This is a small park about 15-30 minutes from Waikiki depending upon traffic. The beach is very nice, there are some low coconut trees and shaded areas. It's a popular location for many Hawaii wedding websites because of it's convenience consequently, there may be one or more weddings happening at the same time.
We recommend the mornings and mid afternoon from 10:00 am to 2:00 pm as the best times though, as late as 4:00 in the Summer and 3:00 in the Winter work well depending upon the sky. Note: the parking area is small and it can get busy in the afternoons with no parking.
