Easily one of the most beautiful beaches in the world. If you are planning to visit, I highly recommend renting a jeep or other 4wd car as the road in is not paved and is very bumpy- and has huge mud ditches when it rains.
The beach itself is very wide white sand that overlooks the cliffs of the Napali Coast.
There are no food options here and shade is limited, so pack a lunch and rent chairs or umbrellas from your hotel. Some people will just back up their jeep to the beach and sit on the tailgate and hang out.
There are restrooms scattered about the park but there are no lifeguards.
The day we visited, the water was pretty calm.
