It's and Island.

And there's not too many people there.

That's why there's not too many activities.

But....

Snorkeling
Swimming
Boating
Fishing
Jungle Treks
Sunning
Relaxing
Exploring

Scuba diving just opened on the island as well.

If you're staying at one of the beach bungalows, they'll be glad to help keep you busy. (or not).
