2 Best Sights in The East Side, Kauai

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 usually a peaceful place, but pay attention to the weather as the stream can flood quickly.

Nestled next to Wailua Marina along the mighty Wailua River, this 30-acre botanical and cultural garden offers a glimpse of distinctive foliage, including 20 types of fruit trees, a bamboo rain forest, and tropical lagoons. Enjoy a stroll along a mile of pathways. It's a popular spot for wedding receptions and other large events, and its luau is one of the island's oldest and best.
