The far northwest's epic, and a deliberate exception on this list: the Levada da Ribeira da Janela is not a classified PR trail, but it is one of the most ambitious tunnel walks on Madeira. The channel follows the right bank of the Ribeira da Janela — the longest river on the island — deep into a cliff-walled valley, the path hugging the inside wall above the gorge. Its centrepiece is a tunnel of more than 1,200 m, pitch-dark, dripping and partly flooded, with waterfalls spilling inside; in all there are roughly seven to nine tunnels. Crystalline pools punctuate the route, some deep enough to swim. Distances vary sharply with the chosen variant: about 11.5 km one-way along the levada, a long ~22.8 km full out-and-back, or roughly 16 km looped via the Vereda do Galhano. Edges are crumbly and exposed — for sure-footed hikers only.

🔦
Tunnels: 7–9 tunnels depending on the route; the longest exceeds 1,200 m (over 1 km), often with water and waterfalls dripping inside — a torch is essential. Bring a head-torch — some levada tunnels are long, low and pitch black.
