Best Waimea Canyon Hikes, Kauai: Easy To Hard Trails – 2024
Stunning red-colored walls with contrasting emerald-green valleys and vegetation. Deep valleys with rivers and streams winding gracefully through the valley floors. Amazing waterfalls cascading over steep, towering cliffs.
Waimea Canyon is all the above and more! The most prominent geological feature in the interior of the island of Kauai, Waimea Canyon is a must-explore destination on every Kauai visitor’s bucket list!
Waimea Canyon is huge, spanning 13 miles long by 1.5 mile wide by 2,500 feet deep. No wonder it is one of the best places to visit in Hawaii!
Waimea Canyon sprawls over two different Kauai state parks: Waimea Canyon State Park and Koke’e State Park. You can use the same entrance fee and parking fee to visit both these adjacent sister parks.
And the best way to explore Waimea Canyon is on your own two feet, hiking the Waimea Canyon trail along the rim and deep into Waimea Canyon.
Hikes to view Waimea Canyon cater to hikers of all abilities, from easy, family-friendly hikes for kids, beginners, seniors and pregnant women, to hard, strenuous hikes meant for the experienced hikers in top physical condition!

Best Waimea Canyon Hikes, Kauai
1. Waimea Canyon Lookout Trail Hike
Struggling for time? The Waimea Canyon Lookout Trail, not really a hike at 0.1 miles roundtrip, is your quickest option to fabulous views of Waimea Canyon.
As one of the easiest Waimea Canyon hikes, this is a trail you will appreciate if you have members in your group in wheelchairs or kids in strollers.
The bulk of the lookout trail paved concrete and is accessible for most wheelchairs and strollers, but note that there are stairs to the upper viewing decks.
You can expect stunning views of Waimea Canyon and the surrounding landscape from the lookout, which is at an elevation of 3,400 feet.
Look for the 800-foot Waipo’o Falls, the Alakai Swamp on the uplands above the canyon and Po’omau Canyon created from the swamp water, Wai’ale’ale and Kawaikini (highest peaks on Kauai), and the Waimea River (base of the canyon).

2. Iliau Nature Loop Trail Hike
The Iliau Nature Loop Trail is one of the best easy Waimea Canyon hikes, family-friendly and kid-friendly, and short at 0.4 miles roundtrip distance.
If you are carrying kids on backpacks or have seniors or pregnant women, this trail is ideal since you have minimal climbing (about 100 feet elevation change).
The Iliau Nature Loop Trail takes you on a mud trail through some forested sections with native vegetation, but also along the rim and offers amazing views of the Waimea Canyon.
The Iliau Nature Loop trailhead is along Koke’e Road (Highway 550) about 3/4 of a mile beyond the 8 mile marker (see the best Waimea Canyon hikes map below).
3. Waimea Canyon Trail to Waipo’o Falls
The Waimea Canyon Lookout and the Iliau Nature Loop Trail are relatively easy Waimea Canyon hikes, meant more for beginning hikers.
The Waimea Canyon Trail connects with the Waipo’o Falls Trail to provide a 3.0 roundtrip distance hike of easy to moderate difficulty, and is probably the one of the best Waimea Canyon hikes for most hikers wanting a real hike along the rim.
The Waimea Canyon Trail to Wapo’o Falls is one of the best Koke’e State Park hikes and one of the best Kauai waterfall hikes.
You reach the trailhead by continuing on Koke’e Road to the Pu’u Hinahina Lookout (between mile markers 13 and 14) (see the best Waimea Canyon hikes map below).
The Waimea Canyon Trail to Waipo’o Falls starts through a dense tropical rainforest, continues along the Waimea Canyon rim with fabulous views, and ends at the top of the 800-foot Waipo’o Falls that you saw from the Waimea Canyon Lookout.
4. Kukui Trail Hike (Hardest of the Waimea Canyon hikes)
Tired of hiking the Waimea Canyon rim and want to see what’s at the bottom?
The Kukui Trail, one of the hardest best hikes on Kauai, starts from the rim (use the best Waimea Canyon hikes map below) and takes you to the floor along the west side of Waimea Canyon.
With a roundtrip total distance of 4.5 miles and an elevation change of 2,200 feet, the Kukui Trail is one of the hardest Waimea Canyon hikes.
Named after the many kukui nut trees along the trail, the Kukui Trail starts off as a hike through a forest on dirt trail, with loose rocks. Pretty soon you will encounter steep switchbacks descending sharply down.
Along the hike you will get magnificent views of Waimea Canyon with contrasting red walls and lush green vegetation, see multiple waterfalls, and enjoy Waimea River at the floor of the valley.
Reserve a lot of energy and water for the challenging hike back up, a bit of slog!

Other Waimea Canyon Hikes
If you complete the best Waimea Canyon hikes listed above, and are looking for additional hikes in the area or to add onto an existing hike, you have many options.
There are two Waimea Canyon hikes at the bottom of the canyon, typically after the Kukui Trail hike down: the Waimea Canyon River Trail hike (10.4 miles round trip) and the Koaie Canyon Trail.
The Kohua Ridge Trail is a hike that starts on the other side of the canyon and along Kohua Ridge. It offers views of the west side of the canyon, unlike all the Waimea Canyon hikes described above.
There are multiple smaller trails, offshoots of the Waimea Canyon Trail and the Waipo’o Falls Trails like the Black Pipe Trail and the Cliff Trail. These are smaller hikes, some of which can be tacked onto the main hike, especially the Cliff Trail hike.

Hawaiian Birds to Spot on Waimea Canyon Hikes
Waimea Canyon trails are a great place to spot some of the pretty forest birds of Hawaii, some endemic to the island of Kauai, and not even found on the other islands!
Some of the common Hawaiian birds you can expect to see are the rose-ringed parakeet (a highly invasive bird species), the red-crested cardinal (pretty red-headed birds with a crest), and the warbling white eye (with a characteristic white ring around its eyes).
If you’re an avid birdwatcher, the adjacent Koke’e State Park is a better spot to find these and other beautiful Hawaiian birds, especially on some of the park’s best trails.
The ‘akikiki (Kauai Creeper) is found only on Kauai and mostly in the Alakai Swamp wilderness of Koke’e State park, and is critically endangered, with little protection to recent avian malaria disease carried by mosquitoes.

Hawaiian Plants, Trees and Flowers on the Waimea Canyon Hikes
You can spot many common and easily identifiable Hawaiian plants, trees and flowers on the forest trails of Waimea Canyon.
Refer to our detailed post on Hawaiian plants to identify and learn about these species, some endemic to Hawaii, and found nowhere else on the world!
The kukui nut tree or the candlenut tree was brought to the Hawaiian islands by the ancient Hawaiians in canoes, and the oil from the nut was used to light their stone lamps.
We saw many kukui nut trees on the Kukui Trail, and hence the name!
The Iliau Trail is named after the iliau plant, endemic to Kauai.
In spring and summer, you’ll see pretty flowers along the trails, including ohi’a lehua red or yellow flowers and beautiful yellow kahili ginger flowers.
Hiking Gear Checklist
Many of Hawaii’s hikes are demanding, make sure you are well equipped and well prepared. Here’s what we typically take with us:
- Water Bottle: I hate plastic bottles, and with opaque bladders you can’t see if it is moldy inside. We use this Hydro Flask water bottle – light, stainless steel, wide mouth (you can add ice), with double-wall vacuum insulation (greatly refreshing for hikes in summer). You can also get it with a Flex Straw Lid!
- Hiking Shoes: My preferred hiking shoes are the medium range Merrell Moab 3 Waterproof Hiking Shoe (men’s, women’s, men’s mid), great for Hawaii’s trails through mud and streams. My wife loves her high-end Salomon X Ultra 4 GTX Hiking shoes (men’s, women’s), also waterproof.
- Sunscreen: Hawaii’s sun can be harsh. Avoid sunburn with sunscreen compliant with Hawaii’s 104 Reef Act. The Sun Bum Original SPF 50 Sunscreen Spray, moisturizing with Vitamin E, is our go-to when we travel to Hawaii. Apply liberally and regularly!
- Trekking Poles: Great for hikes that involve climbing, both going uphill and downhill, and on trails that are wet, muddy and slippery! Improve your footing with this collapsible, high-end Black Diamond Trail Cork Trekking Poles, available for men and women.
- Headlamp: Planning a sunrise or sunset hike? Hiking in the dark is no fun, especially on many of Hawaii’s rainforest or ridge hikes. We love these two headlamps: the budget Black Diamond Spot 400 Headlamp and the premium Petzl Actik Core Headlamp, with many features.
Hiking Safety Tips
Hiking in Hawaii can provide opportunities to get up close to its beautiful landscapes and allow you to observe local flora and fauna.
But hiking in Hawaii can also pose challenges you may not have encountered elsewhere. It is important to keep safety considerations uppermost in your mind as you plan a hike in Hawaii and as you are on the trail.
Here are some tips that may help:
- If it’s your first time hiking in Hawaii, or you are a beginner hiker, you may want to consider a guided hike with an experienced local hiking guide. A local guide can help you pick a trail and hike with you.
- Heed any posted signs at the trailhead or along the trail.
- Minimize the potential for trailhead vehicle break-ins by locking belongings in the trunk, out of sight, and carry valuables with you.
- Hike with a buddy or in a group, and stay together as you hike.
- Leave information about the trail you plan to hike, and your expected time of return, with a trusted contact.
- Obtain adequate information about the trail from official sources so you know your route, trailhead, etc. ahead of time. Download a trail map + bring a printed copy.
- Carefully assess if a trail is suited to your hiking skill level and physical capability. Each island has a wide variety of trails from which to pick.
- Get the latest weather forecast before you head out. Weather can change with little warning, so keep your eye on the weather as you hike.
- Beware of flash floods in streams and gulches. Avoid crossing swollen streams.
- Stay on the trail to minimize the potential for getting lost.
- Start early and plan your turnaround time such that you can get back to the trailhead while it is still light out.
- Call for emergency assistance if you are lost or injured.
- For more detailed hiking safety information, seek guidance from Na Ala Hele, the official resource for Hawaii hikers.
