A crater lake sitting inside a dormant volcano in the Serra de Água de Pau, part of a protected nature reserve near the geographic center of São Miguel. The lake is one of the highest and least developed of the island's crater lakes, ringed by steep, largely untouched slopes, and reachable by a marked hiking trail down to its shore.
Lagoa do Fogo sits inside a dormant volcano in the Serra de Água de Pau, near the geographic center of São Miguel, and is protected as a nature reserve. Unlike some of the island's more developed crater lakes, its shoreline remains largely untouched, ringed by steep grass and scrub-covered slopes that drop directly to the water. A roadside viewpoint gives a wide panorama over the lake and crater rim without any walking required, while a marked hiking trail descends roughly 500 meters in elevation to the shore itself, a route that takes two to three hours round trip over uneven terrain. The lake takes its name, 'Lake of Fire', from the eruption that formed the crater in the 16th century. Visitors typically spend one to two hours at the main viewpoint, photographing the water from above, or commit half a day if hiking down to the shore and back. Weather changes quickly at this elevation; cloud commonly fills the crater by early afternoon even on days that start clear, so morning visits offer the best chance of an unobstructed view. The access road itself can close during storms, so checking conditions before setting out is worthwhile.
