Kahana is sure to be an ideal spot if you are looking for trees for shade, picnic tables to enjoy a packed lunch, and there is seldom no more than a handful of people on week days.
The south end of the beach is quite empty and spacious, however the northern end of the beach near the jetty is a popular camping place. The water isn't very clear due to the runoff from the Kahana stream, but is great for those that want to kayak. It is also a popular local spot for fishing.
Kahana Bay Beach Park is 15 miles north of Kane'ohe on Hwy 83.
