The "Ravine of Hell" lives up to its name in all the wrong ways. It's a lush canyon, carved by millennia of erosion, ending in a 200-meter waterfall that plunges into a natural pool surrounded by vertical cliffs. Morning light descends through the canyon's opening and illuminates the mist in backlighting — one of the most photographed sights on the island. It's also the only hike in Tenerife that requires a reservation: 300 people per day, not one more.
6.5 km round trip from the village of Adeje. The path runs along the bottom of the barranco between walls that rise 300 meters high. The vegetation changes as you go: cacti and euphorbias at the entrance, ferns and mosses at the bottom. The elevation gain is moderate (~350m) and the climb is gradual. Only the final section before the waterfall demands attention — large rocks, narrow passages, and often wet. The return follows the same path. Allow 3 to 3.5 hours without rushing. Your knees will feel it on the way down — take your time.
Reserve on barrancodelinfierno.es at least 3-4 days in advance. During peak season (July-August, Christmas, Easter Week), book at least 1 week ahead. Price: €8.50/adult, €3.50/child. The site assigns you a time slot — arrive 15 minutes early. Without a reservation, the guard at the entrance will turn you away without exception. The 8:00 AM and 8:30 AM slots are best: fewer crowds, grazing light in the canyon, and you'll pass stragglers on your way down rather than having them behind you.
