– When we arrive at Gruta das Torres, we will get our equipment for the upcoming underground adventure with a helmet and flashlights.

– During the guided tour of approximately 1 hour, we will visit around 500m of the total 5,150m long lava tube.

– The tube extends from Cabeço Bravo towards Criação Velha lava fields. Along the cavity, we will discover rare and valuable bacteria, as well as interesting formations. Namely, ropy lava, stalactites and stalagmites, side benches, and lava balls.
