The best thing you can enjoy the island of Boracay are boating/Island hopping and snorkeling. it is 5-hour ride strolling around the island and with a stop over for snorkeling in a various spot to enjoy fish feeding.
For my experience I recommend the Allan Fun tours, they have the package with free foods. They have their own barbecue restaurant for your food after snorkeling.
You can find their booking station in front of Villa de Oro along the beach near station two, Owned and manage by Mr. Allan Brillantes.
Of course, there are dozens of boating & snorkeling in the island and the price may depend to their offered package.
For this activity you can see the beauty of the whole islands of Boracay in just a day.
