The Santa Cruz Lava Tunnels were formed years ago when the outer parts of lava created a thick rock wall for the lava to continue flowing within. Over the years, the flow subsided, and what remained are some magnificent tunnels made of solidified lava. The underground channels are large enough for visitors to walk through and explore, and they vary in length and don’t always interconnect. There are many tours available for visitors who really want to learn about the tunnels’ history. It is probable that visitors exploring the lava tunnels will come across barn owls and other types of birds.
