2 Step ( locally labelled snorkeling site for Honaunau Bay ) is the best accessible location on the Big Island for snorkeling when the seas are calm. I've snorkeled here dozen of times and I would highly recommend this for a great snorkeling experience.
Fairly easy access off of the 2 steps of lava into the bay. The water is exceptionally clear on calm days. I have seen turtles , eels, rays, and loads of different fish. Best snorkeling is up the reefs of both sides of the bay. Great outside of the bay on calm days.
Spinner dolphins regularly make appearance in the bay and seem to be comfortable swimming with people.
Surprisingly, I've never see any sharks here in all of the times snorkeling 2 Step. I'm sure they are around ( they inhabit all waters around the islands), i just have never seen them here.
Access can be challenging on rough days with the real challenge being the exit on high swell, choppy days
Be mindful of the small sea urchins living in the cavities on the 2 steps as you enter and exit the bay. Those spines in fingers or toes can ruin your day.
