Five minutes south of the airport in Lihue, you'll find this wide, sandy-bottom beach fronting the Kauai Marriott. This beach is almost always safe from rip currents and undertows because it's around the backside of a peninsula, in its own cove. There are tons of activities here, including all the usual water sports—beginning and intermediate surfing, bodyboarding, bodysurfing, and swimming—plus, there are two outrigger canoe clubs paddling in the bay and the Nawiliwili Yacht Club's boats sailing around the harbor. Kalapaki is the only place on Kauai where sailboats—in this case Hobie Cats—are available for rent (at Kauai Beach Boys, which fronts the beach next to Duke's Canoe Club restaurant). Visitors can also rent snorkel gear, surfboards, bodyboards, and kayaks from Kauai Beach Boys. A volleyball court on the beach is often used by a loosely organized group of local players; visitors are always welcome. Families prefer the stream end of the beach, whereas those seeking more solitude will prefer the cliff side of the beach. Duke's Canoe Club restaurant is one of only a couple of restaurants on the island actually on a beach; the restaurant's lower level is casual, even welcoming beach attire and sandy feet, perfect for lunch or an afternoon cocktail. Amenities: parking; showers; toilets; water sports; food and drink. Best For: swimming; surfing; partiers; walking. www.kalapakibeach.org.
