Waimanalo is one of the world's great beaches. It's up there with Big Beach, Maui, Hawaii; Half Moon Bay, San Mateo, California; Byron Bay, New South Wales, Australia; Ninety Mile Beach, Victoria, Australia, and; Puerto Escondido, Oaxaca, Mexico. All of these incredible beaches are accessible, have a huge crescent bay, and have a lack of development (buildings) seen from the beach. i.e. remote feeling but not incredibly hard to get to for those who seek beautiful, well-formed waves, fine sand, natural beauty and hopefully not too many people. Zuma Beach, Malibu, California is a mini version, but very sweet nonetheless.
These are from my experience, so don't shoot me if I missed your patch of sand. Australia and other places have other big beaches, but most are pretty remote.
Out of all these beaches, though, Waimanalo has a special feel of its own. Waimanalo is the only one with close mountains, seconded by Byron Bay that has views to the near distant mountains. Besides Big Beach, that views the island of Lanai (very cool), Waimanalo is the only one with an island offshore - Rabbit Island and others.
You can FEEL the ancient Hawaiian culture at Waimanalo, and this place has been a battleground for preserving traditional values, both at the beach and Mauka. I know even the most hardcore Hawaiian natives, of which there are too few, know that there are white dudes (and others) like me that respect this place for being one of the best in the world. You can stand on this beach and drink in the natural beauty, and it costs you nothing - how cool is that? Spend some time here and the visions are powerful enough to leave an imprint on your soul.
I understand that the Hawaiian islands are in the chain of islands reaching up to the Aleutians, that are some of the oldest islands in the world. It is incredible that the lava rock just doesn't break down. With the powerful currents that hit these shores, they take a lickin' and keep on tickin'. Lets preserve Waimanalo.
