Kailua Beach Park

If you like to windsurf (or simply to watch the sport), head near the town of Kailua on the windward coast and find a perch at the Kailua Beach Park. You'll also find plenty of families enjoying this two-mile stretch of golden, shaded sand, and warm, cobalt-hued water. And unlike some of the more popular Oahu beaches, Kailua is a shore you can stay by all day; the beach features picnic tables, restrooms, free parking, and a nearby café for refreshment. If you want to try out some watersports, there are rental kiosks right on the sand.
