There’s no beach at the Halekulani. Just rows and rows of sun loungers on grass. Yes, there is a little gate on one side of the hotel thst will let you out onto the very crowded public beach. Surf was too rough to swim, float when we visited.
Service is good but not great when we were there three years ago. LOTS of weddings. Do eat as much coconut cake as you can.
I’m not wild about Oahu.
