Date of visit (Jan 20) Stayed in Campsite #6 Like many campground in Oahu the campsites were very close together. We lucked out and there were not many campers in the park after 8pm. However during the day this Regional Park does get very crowded with weekend activities, parties, and tourists.
The Kualoa A site is tucked away from the massive crowds there to see Chinamans Gat and is a nice spot to listen to the waves gently crash against the shoreline.
Bathrooms worked, showers were very cold (expected), and there is a nice sink outside the restrooms to scrub dishes.
Would stay here again.
