Maui, Hawaii, United States
Maui’s Grand Wailea resort has an extraordinarily elaborate pool complex. Its highlights: four waterslides, whitewater rapids, caves, a lazy river pool, rope swings, and a “water elevator” inside a man-made volcano. One of the four waterslides in Grand Wailea’s massive pool complex–the best in Hawaii. The resort also has a prime location on one of the best U.S. beaches.
