How to get there
Follow the Regional Road towards the Caldeirão (about 8 kilometres), until you find the viewpoint.
Appropriate footwear for walking, waterproof jacket, hat, sunscreen and water.
This circular trail is inserted in the Protected Area for the Management of Habitats or Species of Costa e Caldeirão do Corvo and allows to access a collapse crater, at the top of the central volcano and one of the main geosites of the island. It progresses in an altitude between 400 and 560 meters, being advisable to do it in days of good weather and visibility. Along the trail, it is common the presence of bovine, equine and goat cattle that should not be disturbed.
Begin the trail near the viewpoint of Caldeirão and enjoy the view towards the interior of the crater where, according to local culture, the lake and the few volcanic cones are a representation of the nine islands of the Azores. The road unwinds into the interior of the crater between flora dominated by Sphagnum sp. (musgão). Arriving at a big rock, choose the road on the right to go around the crater (counter clockwise). At this stage of the trail, we advise increased attention since the trail marks are smaller in order to resist the animals.
The interior of the crater is dominated by a system of wetlands and by two lagoons, nourished by the rain and by the water accumulated on the thick tuffs of peat moss (peat bogs) existing on the slopes facing north. It should be noted that the biggest and oldest peat bogs of the country are present on Corvo and Flores islands. Along the year the lagoon level changes and can go up as far as the trail level. Therefore choose the safest way, far from the margins.
The road goes around the lagoon passing by Poço da Velha and around a swampy area, on the left side, until reaching again the big rock. At this stage, you should go up the crater to the viewpoint where you started the trail. Here there is a connection to other points of the island through the trail PR01COR - Cara do Índio.
This route is inserted on a Special Area of Conservation and a Special Protection Area, within the Natura 2000 network.
