The shore is fairly protected from wind and in the afternoon is a great place to sun worshipers. Fortunately, the "Makena cloud" settles in often, giving the sand much desired cooling periods.

Little Beach, also known as "Puu Olai Beach" is a small beach just North of Big Beach separated by a steep lava outcropping (the tip of Puu Olai) and a 5 minute hike.
