Like to snorkel? I certainly do! I got a taste of true marine off the Na Pali coast in Kaua'i. Huge friendly sea turtles roam the waters and large, brightly-colored fish swarm near the reef. It may be expensive to travel to Kaua'i and book a trip with the private Na Pali snorkel/mini-tour service but it's worth the beautiful sites!
On the other hand, does anyone know of good snorkel spots on the West Coast?
