The "Ravin de l'Enfer" lives up to its name poorly. It is a lush canyon, carved by millennia of erosion, that ends with a waterfall at the bottom of the canyon (spectacular after winter rains, sometimes reduced to a trickle in summer) falling into a natural pool surrounded by vertical cliffs. Morning light descends through the canyon's opening and illuminates the mist against the light — one of the most photographed sights on the island. It is one of Tenerife's hikes with strictly regulated access: 300 people per day maximum, mandatory reservation.
6.5 km round trip from the village of Adeje. The path runs along the bottom of the barranco between walls that rise 300 metres. The vegetation changes as you go: cacti and spurges at the entrance, ferns and mosses at the bottom. The elevation gain is moderate (~350m) and the climb is gradual. Only the last section before the waterfall requires attention — large rocks, narrow passages, and often wet. The return is by the same path. Allow 3 to 3.5 hours without hurrying. Your knees will work on the descent — take your time.
Book on barrancodelinfierno.es at least 3-4 days in advance. In high season (July-August, Christmas, Easter Week), minimum 1 week. Rates: check the daily price on barrancodelinfierno.es (often around €15 for non-resident adults in 2025-26; children 5-12 at reduced rate). Under 5s not admitted. The website assigns you a time slot — arrive 15 minutes before. Without a reservation, the guard at the entrance will turn you away without exception. The 8am and 8:30am slots are the best: fewer people, raking light in the canyon, and you pass the stragglers on the way down rather than having them behind you.
