Accessible by trail only. 1/4 mile north of the Na Pali-Kona Forest Reserve Entrance. Kokee Road (Hwy 550).
(West Side)
The once-fiery crater at the top of Mt. Waialeale is now the Alakai Swamp - a magnificent bog located in a wet depression below Mt. Waialeale summit - a superior wildland that is the highest and largest high-elevation swamp in the world. A trail leads across the swamp through scrub native rain forest and shallow bogs. The swamp is home to seldom seen rare plants and native birds and there are excellent opportunities for bird and botany observation. The trail ends at a vista called "Kilohana" on the edge of Wainiha Pali. On a clear day, the views of Wainiha and Hanalei Valleys provide for an unforgettable experience. If you hike this route, be sure to wear appropriate clothing. There is boardwalk but the trail is often wet, slippery and very muddy. The seven rivers that trail out from Alakai Swamp and down to the sea include the Waimea River, Hawaii's longest river.

Respect, Enjoy, and Conserve our Forest Resources
Here are some ways to show that you care about your sport.
  1. Stay on the designated trails and roads. Riding off the trail/road destroys vegetation and can cause erosion.
  2. Know where you're permitted to ride and where you're not. Respect private property and closed areas.
  3. Always be courteous when you pass hikers and hunters on the trail or other vehicles on dirt roads. If hunters have dogs with them, stop your bike and let the hunters gather their dogs before you proceed.
  4. When you meet a horseback rider, go slowly and stop on the outside of the trail. Take off your helmet and say hello. Speak in a calm, normal voice. The horse needs to recognize you as a human. Avoid any sudden movements.
  5. It is recommended that riders stay on the designated roads, rather than riding on foot trails. Listed trails are open to bikes but should not be ridden when the trail is wet. Bicycle tires can cause serious soil erosion and deteriorate the ecosystem. Some listed trails are steep and can be very dangerous to both the rider and hikers.
  6. When biking on weekends and State holidays, you should wear bright colored clothing. You are sharing the area with hunters.
