Over roughly five million years, the Waimea River carved a canyon that stretches about 10 miles long and drops more than 3,500 feet deep — earning it the nickname “Grand Canyon of the Pacific.” This guide covers the best hiking trails and roadside lookouts on Kaua‘i’s west side, with practical advice for planning a visit — including an important update on current access.
Waipoo Falls drops roughly 800 feet into Waimea Canyon — a double-tiered cascade visible from multiple lookouts along the rim.
| Trail | Difficulty | Distance (round trip) | Time | Highlight |
|---|---|---|---|---|
| Canyon Trail to Waipoo Falls | Moderate | 3.4 miles | 2–3 hours | Upper rim of 800‑ft double‑tiered waterfall |
| Awaawapuhi Trail | Strenuous | 6.4 miles | 4–5 hours | Sheer 2,500‑ft drop into Na Pali valleys |
| Cliff Trail | Moderate | 1.8 miles | About 1 hour | Canyon rim views, connects to Canyon Trail |
From Līhu‘e, it’s about a 45‑minute drive west on Kaumuali‘i Highway (Hwy 50) to Waimea town, then a winding climb up Waimea Canyon Drive (Hwy 550) to 4,000 feet. Gas up in Waimea — it’s the last station before the road rises. The canyon has several pull‑off lookouts, each offering a different perspective.
Waimea Canyon Lookout (mile 10.4) is the main stop, with direct views into the canyon’s widest section. On clear days, you can see Waipoo Falls spilling down the far wall. Continue to Puu Hinahina Lookout (mile 13.4) for a higher, broader view that on a clear day extends to the “Forbidden Island” of Ni‘ihau. Push on into Kōke‘e State Park (miles 15–18) for the Kalalau Lookout, where the 4,000‑foot view down the Nā Pali cliffs into Kalalau Valley rivals any aerial shot on the island.
Late morning offers the best light on the canyon walls. Afternoon clouds roll in from the north, so start early — the west side of Kaua‘i is the driest, but clouds can form quickly at elevation.
Canyon Trail to Waipoo Falls
The best hike in the canyon begins at the Pu‘u Hinahina parking area (between mile markers 13 and 14 on Hwy 550). The Canyon Trail is a 3.4‑mile round trip with about 750 feet of elevation loss on the way down, then a steady climb back. The trail ends at the upper rim of Waipoo Falls — a double‑tiered cascade that drops roughly 800 feet into the canyon below. You can’t see the main falls from the end because you’re above them, but there’s a small pool upstream surrounded by yellow ginger.
The trail gets slippery after rain, especially near the waterfall. Dogs are not allowed. It’s popular with families — older kids (8 +) usually do fine, but toddlers will find the climb back tough. Carrying a child in a backpack carrier makes the uphill stretch harder.
To reach the trailhead, park at Pu‘u Hinahina and follow the spur trail that connects to the Cliff and Canyon Trails. The total hike from the highway is about 4 miles round trip if you include the walk down Halemanu Road (the alternative 4WD access). Allow 2–3 hours at a steady pace.
Awaawapuhi Trail
For the most dramatic viewpoint on the island that doesn’t require a boat or helicopter, take the Awaawapuhi Trail. It starts near the Kōke‘e Museum and runs 6.4 miles round trip through dense forest to a narrow ridge with a sheer 2,500‑foot drop into the Nā Pali valleys below. The trail is strenuous — expect 4–5 hours, with steep sections and exposed edges. The payoff is a view that few visitors ever see.
Because of the distance and elevation, this hike isn’t suitable for young children or anyone with a fear of heights. Bring more water than you think you’ll need; there’s none at the trailhead or along the route. Start early to allow time for breaks and to avoid hiking back in fading light.
Practical Information
As of September 2026, Waimea Canyon and Kōke‘e State Parks remain closed until further notice due to Hurricane Lowell damage. Do not enter closed park areas — saturated soil, damaged trees, and unstable edges can be hazardous even after weather improves. Check the official Waimea Canyon State Park page and the Nā Ala Hele trail system for current trail status before planning your trip.
When the parks are open, hours are sunrise to sunset daily. There is no admission fee for the canyon itself, but Kōke‘e State Park charges a $5 entrance fee per nonresident adult and $10 per vehicle for parking (as of August 2026, per the state parks division). Fees and operating conditions can change — confirm on the official park page before you go.
What to bring: water (nothing available past Waimea town), layers — the top is genuinely cold at 4,000 ft (50s–60s°F common) — a rain jacket, and closed‑toe shoes with good grip. Download offline directions before you climb; cellular service is unreliable at many overlooks.
Safety: stay behind railings and well back from unprotected edges. Loose volcanic soil, wet grass, and hidden drop‑offs can make seemingly safe viewpoints dangerous. Never climb around a closure or step onto an eroded shoulder for a photo. If trails are open, choose a route that matches the slowest person in your group, and turn around before fatigue, rain, or fading daylight becomes a problem.
Before You Go — Waimea Canyon
Is Waimea Canyon open right now?
As of late 2026, both Waimea Canyon and Kōke‘e State Parks are closed due to Hurricane Lowell damage. The official park page and the Nā Ala Hele trail system are the only reliable sources for reopening updates. Do not rely on third‑party sites.
How much time do I need for a visit?
Plan at least a half day for the scenic drive and a few overlooks. Add a full day if you want to hike — the Canyon Trail alone takes 2–3 hours, and the winding road takes longer than its mileage suggests, especially with fog or full parking areas.
Can I hike with kids?
The Canyon Trail to Waipoo Falls is popular with families. Older kids (8 +) should handle it fine; toddlers will find the climb back steep. The Awaawapuhi Trail is too strenuous and exposed for young children. No dogs are allowed on any canyon trails.
If you’re planning a broader Kaua‘i trip, our island‑hopping itinerary weaves in the canyon alongside the south shore beaches and Nā Pali coast.
