A cobalt-blue sea and a wide continuous arc of powdery sand make Kailua Beach Park one of the island's best beaches, illustrated by the crowds of local families who spend their weekend days here. This is like a big Lanikai Beach, but a little windier and a little wider, and a better spot for spending a full day. Kailua Beach has calm water, a line of palms and ironwoods that provide shade on the sand, and a huge park with picnic pavilions where you can escape the heat.
This is the "it" spot if you're looking to try your hand at windsurfing or kiteboarding. You can rent kayaks nearby at Kailua Sailboards and Kayaks (130 Kailua Rd.) and take them to the Mokulua Islands for the day. Two-seaters cost $69 for four hours or $79 for a full day. Amenities: lifeguards; parking (no fee); showers; toilets; water sports. Best for: walking; windsurfing.
