The West coast is unique on the island because it is “protected” by the massive Waianae mountain range. What I mean by this is that the Waianae mountains block any major passage to the West Coast except for the area that is just South of the Waianae mountain range. There are no major mountain passes over the mountain range, and the small area between the North Shore and the northern tip of the West Coast doesn’t have an accessible road connecting the two. This keeps the West Coast far less crowded with tourists than other areas of the island, especially the further North you drive.
I wanted to get as far North as I could (by car at least). At the Northern most part of the West Coast lies the Yokohama beach and Yokohama bay, both more commonly referred to simply as Yokes. The beaches at Yokes are pristine and uncrowded. There’s no busy roads or traffic, so it’s quite and relaxing. There are some scattered rocks, but for most part nice white sand. The waves brake hard in certain spots, but other spots are calm and allowed easy access with the Hala boards. The water was clearer than any other beaches that I visited in Hawaii. You can see the coral and fish from your board as you paddle around, and it would be a great idea to bring snorkel gear.
