Bellavista is located in the highlands of Santa Cruz and is the point of access to around two kilometres of lava tubes that run underground. These tubes were formed when surface lava cooled and solidified, while the underground hot lava continued to flow.
A path leads visitors through a small opening in the ground and into the tunnels. The beginning of the tunnel looks almost man-made and artificial lighting provides a yellowish glow. Further into the tubes the tunnels become darker, the floor slippery and the path increasingly rocky.
As the entrance to the tubes is on private property, visitors do not need an official guide however a small entrance fee is charged.
