Oneuli Beach, also known as Naupaka Beach, is a secluded black sand beach located in Makena State Park, South Maui. It is situated north of the Pu'u Ola'i cinder cone, a prominent geological landmark. The beach is known for its unique dark sand, which is a mixture of black, white, and red hues, created from the erosion of volcanic lava. Oneuli Beach is a paradise for snorkeling and diving enthusiasts due to its abundant marine life, including green sea turtles and occasional sightings of manta rays and small sharks. However, swimming conditions can be challenging due to strong currents and the presence of a hard lava shelf at the water's edge. The beach offers no facilities, making it a more rugged and natural experience for visitors.
The beach is accessible via a dirt road, which adds to its secluded and off-the-beaten-path charm. Visitors must be mindful of the rough terrain and potential hazards like sharp volcanic rock and strong ocean currents. Despite these challenges, Oneuli Beach provides a unique and educational experience for naturalists and geology enthusiasts.
The surrounding area offers stunning views of the cinder cone and the opportunity to explore the nearby Maluaka Wetlands, which are part of a historic fishpond restoration project.
