1. Manele Bay, Hawaii
Hulopo’e Beach on the island of Lana’i, long considered one of the world’s most perfect stretches of sand, lies at the base of the Four Seasons Lana’i at Manele Bay. The resort overlooks the bay, a designated marine preserve filled with colorful fish and the occasional spinner dolphin. In fact, snorkeling and diving spots here are considered some of the finest in Hawaii, making a swim in the 70-degree water all the more tempting.
