Hawaii Kai is one of the largest communities on Oahu's south shore. Here you will find a modest, but upscale selection of vacation rentals. One advantage of booking a Hawaii Kai vacation rental is that you will be close to Honolulu and Waikiki, where most of the fun and entertainment is happening on Oahu, but away from the hustle and bustle. If you plan to go snorkeling or do other ocean activities, Hawaii Kai is a great place to be since it is close to Hanauma Bay, Oahu's most popular snorkeling destination. Hawaii Kai is located at Maunalua Bay, a popular place for jet skiing, kayaking, canoe paddling, diving, fishing and boating.
