Visually this is one of my favorite beaches in Hawaii.
Napili Bay Beach is used primarily by guests of the Napili Kai Beach Resort and the smaller hotels to the south.
It is relatively wide beach and offers a great place from which to view the evening sunset. Swimming, especially around the coral formations offshore at the north end of the beach, can be excellent when the surf is calm. Beware of high winter waves.
The slope of the beach as it enters the ocean is rather steep and drops away quickly. This is great for those who want to swim or snorkel, but families with children need to watch them carefully.
Parking for non-guests can be difficult and is mostly along the street.
