>>2868397most of the places you can snorkel are too crowded to have tiger sharks. If it helps any I've snorkeled all over the kona coast of big island and I've never seen a tiger shark in shallow water or met anyone that has.
avoid the places nobody is swimming though. Places like Kona harbor and off the point at magic sands people get eaten sometimes. Stay in the shallows.
if you want to be really sure just stick to Kahalu’u Beach Park where the entire reef is behind a breakwater that sharks pretty much can't get through. But even then stay away from the deep north end where the surfing school is because that's not protected and sharks do go there.
anyways you're way more likely to drown in hawaii than get eaten by a shark
the waves there get big
