Algar do Carvão, Cave entrance in Terceira Island, Portugal
The volcanic cavern extends 100 meters in length and descends 90 meters through volcanic rock formations within the Guilherme Moniz volcano system.
Initial exploration of the cave occurred in 1893 when Cândido Corvelo and Luis Sequeira made the first descent using basic rope equipment.
The name derives from Arabic 'al-Gar', meaning 'the crease', while local inhabitants incorporate the cave's presence into their agricultural traditions.
Tours operate between May and September from 14:00 to 18:00, requiring visitors to navigate numerous stairs during the underground exploration.
The cave features silica-based stalactites, formed through mineral deposits, and contains a rain-fed lake that reaches depths of 15 meters.
