Kailua Beach Park, Oahu, HI, USA - stock photo

A cobalt-blue sea and a wide continuous arc of powdery sand make Kailua Beach Park one of the islands 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.
