Fodor's Expert Review Keanae Arboretum
Here you can add to your botanical education or enjoy a challenging hike into the forest. Signs help you learn the names of the many plants and trees now considered native to Hawaii. The meandering Piinaau Stream adds a graceful touch to the arboretum and provides a swimming pond. You can take a fairly rigorous hike from the arboretum if you can find the trail at one side of the large taro patch. Be careful not to lose the trail once you're on it. A lovely forest waits at the end of the 25-minute hike.
