The largest sand beach between Kailua-Kona and Keauhou is the popular Kahalu'u Beach Park, adjacent to the Keauhou Beach Resort.  This gray sand beach is one of the most popular swimming and premium snorkeling sites in the Kona district.  Home to the green sea turtles, the area is also teeming with a good variety of marine life and beautiful tropical fish which seem to be nearly tame. Kahalu'u Beach Park is by far the easiest and safest place to snorkel on the Big Island as it has a protected reef from ocean surf.  The calm water, marine life, and crystal clear water depths of 2 to 20 feet make it a spectacular place to swim and snorkel.  Beyond the reef area, the water depth is much deeper and a bit rougher for the more adventurous.  The area is also an ideal place for scuba diving and sunbathing! Showers and restrooms are available. There is also a snack wagon usually on site as well as a place to rent umbrellas and snorkel gear!!
