What's with Rainbow Falls? Just above town, the Wailuku River pours over the lip of a lava cave into a wide green pool, and on a clear Hilo morning the mist throws a rainbow across the whole scene. Hawaiians call the place Waiānuenue — "rainbow seen in water" — and in the old stories the cave below was a dwelling place in Hawaiian tradition. Reach it early, before the tour vans, when the sun is low and the spray is bright, and you'll see exactly how the falls earned both their names. It is the easiest wonder to find in Hilo, and one of the loveliest in all Hawaiʻi.
Our Hilo logo carries the same emblem every Merlin Classics Hawaiʻi place wears — the hibiscus, above "Hawaiian Kingdom · Est. 1795," the year of unification under Kamehameha, printed in a worn, hand-pressed black and white. The hibiscus is the islands' mark, the through-line that ties Hilo to every other Hawaiʻi place we make — a nod to the aloha that defines them. What makes this one Hilo is everything around it: the bay, Rainbow Falls on the Wailuku, and the rain-green mountains behind the town.
Why People Visit Hilo
Hilo offers the most authentic, culturally rich side of Hawaiʻi Island — waterfalls, gardens, markets, and deep Hawaiian heritage, all in a relaxed bayfront town. Visitors come for the rainforest scenery and the easy access to volcanoes and coast, and stay for the unhurried, welcoming feel of a real town rather than a resort strip. From the morning rainbows at Waiānuenue to the gardens along the bay, it rewards a slow pace. It is green, genuine, and beautiful in every season on the bay.
