Yokohama Bay (Keawa'ula Beach), Oahu

Keawa'ula Beach, better known as Yokohama Bay, is the northernmost beach on Oahu's west shore. It is located a short distance just before the road ends and the trail to Ka'ena Point, the island's northwestern tip, begins.

This beach is truly off the beaten path. It is one of the most remote beaches on the island and is never crowded. You need a car to get here as the City Bus only goes up to Makaha Beach. In the winter months (November to February) the beach gets pounded by high surf. This is the time when many local and visiting surfers come here to experience some thrills in the churning white water. Lifeguards are present most of the time and for good reason. The rocky ocean bottom, strong currents and high waves can be dangerous especially for beginning surfers.

The Hawaiian name for this beach is Keawa'ula, meaning "the red harbor," named for the great number of squid that used to be found in the bay's nearshore waters. These squid have a bright red color when they reproduce. Most locals today refer to this beach as Yokohama Bay. Japanese fishermen in the early 1900s who came here to fish gave the beach this name, which later stuck in people's heads.

Yokohama Bay has fine sand and is backed by the Wai'anae Mountain Range. The beautiful natural scenery makes for great photo opportunities. The bay is part of Ka'ena Point State Park. From here a dirt trail leads north to Ka'ena Point, Oahu's northwestern tip.

Frequently Asked Questions

Why is Yokohama Bay also known as Keawa'ula Beach?

Keawa'ula is the Hawaiian name for this beach area, while Yokohama Bay is the more familiar local nickname many visitors recognize. Both names refer to the same far west Oahu beach near the end of the road.

What makes Yokohama Bay unique on Oahu?

It is the last sandy beach on the west shore before the road ends near Ka'ena Point. The open coast, dry hills and remote edge of the island give it a very different setting from the busier beaches closer to town.

Is Yokohama Bay good for swimming?

Swimming depends on the season and daily conditions. Summer can bring calmer water, but winter surf, current and shorebreak can be dangerous. Check with lifeguards before entering.

Can you reach Ka'ena Point from Yokohama Bay?

Yes. The Ka'ena Point trail starts near the end of the road past the beach. It is an exposed coastal walk with strong sun, little shade and no drinking water along the route.

Can you see wildlife near Yokohama Bay?

Hawaiian monk seals, seabirds and other coastal wildlife may be seen in the broader Ka'ena Point area. Give wildlife plenty of space and follow any posted protection signs.
