Makena Beach State Park
Aquamarine water sparkles off the shore of this 3,000-foot-long, 100-foot-wide stretch of deep golden sand. Indeed, Big Beach—whose more-proper, Native Hawaiian name is Oneloa—is so beautiful that locals lobbied for the creation of a state park to protect it. For a dramatic, sun-drenched beach vista, climb Puu Olai, the steep cinder cone near the first entrance you pass if you're driving south. About the only time the view here is obscured is in the early afternoon, when the so-called Makena cloud rolls in. Swim with caution here: the shore drop-off is steep, and swells can be big.
On the other side of the cinder cone is Little Beach, which attracts bodysurfers and other free spirits, some of whom believe that clothing is optional, even though this is technically illegal. Skimboarders catch air at Makena's third entrance, which is a little tricky to find (it's just a dirt path with street parking). Access to all the beaches here requires paid parking and an entrance fee for non-resident visitors. Amenities: lifeguards; parking; toilets. Best for: surfing; swimming; walking.
