Kahana Bay Beach Park, Oahu

Surrounded on three sides by the majestic Ko'olau Mountains, Kahana Bay is one of the best-kept secrets of windward Oahu. The crescent shore is set against a beautiful backdrop of ironwood trees and the steep and lush Ko'olau Mountain Range. The sandy beach is a great spot for sunbathing, and the ironwood trees provide plenty of shade for a picnic. On the south end of the bay where Kahana Stream enters the ocean is an ancient Hawaiian fishpond called Huilua.

The waters are generally calm, but few people go swimming here because the water is murky from the runoff of Kahana Stream and the nearshore ocean bottom is rocky. Local residents like to camp here during weekends, so this is when the beach can get busy. A camping permit is required. See here for info on how to get a permit.

Very scenic views when the rains aren't clouding them; water is warm and chest-level out to about 400 meters from shore, the mountains surround the bay and the parasailers make their landings on the beachfront near the mouth of Kahana Stream. The terminus of the stream is swimmable, the water is cold and clear(spring-fed), but there are dozens of local kids diving from the heavily trafficked bridge that passes 10-12' overhead. Grounds are fairly well maintained, but facilities are cleaned once or twice weekly; so, by Saturday afternoon, the Port-o-potty isn't fit for man nor beast! All in all a nice park, but book early and guard your site carefully...lots of car, foot(loud music) and animal traffic day and night!

One of the most scenic locations on the island! Swimming isn't really possible here, but the views are fantastic!
