Waiānuenue (Rainbow Falls) & Boiling Pots
Both sit in Wailuku River State Park on Waiānuenue Avenue, a short drive from downtown. The 80-foot falls are named for the rainbows that form in the mist on many mornings. Farther upriver, the Boiling Pots are a chain of pools below Peʻepeʻe Falls that churn as if boiling, lined with columns of cooled basalt. You view both from lookouts. Neither area is safe for swimming.
