Lagoa do Fogo is a beautiful crater lake located in the center of São Miguel island, which is part of the Azores archipelago in Portugal. The lake, which is surrounded by mountains and lush vegetation, is one of the largest freshwater lakes in the Azores, with a depth of around 30 meters.

The lake's name, which means "lake of fire" in Portuguese, comes from a volcanic eruption that took place about 15,000 years ago. The eruption created a large caldera that eventually filled with water from rainfall and underground springs, forming the Lagoa do Fogo.

The area surrounding the lake is a protected nature reserve, and it is home to a variety of plant and animal species, including several species of birds and rare plants. The lake is also a popular destination for swimming, hiking, and bird watching. There are several hiking trails around the lake, which offer stunning views of the surrounding landscape.

To reach the Lagoa do Fogo, visitors can take a 30-minute drive from the capital city of Ponta Delgada, or take a guided tour that includes transportation and a visit to other attractions on the island. The lake is a must-visit destination for nature lovers and anyone seeking a peaceful and beautiful setting in the Azores.
