Place: Playa de Sam Marcos, Tenerife
Cave: Cueva de Punto Blanco

During the O!bora cruise around the Canary Islands we wanted to visit several lava caves; unfortunately, our luck ran out and we had a chance to visit just one cave (and on the last day of our trip) - Cueva de Punto Blanco on Tenerife (200+ meters long, horizontal).

The path to the cave is pretty easy - a several hundred meter traverse of the high cliff above Playa de San Marcos. The entrance is about 3 meters above the path, but there's a wooden ladder which can be used to get inside.

The cave was extra interesting due to its origins, but moderately interesting otherwise. Two things to note: lava curbs and evident frozen lava flows. If a passage is blocked here, then it remains blocked - no mud to dig out! :)

Also, very warm (about 20 Centigrade - take a lot of water), very pointy but not sharp rocks. In the opening part of the cave very dry with a lot of dust; farther in, the cave's walls start to get a bit wet. Almost no formations except for some thin flowstone in places where water seeped in through cracks. Boiling lava left some small, stalactite-like protrusions hanging from the roof.

Earlier, in the same cliff wall and above the very same path there's an entrance to a much bigger cave (almost 2 km) - Cueva de San Marcos (near a metal pipe go up the white board with rungs). But we didn't visit this cave - I think we misunderstood the directions given us by the locals...
