Volcanoes National Park, a warning sign at one of the beaches where I snorkeled, loot from one of my snorkeling trips.
Not pictured: Tidepooling behind the house (the camera lens had sunscreen so the images came out crap). No snorkeling pictures (Puako bay, Beach 69, and Hapuna beach) as the coral was very mediocre. There were some cool and large fish at Beach 69, but it was not worth the trouble to bring the GoPro. Puako Bay was very choppy. I only dared to go out because there were other snorkelers and a dive boat further out, but holy crap was that a roller coaster ride ... and I didn't get to see jackshit!
