Dive, dive, dive!
Wreck of the Balboa:
This 375 foot freighter sank during the 1932 hurricane, and was later dynamited to clear the harbour for safe shipping.
Wreck of the Cali:
The Cali sunk in George Town harbour when, according to the stories, her cargo of rice and grain got wet and swelled so much that it popped the rivets in the hull and sank the ship.
These huge sponges are a common feature on Caribbean reefs, but remain very impressive for the sheer size they can reach.
These are especially impressive at night when the polyps come out to feed.
With a little bit of luck, you might be able to spot a turtle slowly going about its business as you descend.
