Waipio Valley, Big Island, Hawaii

Waipio Valley is the starting gateway to the Waimanu Valley adventure on the Big Island of Hawaii. The lookout down the road leading into the valley shows how steep the descent is — 4x4 vehicles can make it in wet conditions but it's not recommended for most cars. We parked at the art gallery for $20 per day to leave our car overnight.

Once at the bottom, follow the dirt road to the right toward the ocean, then head left along the black sand beach to the river crossing. Head upriver to find a shallower crossing point. From there the Muliwai Trail begins into the forest heading toward Waimanu Valley. A truly spectacular place that sets the stage for one of the best multi-day hikes in Hawaii.
