The beach facing Waialea Bay is predictably named Waialea Beach, and it is part of the Waialea section of the Hāpuna Beach State Recreation Area. It's perhaps more commonly known as Beach 69, named for the number on a nearby utility pole. However you want to refer to it, this beach is a great alternative to its much larger and more developed sibling to the north, Hāpuna Beach, and it really deserves a visit.
As with the Hāpuna Beach area, there is a fee for non-residents to park here, and restrooms and showers are available along with a modest number of picnic tables that enjoy some shade from the trees. That's all for development, however; walk toward the beach (past innumerable warning signs) and let the trees take over, for this beach really belongs to them. It is a long stretch of sand with abundant tree coverage and pockets of clear sand. The effect is almost like a gallery of pocket beaches separated by entangled root systems and branches. Beachgoers can find small and private pockets or opt for the larger spaces with more sun exposure and room to spread out. Kids have just as much fun exploring the trees as the ocean and sand, and there is no shortage of shade for those who prefer to stay out of the sun.
To the north lies the main beach section, a larger stretch of sand where the waves come in with more shape and force and are more suitable for boogie boarding or body surfing. Use your judgment when evaluating surf conditions, which can pound swimmers from time to time. There are no lifeguards here.
Note that pets are not allowed here or at Hāpuna Beach.
