On this beach, there were thousands of hermit crabs.

A times, it looked as if the entire beach was moving beneath your feet.

This day's trip had 2 activities: A hike on the island (an ancient burial ground), and snorkeling!

Graves were marked with cooking stones, and contained gold. Many have been desecrated.

Compared to the jungle on the mainland, this place was relatively quiet. No monkeys, few birds.

There were signs of some avian dining, however.

These stones are all over Costa Rica and parts of Central America.

No one knows how the indigenous folks got them so perfectly round... now what they mean.

The largest are over 2 meters in diameter.

View of the mainland from a lookout.

Night shot fun.
