Maniniholo Dry Cave, Natural cave formation in Haena State Park, Hawaii.
Maniniholo Dry Cave is a tunnel-like formation within Haena State Park that stretches about 1,000 feet into the mountainside with a spacious entrance and sandy floor. Inside, natural corridors and rock walls create a walking passage that narrows and darkens toward the rear.
This cave began forming during ancient volcanic activity on Kauai many thousands of years ago. Over time, water erosion carved and shaped its passages, creating the structure visible today.
Local Hawaiian stories connect this cave to Maniniholo, a legendary fisherman of the Menehune people, who carved it while recovering stolen fish. The legend remains central to how people understand and speak about the place today.
Bring a flashlight if you plan to venture beyond the entrance, as daylight fades quickly once inside. The sandy floor can be uneven in places, so wear sturdy shoes for steady footing.
Water continuously seeps from the walls, keeping the interior moist despite the name "Dry Cave." This steady moisture is a defining feature that sets it apart from truly arid cave systems.
