Waialae/Kahala Beach is just past Diamond Head a couple of miles east of Waikiki.
The spots we use is up the beach about a 150 yards from the parking. If you have mobility challenged people, look at Waimanalo or Magic Island.
We perform ceremonies either on the sand or on one of the grass spots under the shade of the coconut trees.
Ceremony times at 9 am or 10 am are best. It's cooler, good for photos, less busy, and parking is generally available. After 10 am, parking is tough, use our transportation, taxi, Uber, or Lyft. If not, arrive at least 30 minutes earlier than we schedule to wait for parking.
FYI: Given the closure of use by the government for our premium Windward beaches (Waimanalo and Makapuu), Waialae/Kahala has become very busy throughout the day and especially starting mid-morning on. Parking will be tight or not available in most cases. We suggest being dropped-off.
