You can have a lot of fun watching from the boat. LOOK DOWN when actually in the water. The dolphins will often swim right underneath you or from behind you. Be willing to snorkel below the surface but be careful and aware of your own limitations. If you feel uncomfortable in the water, ask your Dolphin Guide for suggestions.
Snorkeling is a fun sport, but only when one is comfortable.
When surfacing to breathe, look up to avoid any potential objects in your way. Be ready to enter the water and be ready to exit when told to do so. When entering, go feet first, holding your mask against your face with your snorkel in your mouth. Generally, look up and forward to see the boat. With waves, it can be difficult to see the boat from underwater.
