The trail of the great tunnel. It leaves the Caldeira leisure area, known as the "Garagem", on Estrada Dr. Roberto Monteiro (the official list writes "Roberto Ornelas") and reaches Casa do Rabaçal, the meeting point of all the Rabaçal trails: 2.3 km, about 45 minutes, between 988 and 1,055 m. The first 800 m follow a forest track to the Túnel do Cavalo, also called Furado Novo or Furado das 25 Fontes. Bored from 1863 to 1877 and about 800 m long, it carries the water of the Ribeira dos Cedros and the 25 Fontes under the mountain, in the Levada Nova do Rabaçal, to the municipality of Calheta: hydroelectric plant, drinking water and irrigation. A head torch is essential; the tunnel is high and easy to walk. At the exit you follow the Levada das 25 Fontes to the staircase on the right that climbs to Casa do Rabaçal; carrying on along the levada takes you to the Lagoa das 25 Fontes. At Rabaçal, the reception centre tells the story of how Madeira's levadas were built.
