Cayman Brac has a series of caves that are open for exploring. Peter’s Cave, on the Lighthouse Trail in the East End, is mammoth, with tunnels leading off in several directions. Rebecca’s Cave lies off South Side Road, near the Carib Sands Beach Resort, and is well marked. It’s the best known of Brac’s caves, and takes its name from a young child who died here during the disastrous hurricane of 1932 that destroyed the island. Rebecca’s tomb can still be seen in the middle of the cave.

Bat Cave takes its name from its inhabitants, several species of which can be seen hanging from above if you shine your flashlight up to the roof. Most of the bats you’ll see here are Jamaican fruit bats. The bats emerge in the evening to fly about, usually after 9pm. Bat Cave is on the south side of the island and is marked by signs.

A final cave, Great Cave, stands a mile or so from the lighthouse that designates the easternmost point of the island, at the top of the Bluff. Filled with stalagmites and stalactites, it is one of the most interesting caves to explore, although a bit eerie. The terrain is dry and rocky, with plenty of sharp, loose rocks. Wear long pants and sturdy shoes, preferably with ankle supports, for scrabbling around underground.
