An adventurous hike through the National Park! Inside the about 9 km wide gigantic crater we walk downhill, starting at 1,000 m above sea level through forests of pinetrees, endemic in the Canary Islands Archipelago. We reach the Taburiente River - the only stream of the Canary Islands which has water all year round. Hiking through the land Acero with the holy rock of the aboriginal people called Idafe, we reach the Barranco de Los Angustias ravine which surprises us with its geological curiosities created by submarine volcanic eruptions. Route: approx. 16 km, time: approx. 6.5 hours.
