Honolua-Mokulē‘ia Bay Marine Life Conservation District is off SR 30, just past Milepost 32. The district is composed of twin horseshoe-shaped bays separated by a rocky point. Mokulē‘ia Bay, which is not visible from the road, is accessible via the concrete steps near the parking area. A favorite among snorkelers, the bay is relatively small with a sandy pocket beach. On the west side, a small stream empties into the ocean.
Less than a mile east of Mokulē‘ia Bay on SR 30 is a dirt trail that leads to the slightly larger Honolua Bay. The beach is covered in a jumble of smooth, rounded boulders, and an intermittent stream drains into the sea. Snorkelers can spot coral, sea turtles and a variety of fish.
Note: Swimming is not recommended at either beach during the winter months when high surf is common. Parking is available only along the highway.
