A snorkeling area lies adjacent to the park among the coral gardens of Honaunau Bay. Make sure to practice ocean safety and check for any high surf or weather advisories before planning your snorkeling trip. The snorkeling in this area is recomended for those with strong swimming skills and those comfortable with swimming in deep water. Parking at the snorkelling area is limited, so plan to arrive early.
In order to preserve the cultural landscape within the park, and to protect the numerous threatened sea turtles that swim offshore, snorkellers are asked not to enter the water at Keone'ele Cove.
