description Islote de Hilario geothermal vents Overview
The Islote de Hilario geothermal vents are areas of intense subsurface heat within Timanfaya National Park on Lanzarote in Spain's Canary Islands. During demonstrations, water poured into pipes set in the ground is expelled as steam, while dry brush can ignite when placed in shallow openings. The heat is residual geothermal activity associated with the volcanic system beneath terrain shaped principally by Lanzarote's major eruptions of 1730-1736.
help Islote de Hilario geothermal vents FAQ
What demonstrations can you see at the Islote de Hilario geothermal vents in Timanfaya?
Guides pour water into a pipe sunk into the ground, and the extreme subsurface heat instantly ejects it as a tower of steam. In another demonstration, dry brush pushed a few centimeters into a shallow hole bursts into flames from the ground heat alone.
How hot is the ground at Islote de Hilario in Timanfaya National Park?
Measurements have recorded temperatures of several hundred degrees Celsius just a few meters below the surface at Islote de Hilario. The residual magmatic heat from the 1730–1736 Timanfaya eruptions remains the source of these extreme temperatures.
Can you drive your own car through the Islote de Hilario area of Timanfaya?
No, private vehicles are not permitted on the park's geothermal section. Visitors must take the designated El Diablo route on a park-operated coach bus, which passes Islote de Hilario and other volcanic features.
Where exactly is the Islote de Hilario located within Lanzarote?
Islote de Hilario is located inside Timanfaya National Park in the central-western part of Lanzarote, one of Spain's Canary Islands. It sits along the park's main visitor road known as the Ruta de los Volcanes.
