Kahana Bay Beach Park and Kahana Valley State Park

Facts from DLNR’s park, trail and rules pages and its park-data feed, checked Oct 14, 2026.

DLNR calls it a “living park”: thirty-one families live in the valley and help run programs that share Hawaiian values and lifestyle. The park exists to nurture native Hawaiian cultural traditions in rural Windward Oʻahu (DLNR).

An ahupuaʻa is the ancient land division that runs from the mountains to the sea. Kahana covers almost 5,300 acres, from sea level to 2,670 feet on the Koʻolau crest, and DLNR counts it as one of only a few publicly owned ahupuaʻa in the state. Before Western contact it was a fishing and farming community, with kalo in irrigated loʻi and fish from the bay.

The road up the valley passes homes, and hikers use a designated lot before the residences (DLNR Nakoa Trail page). Groups that want a cultural program can call DLNR at (808) 237-7767. DLNR publishes no drop-in schedule for individual visitors, so this guide lists none.

DLNR lists two public trails, says no permits are required, and keeps trail maps at the Orientation Center (DLNR). They are very different hikes.

Kapaʻeleʻele. The trail starts at the Orientation Center on the old Koʻolau Railway bed, which hauled sugar cane to the Kahuku mill. It passes a fishing shrine and Keaniani Kilo, a lookout where a fish watcher spotted schools of akule. DLNR asks you to stay on the trail and not enter the shrine (DLNR trail brochure). The last section down to the highway is very steep and slippery (DLNR trail page).

Nakoa. Park at the hiker lot, walk up the paved road to the check-in station and sign in. The trail crosses Kahana Stream three times with no bridges, once on a narrow 40-foot concrete spillway. DLNR says not to hike it in heavy rain, warns of leptospirosis and says not to drink the stream water. Hunting is allowed in part of the area on weekends and State holidays only, so wear bright clothing (DLNR Nakoa Trail page).

Neither trail has drinking water, and bikes are not allowed on either (DLNR park data).

DLNR calls Huilua Fishpond the most impressive site in the valley. A mortarless rock wall about 500 feet long encloses 7 acres of the bay where stream water meets the sea. Huilua means “twice joined,” perhaps for the two gates that linked the pond to Kahana Stream. It became a National Historic Landmark in 1962 (DLNR fishpond brochure).

Tsunami damaged it four times in 80 years, the worst in 1946, and the Friends of Kahana, valley residents, now lead its restoration. DLNR says the fishpond can be visited from the east side of the bay (DLNR), and the Kapaʻeleʻele trail looks across at it. Walking on the wall is not recommended, and there is no fishing in the pond. DLNR publishes no parking spot for the east-side viewpoint, so this guide gives none.

Kahana Bay Beach Park is the shoreline in front of the state park. Honolulu Ocean Safety’s tower list has Tower 9 at Kualoa Regional Park and the next at Sunset Beach, with none at Kahana (tower list, last modified Aug 19, 2024), and DLNR lists no lifeguard at the park (DLNR park data). Treat the beach as unguarded.

We found no official page that describes waves or currents at Kahana Bay, so this guide says nothing about them. For a lifeguard, the closest tower to the south is at Kualoa Regional Park, about 5 miles away by our routing, and Kailua Beach Park has towers too.

The state Department of Health’s feed showed no open advisory for Kahana on October 14 (DOH water quality map) and lists two brown water advisories for Kahana Bay in early 2021. DLNR calls Kahana one of the wettest valleys on Oʻahu, so check the map after heavy rain and read our guide to swimming safely on Oahu today.

For gear, one operator rents kayaks and stand-up paddleboards for a three-hour trip down the Kahana River and out to the bay. It meets across the highway from the beach park.

DLNR lists restrooms, showers, picnic tables, trash cans, a water fountain, campsites and a boat ramp (DLNR park data). Winter hours began September 8, and there is no entrance fee (DLNR). DLNR publishes no stall count or Orientation Center hours, and its notices page listed no Kahana closure on October 14 (park notices).

Camping is by permit only, booked through the state’s Explore Outdoor Hawaiʻi site (DLNR).

• Cost. $20 per night per campsite for residents and $30 for non-residents.
• How to book. Create an account on Explore Outdoor Hawaiʻi.
• Storm closures. DLNR says reservation holders get an automatic refund minus the nonrefundable service charges.
• Not allowed. Open fires, alcohol and smoking. Pets are not allowed in campgrounds (state park rules).

Driving: DLNR puts the park 26 miles from Honolulu. From Waikīkī it is about an hour and 30 miles with no traffic, by our own routing (OSRM). DLNR’s directions say to take Likelike Highway or H-3 over the Koʻolau, then Kahekili Highway, which becomes Kamehameha Highway. Go through Kaʻaʻawa and the entry is in the coconut grove near the center of the bay. If you come over the Pali, the Nuʻuanu Pali Lookout is a short detour.

Pair it with Hoʻomaluhia Botanical Garden in Kāneʻohe, Kualoa Regional Park and the Kualoa Ranch tours. The full coast is in our east side Oahu drive guide.

Parking: park at the Orientation Center for the Kapaʻeleʻele trail and at the hiker lot before the residences for Nakoa. DLNR lists no parking fee.

TheBus: Route 60 stops at Kamehameha Highway and Kahana Bay. On the weekday timetable the 8:00 a.m. bus from Kona Street at Keeaumoku Street reaches that stop at 9:28 a.m., with buses roughly every 30 minutes (TheBus schedule data). Getting to Kona Street from Waikīkī is a separate ride.

DLNR lists motorized vehicles, alcohol, open fires, smoking and commercial activities as prohibited (DLNR park data). The state’s park-wide rules add no drones, no generators without a permit, and pets off beaches and out of swimming areas. Leave plants undisturbed and drive and park only on designated roads (state park rules). To report a violation, call 643-DLNR (643-3567). For an emergency, call 911.

Kahana suits visitors who want a Hawaiian cultural landscape more than a resort beach. Bring rain gear.

• Culture and history. The Kapaʻeleʻele loop and the Huilua view fit into about two hours.
• Hikers. Nakoa is the hard trail: stream crossings, mud and a 2 to 3 hour loop.
• Swimmers who want a lifeguard. Choose Kualoa Regional Park or Kailua Beach Park.
