Waimea Canyon State Park is a 1,866-acre state park on the west side of Kauai, and it holds the gorge Hawaiians call the Grand Canyon of the Pacific.
The canyon runs roughly 10 miles long, about a mile wide, and more than 3,600 feet deep, with rust-red cliffs, green valleys, and the 800-foot Waipo’o Falls.

What Is Waimea Canyon State Park?
Waimea Canyon State Park is a 1,866-acre Hawaii state park protecting a gorge carved over millions of years by the Waimea River and the collapse of the volcano that built Kauai.
The red colour of the canyon walls comes from iron in the old basalt, slowly rusting in the open air.
People call it the Grand Canyon of the Pacific, a line often credited to Mark Twain, though he toured Hawaii in 1866 and never set foot on Kauai.
The canyon needs no borrowed fame: on a clear morning, the layered walls shift between brick red, burnt orange, deep green, and soft lavender.
After rain, thin ribbon waterfalls appear along the cliff faces and vanish a day later, so Waimea Canyon State Park never looks exactly the same twice.
Great Hawaii Tour recommends Waimea Canyon State Park as the single best half-day trip on Kauai’s west side, paired with Kokee State Park above it.
The Lookouts Along Waimea Canyon Drive
Waimea Canyon Drive (Highway 550) climbs from the town of Waimea to the canyon rim, and the lookouts line up like beads on a string.
Allow about 40 minutes to drive from Waimea town to the last lookout without stops, and most of a day once you start stopping.
Waimea Canyon Lookout — Mile Marker 10
The main Waimea Canyon Lookout sits at mile marker 10, about 3,400 feet up, and gives the widest view straight into the heart of the canyon.
Waipo’o Falls is visible across the gorge from here on a clear day.
The lookout reopened in early 2026 after a long closure for safety railing and walkway improvements, so the platform and parking are fresh.
It is the busiest pullout on the drive, so arrive early.
Red Dirt Waterfall — Mile Marker 5
Stop at mile marker 5 for the Red Dirt Waterfall, a small cascade over bright red earth that makes a quick, easy photo stop.
Pu’u Ka Pele and Pu’u Hinahina Lookouts — Miles 13 to 13.5
Pu’u Ka Pele Lookout, around mile 13, shows a different angle on the canyon’s layered walls.
Pu’u Hinahina Lookout, at mile 13.5 and about 3,640 feet, gives a long cross-section view of the gorge winding toward the ocean.
On a clear day, Pu’u Hinahina is also the best spot to see Niihau, the privately owned Forbidden Island, about 17 miles offshore.
Kalalau Lookout and Pu’u o Kila — Miles 18 to 19
Past the canyon, the road enters Kokee State Park and climbs to Kalalau Lookout at mile 18.
Kalalau Lookout looks straight down into the lush, fluted cliffs of Kalalau Valley and out to the Na Pali Coast.
Pu’u o Kila, at the end of the road around 4,000 feet, gives an even broader sweep of Kalalau Valley and is the trailhead for the Pihea Trail.
Clouds often hide these upper lookouts by late morning, so visit them first if the sky is clear.
Hiking in Waimea Canyon State Park
Waimea Canyon State Park has trails from a ten-minute stroll to a thigh-burning descent into the gorge.
Wear shoes with real grip, because the red dirt turns to slick clay when wet, and carry more water than you think you need.
Canyon Trail to Waipo’o Falls
The Canyon Trail to Waipo’o Falls is the headline hike at Waimea Canyon State Park.
It runs about 3.2 miles round trip, with around 800 feet of elevation change, and takes most people two to three hours.
The trail follows the canyon rim to the top of Waipo’o Falls, an 800-foot, two-tiered waterfall.
You cannot see the falls full-on from the top, but the pools above the falls and the canyon views make the hike.
The trail is rated moderate, though the last stretch is steep and eroded, and it gets very muddy after rain.
Cliff Trail and Iliau Nature Loop
The Cliff Trail is a short, easy spur off the Canyon Trail, about a tenth of a mile, leading to a railed overlook with a great canyon view.
Mountain goats are often seen clinging to the slopes below the Cliff Trail overlook.
Near mile marker 9, the Iliau Nature Loop is an easy, flat ten-minute walk through native plants with another solid canyon viewpoint.
Both are good options for families or for stretching your legs without committing to a full hike.
Kukui Trail
The Kukui Trail is the serious hike at Waimea Canyon State Park, for experienced, heat-tolerant hikers only.
It drops roughly 2,000 feet down into the canyon over about 2.5 miles each way, to the Wiliwili campsite on the canyon floor.
Going down is the easy part, and the climb back out in the afternoon sun is a genuine test, so start early and carry plenty of water.
Kokee State Park, Above the Canyon
Do not turn around at the canyon: keep climbing into Kokee State Park, where the landscape turns into cool, misty highland forest.
Kokee Lodge is the only real stop for food, restrooms, and a gift shop up top.
The lodge restaurant is open Monday to Friday from 10 a.m. to 4:30 p.m. and weekends from 9:30 a.m. to 4:30 p.m.
The Kokee Natural History Museum next door is free to enter and worth ten minutes to understand the geology, plants, and birds you are looking at.
Camping in Kokee State Park is closed for improvements through spring 2027, so plan Waimea Canyon State Park as a day trip.
Great Hawaii Tour tip: pair the canyon lookouts in the morning with lunch at Kokee Lodge, then descend to Waimea town for the afternoon.
How to Reach Waimea Canyon State Park, Hours, Fees and What to Bring
Getting There
Drive west from Lihue Airport on Kaumualii Highway (Highway 50) to Waimea town, then turn right onto Waimea Canyon Drive (Highway 550).
From Lihue Airport, plan about an hour and 25 minutes and roughly 42 miles to reach Pu’u o Kila Lookout at the top.
From the Poipu resort area, the drive is about an hour and 15 minutes.
A second road, Kokee Road (Highway 552) out of Kekaha, merges with Highway 550 partway up.
There is no gas station once the road starts climbing, so fill your tank in Waimea or Kekaha first.
Cell service is spotty or non-existent through the canyon and the high-elevation trails.
Hours and Fees
Waimea Canyon State Park is open daily during daylight hours, with no gate and no advance reservation for day use.
Hawaii residents enter and park free with a valid state ID.
Non-residents pay $5 per person for entry, and children 3 and under enter free.
Non-residents also pay $10 to park a standard vehicle, and one payment covers both Waimea Canyon State Park and Kokee State Park for the day.
Pay at the self-service kiosks in the main parking areas, and keep the receipt on your dashboard for the lookouts higher up.
Best Time to Visit
The drier months, April to October, give the clearest views of Waimea Canyon State Park and the driest trails.
The canyon is beautiful all year, and even on rainy days the wet rock colours deepen.
Go in the morning: aim to reach the first lookout by 9 or 10 a.m., before clouds build and roll in by early afternoon.
The rim sits around 3,400 to 4,000 feet, so temperatures run roughly 20 degrees cooler than at the beach — bring a light jacket.
What to Pack
Bring water, snacks, sunscreen, and a rain jacket, because the weather changes fast up top.
Wear sturdy shoes with grip for uneven, muddy trails.
Check the DLNR park notices page the morning you go: Waimea Canyon State Park and Kokee State Park were closed for about two months after Hurricane Lowell and Tropical Storm Nolo, and reopened for day use on November 7, 2026, with reduced services.
