Lagoa do Fogo is a mesmerizing crater lake nestled in the heart of São Miguel Island. This natural wonder is a testament to the region's volcanic heritage, with its name literally translating to "Lake of Fire" in English. The lake's striking appearance, characterized by its deep blue waters and lush green surroundings, creates an otherworldly ambiance that captivates visitors from around the globe. Geologically, Lagoa do Fogo is a caldera lake, formed approximately 15,000 years ago as a result of a massive volcanic eruption. The lake's rim is 575 meters above sea level, while the crater rim, which reaches Pico da Barrosa, is about 949 meters high. The inner flanks of the crater are dominated by the elliptical lake, which measures 3 by 2.5 kilometers and 30 meters deep. It is among the largest bodies of water in the Azores. The lake's unique shape and formation have created a habitat for a diverse range of flora and fauna, many of which are endemic to the Azores. From an ecological perspective, Lagoa do Fogo is a vital component of the island's biodiversity. The lake's unique ecosystem is characterized by the presence of endemic plant species, including the Azores juniper and the laurel forest. As for birds, the caldera is home to primarily small birds, but some larger birds also live in the area. Among them are the gulls, the kites, the Azorean Buzzard, the Azorean Wood Pigeon, the Azorean Common Blackbird, the Gray Wagtail, as well as marine birds such as the Yellow-Legged Gull and the Common Tern.
