Mermaid Cave / Tunnels
About
On Oahu, Mermaid Cave / Tunnels sits at 89-435 Keaulana Ave, Waianae, HI 96792, United States, a coastal attraction known for its sea cave and tunnel formations. The site draws visitors who come to explore the rocky shoreline and the natural openings carved by the ocean. Its location on the leeward side places it within reach of several communities along the western coast.
First-time visitors can expect a rugged, unguided environment where the main appeal is the cave and tunnel structure itself. The terrain is uneven and the area is exposed to the elements, so sturdy footwear and caution are sensible. With 356 reviews contributing to a 4.5 out of 5 average, the site has clearly resonated with those who have made the trip. Nearby Honolulu and Waikiki lie to the east, while the North Shore communities of Haleiwa and the windward town of Kailua sit across the island.
Opening hours are not available, so timing a visit around daylight is advisable. The listing does not include photographs or a website, meaning visitors rely on the location alone. The address at 89-435 Keaulana Ave anchors the site in Waianae, on the drier leeward coast.
Oahu's leeward side receives less rain than the windward coast, which makes the western shore a practical choice when trade winds bring showers elsewhere. Reaching Waianae from the main resort areas means travelling around the island's southern tip, a drive that passes Pearl Harbor and the communities of Waimanalo and Lanikai on the way. Visitors should carry water and sun protection, as the exposed coastline offers little shade.
