After going high in the parasail, go low by snorkeling the reef. Great guide is Alfonso Graniel, L'il Alfonse, (above, "Goods and Services" drop down menu). Since you will only be on island 1 day, it might be a good idea to call him before you leave the US to schedule: 011-501-226-3537, 011-501-614-5450. With a Sam's Club AT&T phone card, you can call Belize for 25 cents per minute from the US. Fly out of Belize City Municipal - cheapest flights. Have a great day there!
