The Crown Jewel: Hiking the Na Pali Coast
No discussion of Kauai hiking is complete without mentioning the Na Pali Coast. This legendary stretch of coastline on the island’s North Shore is inaccessible by road, making hiking one of the primary ways to experience its raw, untamed beauty. Imagine dramatic, fluted cliffs plunging thousands of feet into the turquoise Pacific, hidden beaches, and valleys dripping with waterfalls – it’s truly a sight to behold. Several movies, including classics like Jurassic Park and Pirates of the Caribbean, have captured glimpses of this magic, but nothing compares to seeing it with your own feet on the trail.
The Kalalau Trail: An Epic Pilgrimage
Considered one of the most incredible – and demanding – hikes in the world, the Kalalau Trail is the ultimate Kauai adventure for experienced trekkers.
| Feature | Detail |
| Difficulty | Difficult |
| Length | 22 miles (35.4 km) out & back |
| Elevation | ~6,177 ft (1883 m) gain |
| Highlights | Unparalleled coastal views, Kalalau Beach, waterfalls, river crossings |
| Permit | Required (Book well in advance) |
This trail is not for the faint of heart. It traverses high above the ocean, crossing rugged terrain, navigating sheer drop-offs, and involving potentially treacherous river crossings prone to flash floods. But the rewards? Simply incomparable. You’ll hike through lush valleys, witness powerful waterfalls, and finally reach the secluded paradise of Kalalau Beach, a place only accessible via this trail or by sea. Camping permits are necessary if you plan to stay overnight, allowing you to fully soak in the majesty of this protected coastline. Remember, meticulous planning and preparation are essential for this challenging but life-changing trek.
Hanakapi’ai Falls Trail: A Taste of Na Pali Magic
If the full Kalalau Trail seems too daunting, the Hanakapi’ai Falls Trail offers a substantial dose of Na Pali beauty within a challenging day hike. This trail follows the first two miles of the Kalalau Trail to Hanakapi’ai Beach before turning inland.
| Feature | Detail |

| Highlights | Coastal views, Hanakapi’ai Beach, 300 ft Hanakapi’ai Falls, jungle trek |
| Permit | Required (Book well in advance) |
The initial coastal section delivers stunning views of red rock paths contrasting with the deep blue ocean and vibrant green jungle. After reaching the beach (use caution near the water due to strong currents), the trail heads inland, following a stream through dense bamboo forests and requiring some stream crossings. The payoff is the magnificent 300-foot Hanakapi’ai Falls cascading into a beautiful pool – a perfect spot to rest and marvel before the return hike. Expect steep inclines, muddy sections (especially after rain), and navigating over tree roots. It’s a strenuous but incredibly rewarding journey into the heart of a Na Pali valley.
Kalepa Ridge Trail: Short, Steep, and Spectacular Views
For jaw-dropping views of the Kalalau Valley and Na Pali coastline without the commitment of the full Kalalau Trail, the Kalepa Ridge Trail is an unofficial but popular option for experienced hikers.

| Caution | Unofficial, narrow, steep drop-offs, slippery when wet |
Starting near the Kalalau Lookout in Koke’e State Park, this trail descends along a narrow ridge. The path can be challenging, with sheer drop-offs demanding careful footing and a head for heights. It’s crucial to avoid this trail during or after rain, as the mud can make it extremely hazardous. However, on a clear day, the vistas are simply epic, offering a bird’s-eye perspective directly into the iconic Kalalau Valley. This is a high-risk, high-reward hike best suited for confident adventurers.
Exploring Waimea Canyon & Koke’e State Park
Known as the “Grand Canyon of the Pacific,” Waimea Canyon offers a different but equally stunning Kauai landscape. Think vast gorges painted in hues of red, orange, and green, with waterfalls carving through the ancient volcanic rock. Adjacent Koke’e State Park provides access to numerous trails exploring both the canyon rim and the lush forests and ridges above the Na Pali Coast.
Waipo’o Falls Trail (Canyon Trail): Views from Above
This popular trail offers fantastic perspectives into Waimea Canyon and takes you to the top of the impressive 800-foot Waipo’o Falls.

| Highlights | Sweeping Waimea Canyon views, jungle section, top of Waipo’o Falls |
Don’t expect to see the full cascade from the bottom on this trail; instead, you’ll journey through forest and emerge near the headwaters of the falls, enjoying panoramic canyon vistas along the way. There’s even a smaller pool above the main drop where you can cool off. It’s a great way to immerse yourself in the canyon’s grandeur without an overly strenuous climb, making it perfect for sunrise or sunset viewing.
Awa’awapuhi Trail: Ridge Hiking to Na Pali Vistas

Remember, the hike back is mostly uphill! It’s best tackled in dry conditions as the trail can become muddy.
Nualolo Ridge Trail: A Challenging Na Pali Loop
Often combined with the Awa’awapuhi Trail via the Nualolo Cliff Trail (check trail status) for a longer, challenging loop, the Nualolo Ridge Trail offers its own incredible views and diverse terrain.

Starting often from the Pu’u O Kila lookout or connecting trails, this hike takes you deep into a high-elevation swamp teeming with unique flora and fauna adapted to the misty, wet conditions. The extensive boardwalk system helps protect the fragile environment (and keeps your feet drier, though mud is still likely). The trail culminates at the Kilohana Lookout, which on a clear day offers stunning views down into the Wainiha Valley, stretching all the way to Hanalei Bay on the North Shore. Be prepared for potentially wet and chilly conditions, even on sunny days elsewhere on the island.
Exploring the East & South Shores
While the North Shore and Waimea Canyon garner much attention, Kauai’s East and South Shores offer delightful hikes with their own unique charm, often featuring coastal walks, jungle streams, and accessible waterfalls.

Tips for Hiking on Kauai
- Check Conditions: Weather can change rapidly. Always check the forecast and trail conditions (mud, stream levels, closures) before heading out. Websites like the Hawaii Division of State Parks are valuable resources.
- Permits: Be aware that popular trails, especially the Kalalau Trail and Hanakapi’ai Falls, require permits booked well in advance. Plan accordingly!
- Footwear: Sturdy hiking boots with good traction are essential, especially given the prevalence of mud and slippery rocks.
- Water & Snacks: Carry plenty of water, more than you think you’ll need, and high-energy snacks. Dehydration can set in quickly in the tropical climate.
- Sun Protection: Use sunscreen, wear a hat, and sunglasses, even on cloudy days.
- Rain Gear: A lightweight rain jacket is always a good idea.
- Insect Repellent: Mosquitoes can be present, especially in jungle areas.
- Navigation: While many trails are well-marked, having a map, compass, or GPS device (and knowing how to use them) is wise, particularly for less-maintained or remote trails.
- Leave No Trace: Pack out everything you pack in, stay on marked trails, and respect the ‘aina (land).
Kauai’s trails offer an incredible opportunity to connect with nature in its most spectacular forms. From the demanding cliffs of Na Pali to the depths of Waimea Canyon and the gentle paths along the coast, adventure awaits around every corner. Choose your trail, prepare wisely, and get ready for an unforgettable hiking experience on the Garden Isle!
