Chilled out at the famous Mauna Kea Beach Resort which fronts the bay. The Mauna Kea Beach is one of the nicest beaches on the Big Island with awesome snorkeling. If you are not a guest at the resort you can request a beach access pass from security at the entrance to the resort. Arrive early, the passes are usually gone by 0830 as they only have 40 public access parking spaces. The really determined can do the 1 mile ocean trail hike from Hapuna Beach State Park if the parking spaces are filled.
