Aside from swimming, snorkeling, banana boat rides, para-sailing and other activities that could be done on the beautiful island of Boracay in the Philippines, there is also Helmet Diving ! Check it out.
Reef walking with crystal clear warm water, at one with beautiful sea creatures and an odd-looking helmet on your head.. what could be more exciting? Price for a helmet dive is around US$ 12-15. For safety, just remember to follow the diving instructor well.
