Hike Sleeping Giant Trail, Kauai: Complete 2023 Guide
Partied to no end, lay down for the night, and just couldn’t get up? Not a throwback to your college dorm days!
That’s the native legend behind the whimsical name, Sleeping Giant, for the Nounou Mountain, and you’re most likely to agree to a giant’s resemblance from the eastern side of Kauai, especially from Kapa’a.
Folklore apart, the Nounou mountain offers two exciting trails for the avid hiker, up to the chest of the giant, and for the adventurous few, to the chin, nose and forehead, for amazing, 360-degree views of the eastern part of Kauai.
The West Sleeping Giant Trail is shorter, less of a climb (you start from a higher elevation), more shaded, and, in my opinion, much prettier!
The East Sleeping Giant Trail joins the West Sleeping Giant Trail after a steeper, longer hike, and both trails share the last 1/2 mile or so.
The two Sleeping Giant Trails are among the best Kauai hikes near Kapa’a, on the eastern side of the island.
Let’s explore the two Sleeping Giant Trails virtually, and you can decide which one is more suited for you and your group!

Hike Sleeping Giant Trail: Fast Facts
Sleeping Giant Trail Difficulty
Both Sleeping Giant Trails are rated hard in difficulty.
The West Sleeping Giant Trail is the easier of the two, but can be the muddier one after rains.
While for the most part, both trails are moderately difficult, but there are sections on the trails that require some scrambling over rocks.
And if you decide to go past the picnic tables on the chest, the Sleeping Giant Trail is definitely hard, and you will encounter a roughly 70 degrees rock wall, but not perpendicular.
Sleeping Giant Trail Length
The West Sleeping Giant Trail length is about 0.9 miles for a total round trip distance of 1.7 miles on this out & back hike.
The East Sleeping Giant Trail length is about 1.6 miles for a total round trip distance of about 3.2 miles, so this hike is almost double the distance of the other trail.
If you go past the picnic tables, you’ll likely add about 1/2 mile to the above.
Sleeping Giant Elevation Gain
The Sleeping Giant Trails take you up to the Nounou mountain summit, so the trails involve steep grades.
The West Sleeping Giant trail elevation gain is about 700 feet, while the East Sleeping Giant Trail elevation gain is about 1300 feet, significantly more climbing.
Sleeping Giant Trail Time Taken
The West Sleeping Giant Trail takes about 1.5 to 2 hours at an average, while the East Sleeping Giant Trail takes about 2.5 to 3 hours.
What about Kids and Dogs on the Sleeping Giant Trail?
Dogs on leash are allowed on both the Sleeping Giant Trails.
Though I’ve seen families with older kids on both the trails, I would not recommend taking younger kids on the hikes, especially past the picnic tables.

Sleeping Giant (Nounou) Trail Information
Both Sleeping Giant Trails are hikes through the Nounou Forest Reserve to the Nounou mountain summit.
I found the trails well-marked, with 1/4 mile markers along the trail, and junctions clearly signposted. The two Sleeping Giant trails are part of the Hawaii’s Na Ala Hele Trail system and are regularly maintained.
Your main concern should be to get back to the same spot that you started from – so take the appropriate trail back at the junction.
West Sleeping Giant Trail to Junction Point
The West Sleeping Giant Trail starts along a residential home fence (please keep your voices low so as not to disturb the local residents), and quickly converts to a mud trail through a forest.
You come almost immediately to a beautiful Cook pine grove, with the picturesque pine trees towering over you.
Cross the Kuamoo Trail junction (stay left), and start climbing up the mountain, but on a well-shaded forested trail with mostly non-native invasive trees like the African albizia that were planted to control erosion.
About .75 miles into the trail, you will come to a bench with Aloha engraved on it, and the first open views from the mountain side, with views of the Kong mountain across the plains and the ocean.
A few minutes later you will reach the junction of the Nounou East Trail and the Nounou West Trail continuation.
East Sleeping Giant Trail to Junction Point
The East Sleeping Giant Trail starts with a series of switchbacks climbing up the Nounou mountain, through the Nounou Forest with mostly non-native trees like ironwood, silk oak and fruit trees like breadfruit, guava and strawberry.
Every now and then, you can catch glimpses of the Sleeping Giant’s head from the trail, your ultimate destination. You get some great views along the trail of the east coast of Kauai and Wailua.
There is a small junction where you need to stay right, if you take the other path you go up to a rock wall with some pink spray paint which is pretty slippery, and will have to retrace your steps.
At about the 1.5 mile marker, you will lose most of the shade and come to the junction of the Nounou West Trail (right) and the Nounou Trail Shelter (left). Turn left onto the common trail towards the picnic tables shelter.

Sleeping Giant Trail – Common Section
You will come to two picnic tables with benches under a rain shelter roof. You are now on the giant’s chest, under his chin!
You are still in a forested area with trees like the koa haole, hala, and ti. You can also see many fruit trees with pretty red strawberries (edible and delicious!), guava, breadfruit, hala and others.
Head to the bench (with “Respect” carved on it), and admire the beautiful, panoramic views from this lookout.
This is the official end of the Sleeping Giant Trails, and most people turn back after enjoying the views and, maybe, a picnic.
For the thrill seekers and adventurous hikers, there are trails that take you further up, but note that these are fairly sketchy, with steep 100+ feet drops, and some scrambling up rocky paths / walls.
You are going along the ridge now, up the chin and nose.
A small side trail on the left takes you to a cave-like structure with two openings with spectacular views of Wailua, Kapa’a and the coast.
The trail to the nose and forehead ends on flat mud platform and a rocky outcropping. From this viewpoint you get fabulous 360-degree panoramic views.
You can expect to see the Wailua River, mountain peaks of Wai’ale’ale and Kawaikini on the west side, Makaleha mountains to the north, and the Pacific Ocean, Kapa’a and Wailua on the east.
Sleeping Giant Trail Map
The below Sleeping Giant Trail map shows the locations of the two trailheads and the trail destination.
The Wailua River State Park, one of the best state parks in Kauai, is a few minutes away with many exciting things to do with stunning waterfalls like the Wailua Falls, Opaeka’a Falls and Secret Falls, Wailua River and boat cruises, and historic sites.
Hawaiian Birds to Spot on the Sleeping Giant Trail Hike
Make sure you take a good pair of binoculars with you, the Sleeping Giant Trail hike is great to spot some beautiful Hawaiian birds, both introduced to the islands and some endemic birds (found nowhere else)!
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).
You’ll probably hear the white-rumped shama, before you spot them. They are the most skilled songbird in Hawaii, and frequent forest streams.
The ‘apapane, one of the endemic Hawaiian birds, can be spotted here among the native ohi’a lehua trees, feeding on the nectar from the tree’s pretty red or yellow flowers.
If you’re an avid birdwatcher, the Wailua River State Park with its waterfalls and river are a better spot to find these and other beautiful Hawaiian birds.
Refer to our detailed post on Hawaiian birds to identify and learn about these bird species, some endemic to Hawaii, and found nowhere else on the world!
Hawaiian Plants, Trees and Flowers on the Sleeping Giant Trail hike
The Sleeping Giant Trail is a forest hike on the lush, windward side of Kauai, with many common and easily identifiable Hawaiian plants, trees and flowers to look for!
On the Sleeping Giant Trail hike you’ll see iconic Cook pine tree groves, canoe plants like breadfruit (ulu) and ki (ti) brought by the ancient Hawaiians, hala trees (identifiable by tufted aerial roots), and the highly invasive strawberry guava fruit trees, among many others!
