Santiago Lake

Santiago Lake is a volcanic crater lake on São Miguel Island that fills an oval basin roughly 3 kilometers long and 2.5 kilometers wide at an elevation of 334 meters. Steep crater walls surround the water, creating a natural boundary that gives the lake its distinctive shape.

The lake formed through volcanic eruptions roughly 15,000 years ago, fundamentally shaping the current landscape of São Miguel. This geological history explains why the island contains multiple craters and water basins.

The lake holds meaning for local people, who have passed down stories about its waters across generations. This connection to tradition makes it an important part of how residents understand their island.

The lake is reachable via marked hiking trails that lead to multiple viewing spots with different perspectives on the water. Morning visits tend to offer clearer weather and less crowded pathways than later in the day.

The lake shore supports rare plant species like Azores juniper and buckthorn that grow only in this region. This vegetation makes the spot important for preserving local plant life, especially since southern slopes also supply water to nearby settlements.
