Koke'e and Waimea State Park
After two miles on the Pihea Trail is the junction with Alakai Swamp Trail. The scenery drastically changes from open valley to rainforest as you head into Alaka'i Swamp, the world's highest rainforest and swampland fed by the abundant precipitation on Wai'ale'ale's slopes. The trail is said to be the highlight of many visitors' journeys to the island, and it's one of our favorite hidden gems as well. As a bonus, in the last few years the trail has been greatly enhanced with boardwalks. No longer do hikers have to trudge through the mud to reach the magical lookout of Kilohana at the end of the journey.

Before you drive to the trailhead, check the trail and weather layer.
Hawaii hikes can change quickly with closures, rain, mud, heat, and daylight.
To help clarify this junction and the two trails, we've created three maps below: one is a Pihea Trail map alone, one a Alakai Swamp Trail map alone, and one that shows the preferred route that combines the two (from Pu`u o Kila at the end of Highway 550 to Kilohana lookout), here known as the Pihea and Alakai Junction Trail map.

Kokee and Waimea State Park
Don't forget to check our Koke'e State Park Hiking page for information on all the incredible trails inside the park. On that page we've also posted a map of the entire area (Koke'e and Waimea State Parks) for you to download and print out at home.
The Koke'e Lodge and Museum will also have maps available, but we'd definitely advise you to go ahead and review the map and become familiar with the area. The crisscrossing of trails and 4x4 roads can be confusing at first, but once you select your routes, it's not too bad. Feel free to contact us if you have specific questions.

Dry conditions on Oʻahu today, with breezy wind in exposed areas. Drier weather continues through Wednesday as moisture clears out.
A medium-sized northwest swell will bring elevated surf to north and west-facing shores tonight through Sunday morning—conditions may briefly reach advisory levels. East-facing shores stay rough through the weekend. Winds remain breezy through Sunday, easing slightly Monday and Tuesday before picking up again Wednesday. A Small Craft Advisory is active through Monday morning for most coastal waters due to wind and sea state. Scattered showers arrive Thursday into Friday.
South and west shore beaches work well through Sunday for calmer conditions. North shore is worth watching tonight and Sunday morning if you're drawn to bigger waves.
