Serra de Santa Bárbara, Dormant volcano in Terceira Island, Azores, Portugal.
Serra de Santa Bárbara is a dormant volcano on Terceira Island in the Azores, reaching 1,021 meters (3,350 feet) with a distinctive double caldera and two smaller peaks at its center. The mountain displays clear traces of past volcanic activity with visible rock formations and crater structures across its landscape.
The volcano experienced its last recorded eruption in 1761, when lava flowed from its eastern flank and created small domes still visible on the landscape today. This eruption shaped Terceira Island's geology and left volcanic features that define the island's appearance to this day.
The mountain takes its name from Saint Barbara and functions today as a protected nature reserve where locals and visitors encounter rare plant species adapted to island life.
The area is accessible through several walking trails including routes to Mistérios Negros and Serreta that connect different parts of the protected volcanic area. Weather changes rapidly at this elevation, so waterproof clothing and sturdy footwear are essential for any visit.
The mountain contains a wetland complex with peat bogs that attracts rare bird species found only in the Azores. These soggy habitats are unusual on volcanic islands and offer a striking contrast to the dry lava fields surrounding the area.
