Kailua is a breezy beach town on the windward side of Oahu, loved for some of the prettiest beaches in all of Hawaii. It has a relaxed, small-town feel by the sea.
You can swim at Kailua Beach and Lanikai Beach, paddle a kayak to little islands, and fly kites in the steady wind. The soft white sand and blue water make it perfect for a beach day.
This wide beach has soft white sand and calm turquoise water, making it a favorite spot for swimming and kayaking.
Two little green islands sit just off the shore, and adventurous families paddle out to see the seabirds nesting there.
