- Shallow cave in a coastal rock wall at Haena State Park was once a sea cave when ocean levels were higher.

The Waikanaloa Wet Cave is a shallow freshwater cave tucked into a rock wall within Haena State Park near Kee Beach on Kauai’s far North Shore. Surrounded by lush tropical vegetation and dramatic coastal scenery, the cave is one of several geological formations in the area shaped by ancient ocean activity.
Thousands of years ago, when sea levels were significantly higher, powerful waves carved openings into the limestone and lava rock along this stretch of coastline. As the ocean gradually receded, some of these sea caves became partially filled by freshwater springs emerging through the porous rock. Waikanaloa Wet Cave is often mentioned alongside the nearby Maniniholo Dry Cave, located across from Haena Beach Park, as well as Waikapalae Wet Cave, which sits slightly higher on the hillside above Waikanaloa.
Unfortunately, the cave and the surrounding area are now officially closed to the public due to safety concerns involving falling rocks. This closure was implemented as part of the Haena State Park Master Plan adopted in 2019. Because of these hazards, we do not recommend attempting to visit the cave.
The cave is located on the mauka (mountain) side of the road leading toward Kee Beach. However, the adjacent section of roadway is now closed to public vehicle traffic and is primarily used as an informal walking route by hikers and beachgoers returning to the Haena State Park parking area.
If you do find yourself near the cave, note that the water is not considered safe for drinking due to the potential risk of bacterial contamination, including leptospirosis. Swimming in the cave’s pool is also not advisable because of stagnant water conditions, potential bacteria, and the ongoing rockfall hazard in the area.
Additionally, non-Hawaii residents visiting Haena State Park are required to obtain advance reservations.
