Hilo is the wettest city in the United States, and everything people love about it — the waterfalls, the mist, the ferns growing out of century-old storefronts — is the rain's doing. This guide covers the old bayfront town and the fifty-mile sugar coast that unspools north of it, gulch by gulch, to the edge of Waipiʻo Valley.
Two tsunamis (1946 and 1960) leveled Hilo's waterfront, and the town rebuilt inland and modestly. What survived is one of the most intact early-1900s downtowns in Hawaiʻi — wooden storefronts, hand-painted signs, and a pace that has nothing to do with resort Hawaiʻi. Give it a full day, ideally a Wednesday or Saturday.
The corner of Mamo and Kamehameha, under the tents. Rambutan, apple bananas, warm mango bread, orchids for a few dollars. Come before 9 a.m. for the best produce and the fewest cruise-ship crowds.
Cash is easiest; bring small bills.
A broad 80-foot falls on the Wailuku River, five minutes from downtown. The name means "rainbow seen in water" — arrive on a sunny morning around 9–10 a.m. and the mist usually delivers one. Continue upriver to Boiling Pots for churning lava-rock pools.
Free, no hike required — lookout is steps from parking.
A 24-acre Japanese garden on the bay, laid out in the early 1900s to honor sugar-era immigrants — stone lanterns, arched bridges, banyans. Walk the footbridge to Mokuola (Coconut Island) for the classic view of the bay with Mauna Kea behind it on a clear day.
Best light is early morning, before the trade-wind clouds build.
Housed in a bank building that survived both waves, and staffed with docents who sometimes lived through 1960. A sobering hour that explains why the bayfront is parkland today — and why the town feels the way it does.
Pairs well with a walk down Kamehameha Ave afterward.
At the end of Kalanianaʻole Ave past Banyan Drive: a small black-sand pocket with calm, reef-protected water and resident honu (green sea turtles). Carlsmith Beach Park, just before it, has grassy lawns and ladder-entry lagoons that are perfect with kids.
Give turtles at least 10 feet — it's the law and the custom.
Where Mauna Kea astronomy meets Hawaiian voyaging and navigation, told side by side. The planetarium is excellent, and it's the best indoor answer to a truly torrential afternoon. Kaumana Caves — a raw, free lava tube up Saddle Road — is the adventurous alternative.
Bring a real flashlight per person for Kaumana.
North of Hilo, the Hawaiʻi Belt Road rides the shoulder of Mauna Kea across old sugar-plantation land — one green gulch after another, each with its own bridge, stream, and story. The green mile-marker signs are how locals give directions out here, so that's how this guide is organized. Budget a half day one-way; a full day if you stop everywhere.
Leave the highway for the old mango-shaded coast road. Hawaiʻi Tropical Bioreserve & Garden drops through a ravine to the bay (paid, worth it); the free Onomea Bay trail just past it reaches the shoreline in ten minutes.
Honomū is a one-street plantation town of wooden storefronts — get taro or lilikoʻi butter mochi at Mr. Ed's Bakery on the way up. The state park loop trail (0.4 mi, paved) passes through bamboo and torch ginger to ʻAkaka Falls, a single uninterrupted 442-foot ribbon. This is the one unmissable stop on the coast.
Under the tall highway bridge, where Kolekole Stream — the same water that just fell over ʻAkaka — meets the sea. A local picnic-and-rope-swing spot. The ocean here is rough and not for swimming; the stream pool is the draw.
A leaf-shaped lava peninsula pounded by open-ocean surf, with a memorial to the students and teachers lost when the 1946 tsunami struck the schoolhouse that stood here. Wild, beautiful, and usually nearly empty. The little train museum back on the highway tells the sugar-railroad story.
Tex Drive In has been frying malasadas — Portuguese doughnuts, best hot and lilikoʻi-filled — since 1969; watch them made through the window. Honokaʻa's main street below is the largest town on the coast: the restored 1930 Honokaʻa People's Theatre, antique shops, and good plate lunch.
The road ends at a lookout over the Valley of the Kings: a mile-wide amphitheater of 2,000-foot cliffs, taro fields, and a black-sand river mouth. Boyhood home of Kamehameha I and one of the most sacred places on the island. Access into the valley is restricted — check current rules before planning more than the lookout, and treat the place, and its residents, with care.
Hilo's food is the sugar era's living legacy — Japanese, Portuguese, Filipino, Chinese, and Hawaiian traditions layered into plate lunches, mochi, and poke. Almost everything below is under twenty dollars.
A working fish auction house on the bay since 1907. Get a poke bowl at the counter and eat it across the street in Liliʻuokalani Gardens.
$ · lunchA tiny downtown shop famous for fresh mochi and manju — the strawberry mochi (a whole berry wrapped in white bean paste and rice dough) sells out. Go early; cash only.
$ · take-outThe self-proclaimed home of the loco moco, serving it since the 1940s: rice, hamburger patty, fried egg, brown gravy. Order at the window, eat at the picnic tables.
$ · all dayChocolate-dipped macadamia shortbread made in a spotless glass-walled factory you can watch. The gift-box answer for everyone back home, with generous samples.
$$ · omiyagePancakes wider than the plate, kalua pig, laulau, and portions built for cane workers. Come hungry or come with someone to split with.
$ · breakfastThe mandatory Hāmākua stop (see the drive above). Hot malasadas, plain or filled — lilikoʻi is the correct answer.
$ · any hour it's openIt rains most days — usually in passing showers, heaviest overnight and in late afternoon. Mornings are your friend: do waterfalls and the coast drive early, museums and food later.
Pack a light rain shell and shoes that can get wet. Umbrellas are optional; locals mostly just wait it out under an awning.
You need a car. Hilo International (ITO) has rentals and puts you ten minutes from downtown; from Kona side, Saddle Road (Hwy 200) crosses the island in about 90 minutes.
Gas up in Hilo or Honokaʻa — there's little in between on the coast.
Hilo's hotels cluster on Banyan Drive along the bay — older properties, unbeatable location. B&Bs and vacation rentals upslope in neighborhoods like Wainaku add rainforest quiet.
For the coast, Honokaʻa has small inns that put Waipiʻo at your doorstep for first light.
Streams and waterfall pools can flash-flood with rain you can't see upslope — if the water rises or browns, get out. Never turn your back on the ocean at Laupāhoehoe or Kolekole.
Many places on this coast, Waipiʻo above all, are culturally significant or residential. Take nothing, stay on marked paths, and let closed mean closed.
