Wailua Falls
The double waterfall from the Fantasy Island credits, zero hiking required.
Maʻalo Road dead-ends at the guardrail view and the falls do the rest. Come early for the light and fewer tour vans. It's part of Wailua River State Park, which moved to paid entry for out-of-state visitors in February 2026, card only. Stay behind the rail... the scramble to the base is how rescues happen.
