Few things beat a day beside the sea. Round up the kids, throw together a picnic and enjoy the fresh air at Bellows Field Beach Park.
You'll be spoiled for sightseeing choice when staying in Waimanalo. Bellows Field Beach Park is a great place to kick off here, but there are lots of other worthy places to explore. Lanikai Beach, Kailua Beach, and Sea Life Park are close to the stretch of coastline and will fill in your day nicely.
