Waiale'e Beach Park is located on the North Shore of O'ahu and is not to be confused with the Waialae Beach Park near Kahala on the South Shore. This is a small white sandy beach with some tide pools and a little island right off the coast. There is no surf here, and this is not a popular beach by any means, but it's perfect for anyone looking to get away from the crowds at the famous beaches nearby. This is one of the most eastern beaches on the popular stretch, so it's an easier trek for people living or staying on the windward side of O'ahu. There is a bunch of parking considering how rarely people come here, and there is plenty of shade for a long stay. The water isn't too rough here other than in the winter, and there are some rocky areas to walk around and check out the little fish in the tide pools. You can swim out to the island, but there is no beach and the waves crash steadily on the rocky coast, so be careful.
This isn't the place you are going to brag to your friends about going, but learning about the less-popular spots on the crowded island of O'ahu is the real way to enjoy the area like a local. It's a good family spot because of the calmer waters and mellow vibe. There are no showers or bathrooms, however. The snorkeling isn't bad for O'ahu, so bring a mask if you have one. Watch for incoming waves and the slippery rocks while enjoying the tide pools.
