Las Grietas, Natural canyon in Tías, Spain
Las Grietas is a natural canyon formed by deep cracks in volcanic rock, creating narrow passages between tall cliff walls. Water collects in pools at the base, filling gaps and hollows throughout the rocky landscape.
The canyon took shape through volcanic eruptions in the 18th century that reshaped the entire landscape of Lanzarote Island. The cracks and fissures visible today are direct results of these ancient forces.
The name Las Grietas refers to the cracks and fissures that define the landscape, visible as you walk between the rock formations. The narrow passages and cool recesses serve visitors as natural refuge from the sun.
Check with local authorities before visiting, as access can be restricted for safety and environmental reasons. Wear sturdy shoes and move carefully through tight spaces between the rocks.
The water pools in the canyon contain a blend of saltwater and freshwater, creating unusual conditions for marine organisms. This rare mixing of two water types draws visitors curious about which species thrive in such special settings.
