Depart Funchal and journey to the start of your walk, where you will follow the routes of the "levada" irrigation system developed in the 16th century by Madeira's first settlers. Descend from the plateau of Paul da Serra to the Rabaçal guesthouse and walk to the waterfall of the Levada do Risco. Continue towards the Levada das 25 Fontes, dominated by moorland at its highest point. Walk until you reach a small lagoon at the bottom of an enormous cliff, and marvel at the sight of 25 natural springs cascading into the lake. Return along a different path, passing through a tunnel that carries water to the south of the island. Admire a wide variety of endemic flora and fauna along the way.
