Top Terceira Audio Guides

The underground caves are one of the most amazing visits to make on Terceira Island. This tour includes passage through Gruta Natal (lava tube) and Algar do Carvão (inside the volcano), also includes passage through the famous Furnas de Enxofre (fumaroles) and the Lagoa das Patas leisure area. IMPORTANT INFORMATION: The Algar do Carvão is temporarily closed for museum reconstruction works; instead of Algar do Carvão, we will visit the Natural Pools of Biscoitos.
