Ribeira do Inferno

verified Ungraded High flood risk Sao Vicente, Madeira

Madeira's deep one: 27 rappels and over 1,800 feet of loss in basalt. A V-commitment day, with jump opportunities mixed into the rappel sequence.

Aka Ribeira Pau do Inferno and Paúl de Inferno. Recent (2024) trip reports describe it as the island's most impressive descent for groups who can manage the duration and commitment. Pair only with very settled weather; the V grade means no easy bailouts.
