Kahana Bay Beach Park: Everything to Know

Kahana Bay Beach Park Opener

Kahana Bay Beach Park is one of the most hidden beaches on Oahu, Hawaii. If you visit on a week day, there won’t be more than a handful of people! And there’s so much to do there! Here’s everything you need to know about this amazing beach.

Where Is Kahana Bay Beach Park?

Kahana Bay Beach Park is located on the eastern coastline of Oahu – between Waikiki and the North Shore. There are two small designated parking areas for this beach. The northern parking lot tends to be much busier than the southern parking lot.

When Is the Best Time to Go to Kahana Bay Beach Park?

Because Kahana Bay Beach Park is connected to Kahana River, there is a lot of runoff from the river on and after rainy days. When there is runoff, the water in both the river and the bay can get quite murky, and the sand can gather an unpleasant layer of red dirt on the top. For these reasons, the best time of year to visit this beach is during the summer, as there are significantly fewer rainy days as when compared to the winter months.

As for the best time of day to visit, any time of day is a great time to visit the picture-perfect beach. However, this beach is one of the best places to catch a stunning Oahu sunrise!

What Can I Do at Kahana Bay Beach Park?

Go for a Snorkel

If it hasn’t been rainy for a while, the waters at Kahana Bay Beach Park will be remarkably clear! Plus, many fish like to hang out in the comforting protection of the bay! That makes it a fantastic area to go snorkeling! So strap on your gear and see what lovely sea creatures you can find!

Enjoy the Isolation

Kahana Bay Beach Park is surrounded on three sides by the towering mountains of the Koolau Mountain Range. The remaining side leads out to the Pacific Ocean. On top of that, during the weekdays, very few people can be found here, due to the fact that this beach has remained a secret (on the whole). So take some time to breathe in the fresh air and enjoy the isolation.

Kayak Around

Kahana Bay Beach Park and Kahana River are popular places to kayak. The calm waters make it perfect for beginners to test their skills (and their arm muscles) without having to struggle against a strong current.

*Note: You will have to bring your own kayak, have a kayak delivered to you, or take a kayak tour. For more information, here is a post with more information on the best places to kayak on Oahu.

Kahana Bay Shells

Search for Shells

On a day when the water is clear, there are surprising number of small, colorful shells lining the shores of the beach. (The same can’t be said of murky water days.) But don’t take every pretty shell that catches your eye! Be sure to leave some on the beach for others to find.

Check Out the Ancient Hawaiian Fishpond

In the southern section of Kahana Bay Beach Park, there is Huilua Fishpond, an ancient Hawaiian Fishpond. The Huilua Fishpond was actually in working condition up until the late 1960s, which is quite remarkable considering that it would’ve been quite a few centuries old by that point. Despite the fact that the pond is not currently in working condition, fish do tend to dart in and out of the pond. Huilua Pond is only one of only six ancient Hawaiian fishponds on the entire island of Oahu.

Try Your Hand Fishing

The ancient Hawaiians knew the fish would head to this bay. So why not try your hand at fishing? Odds are, you’ll see some locals casting out their lines as well.

Spend a Night Camping

On the weekends, Kahana Bay Beach Park can be popping! Why? Because now people (on the whole, the locals) can camp with advanced reservations! There are only ten campsites in the park. Fees start at $12 per campsite.

*Note: Petty theft is quite common at this particular beach. Don’t leave any valuables in your car. Furthermore, don’t leave anything that could potentially hold valuables (e.g. bags) visible. Hide them in the truck of your car, in the glove compartment, or under the front seat (think airplane-style).

What Else Is There to Do Nearby?

Go on a Hike

Kahana Bay Beach Park is in a relatively isolated part of the island of Oahu. Besides visiting the beach itself, the only other activities to do nearby is to go on a hike. Both the Instagram-famed Crouching Lion hike and the Puu Maelieli Trail are located close by. (And they both made it onto my list of the 15 best hikes on Oahu! Do note that both of these hikes are illegal.

*Note: Kahana Bay Beach Park is the beautiful lagoon that you see from the end of the Crouching Lion hike.
