Fodor's Expert Review Waikamoi Nature Trail
Slightly after the town of Huelo, the Hana Highway enters the Koolau Forest Reserve. Vines wrap around street signs, and waterfalls are so abundant that you don't know which direction to look. A good start is between mile markers 9 and 10, where the Waikamoi Nature Trail sign beckons you to stretch your car-weary limbs. A short (if muddy) trail leads through tall eucalyptus trees to a coastal vantage point with a picnic table. Signage reminds visitors: "Quiet, Trees at Work" and "Bamboo Picking Permit Required." Awapuhi, or Hawaiian shampoo ginger, sends up fragrant shoots along the trail. The area has picnic tables and a restroom.
