Also known as "A-bay," this expansive stretch of white sand mixed with black lava grains fronts the Waikoloa Beach Marriott and is a perfect spot for swimming, windsurfing, snorkeling, and diving. Although damaged by the 2011 tsunami (about 50% of the beach is gone) it's still a vital and popular beach. The bay is well protected, so even when surf is rough on the rest of the island, it's fairly calm here. Snorkel gear, kayaks, and boogie boards are available for rent at the north end, and the vendors are friendly and helpful. Snorkel cruises and glass-bottom boat tours also depart from this bay. Behind the beach are two ancient Hawaiian fishponds, Kuualii and Kahapapa, that served the Hawaiian royalty in the old days. A walking trail follows the coastline to the Hilton Waikoloa Village next door, passing by tide pools, ponds, and a turtle sanctuary where you will often see sea turtles sunbathing on the sand. Footwear is recommended for the trail. Amenities: food and drink; parking (no fee); showers; toilets; water sports. Best for: snorkeling; swimming; walking.
