Água de Pau

Água de Pau is a stratovolcano on São Miguel Island with a large crater basin roughly 4 kilometers wide. The slopes descend steeply toward the coast, and inside the crater depression you can see layers of rock from multiple eruptions.

The volcano last erupted in 1563, when ash and lava reshaped the surrounding landscape and altered the island's surface. This event left visible marks on the geology that you can still observe today.

Communities around this volcano have shaped their lives around the fertile ground, growing crops and raising livestock on slopes where volcanic minerals enrich the soil. The land use patterns you see today reflect centuries of adaptation to living on active volcanic terrain.

Start your visit from Vila Franca do Campo, where you will find lodging and restaurants to plan your day. The slopes offer several walking routes with different difficulty levels, so you can choose based on your fitness and time.

Beneath the surface, geothermal activity creates fumaroles and hot springs that locals use as natural heat sources. These features remind visitors that the volcano, though quiet now, remains thermally active underground.
