3 St. Regis Princeville Resort, Kauai, Hawaii.jpg

This is one of Hawaii’s most over-the-top resorts, and for good reason. Their infinity pool is approximately 5,000 square feet, and it overlooks the gorgeous Hanalei Bay. The pool features incredible glass tile, tropical gardens, and stunning water. Guests are also provided with snorkeling opportunities — you don’t even have to leave the resort.
