Waikanaloa Wet Cave is one of two wet caves in the area; Waikapalae Wet Cave is the other. Located just off the highway it is the most easily accessible.
The caves in this area were formed when sea levels were much higher and sand and surf carved them out. Both wet caves are fed from underground springs which dump into the ocean. The level of water in the caves is affected by the tide. Swimming is prohibited in this wet cave. Some legends say that these caves were built by the volcano goddess Pele for her lover but when they filled with water, she abandoned them.
From Ha'ena, take Highway 560 west. Both wet caves are located on the left just before Mile Marker #10, past the Ha'ena Beach Park. This cave is on the right of the parking lot and closer to the road.
