Kailua, the once-sleepy community on Oahu’s Windward Side, is often associated with its beaches. Kailua and Lanikai beaches are world-renowned, luring thousands of visitors annually with their golden sands and aquamarine waters. But the appeal of this beachy town, flanked by the Koolau Mountains and crescent-shaped Kailua Bay, goes beyond its stretch of sand. Some of the island’s best restaurants and boutiques are in Kailua.
