I’ll throw my two cents in:
1. The black sand beach on Hana Bay on the island of Maui—particularly the part behind the Hana Kai Maui. Idyllic.
2. Papohaku Beach on the west end of Molokai. It is a golden strand two to three miles long, and it is possible that you will have it all to yourself. Not many people visit Molokai. When we were there, two other people were present. They soon left, leaving the entire beach for ourselves.
Yes indeed
That one came to my mind when I saw the article. When we were there, we had it all to ourselves. It probably doesn't get many visitors because Hana is so hard to get to.
My personal favorite is Hana, Maui’s Hamoa Beach:
