We couldn’t take any pictures in the Actun Tunichil Muknal Caves, but they were really cool so we’re making a post anyway with random internet pictures.

We had to swim to get into the cave.

Some places we had to swim, and some places we had to wade, and some places we had to climb.

On the way out we had to take a very tight waterslide in the dark. We had to bend our head at a weird angle to fit into the crack to get in.
