ocean, creating a jagged labyrinth of volcanic rock caves, blowholes, and chasms. When the Atlantic swell surges into the caves, water erupts upward through blowholes with explosive force — the name translates to "the boiling ones," describing the churning white water that appears to boil within the rock chambers. Wooden walkways and viewing platforms allow visitors to safely observe the spectacle. The best time to visit is during high tide or when the sea is rough, when the displays are most dramatic. Coastal walkways connect to nearby volcanic cliffs. Free entry. The adjacent Salinas de Janubio — historic salt pans dating from 1895 — produce sea salt using traditional methods and are worth visiting at sunset.
