Fodor's Expert Review Keahua Arboretum

Tree-lined and grassy, this arboretum in the Lihue-Koloa Forest Reserve is a perfect spot for a picnic—and there are lots of picnic tables scattered throughout the parklike setting. A typically shallow, cascading stream makes for a fun spot for kids to splash, although the water's a bit chilly. After crossing the stream on the bridge, the 1-mile walking trail meanders through mango, monkeypod, and exquisite rainbow eucalyptus trees. This is an exceptionally peaceful place—good for yoga and meditation—that is, unless the resident roosters decide to crow.
