Na Pali Coast State Wilderness Park Hiking Guide
The Na Pali coast on Kauai's northwest shore is among the most visually striking pieces of American public land. Seventeen miles of sea cliffs rising up to 4,000 feet from the Pacific Ocean, cut by narrow valleys, and pierced by waterfalls visible from the water. The State of Hawaii has managed this 6,175-acre wilderness park since 1983, with the Hawaii Division of State Parks administering access through a permit system. The official park page is the primary source for current permit availability and conditions.
What defines this park more than any other aspect is inaccessibility. There is no road here and there will not be one. The cliffs make road construction physically impossible for most of the coast. That means the 11-mile Kalalau Trail, kayak approach from Polihale State Park, or boat and helicopter tours are the only ways to experience the Na Pali coast directly. This constraint produces both the park's wild character and its logistical complexity. The permit system exists because the trail and the valley are finite, and demand has consistently outpaced capacity.
What to Expect
The terrain is genuinely demanding. The Kalalau Trail runs along the cliff faces at various heights, alternating between narrow ledge sections with significant exposure, valley descents into stream crossings, and open coastal ridge walking with views of the Pacific. It was built and maintained by the ancient Hawaiians who inhabited these valleys; the modern trail follows paths worn over centuries of use.
The coast breaks into five valleys between the Ke'e Beach trailhead and Kalalau Valley: Ke'e, Hanakapi'ai, Hoolulu, Waiahuakua, and Kalalau. Hanakapi'ai (2 miles in) is the only valley accessible to day hikers without continuing the full trail. The valleys between 2 and 8 miles are legally off-limits to camping, though some attempt it; rangers patrol the area and fines are significant. Kalalau Valley, at the 11-mile point, is the only legal camping destination.
The ecology of the Na Pali valleys is a mix of introduced species (strawberry guava, Java plum) in the lower areas and more native forest higher up. The valleys receive substantial rainfall; Kalalau averages around 40 inches per year, but the inland ridges are far wetter. Waterfalls appear throughout, fed by the high ridges above. Spinner dolphins are regularly seen offshore, and Hawaiian monk seals occasionally rest on the beaches.
The trail's condition varies by season and by rainfall. Some sections are clay-based soil that becomes extremely slippery when wet. The cliff-edge portions carry genuine fall risk in poor conditions. Trekking poles provide meaningful stability on the steep switchbacks, particularly after rain.
Best Trails
Kalalau Trail
11.0 mi, Point-to-Point, Strenuous
The full Kalalau Trail starts at Ke'e Beach at the end of Kauai's north shore road (Highway 560) and ends at Kalalau Beach, 11 miles and several thousand feet of vertical gain and loss later. The first 2 miles to Hanakapi'ai Beach represent the easiest and most-traveled section, but the permit requirement applies throughout.
Miles 2 through 6 are the most technically demanding: narrow cliff paths, sustained elevation changes, and sections where a misstep onto the cliff face would be fatal. This portion is not suitable for inexperienced hikers in wet conditions. Miles 6 through 11 open into broader ridge terrain before descending into Kalalau Valley.
The trail is one-way by permit structure; hikers must start and end at Ke'e Beach (unless approaching by kayak from Polihale). Most hikers doing the full trail carry camping gear and spend at least 2 nights at Kalalau before returning.
Hanakapi'ai Falls Trail
4.0 mi, Out-and-Back from Trailhead, Moderate-Hard
From the Ke'e trailhead, this route walks the first 2 miles of the Kalalau Trail to Hanakapi'ai Beach, then turns inland for 2 more miles up the valley to a 300-foot waterfall. The valley section involves multiple stream crossings that can be impassable after heavy rain; check conditions before committing to this extension. The waterfall itself drops into a deep pool and is one of the most rewarding destinations on Kauai for the effort involved. Day hiking permit required as of 2026.
Hanakapi'ai Beach Trail
2.0 mi, Out-and-Back, Moderate
The first 2 miles of the Kalalau Trail to Hanakapi'ai Beach give a strong sense of the Na Pali terrain and cliff scenery without the full commitment of the extended hike. The beach appears in summer when sand accumulates; in winter, waves typically cover it completely. Do not enter the water here. The currents at Hanakapi'ai Beach are among the most dangerous on Kauai; there is a sign at the beach listing drowning deaths. Day hiking permit required.
When to Visit
May through September is when the Kalalau Trail is most reliably hikeable. Summer trade winds moderate temperatures and sea conditions allow kayak access from Polihale (a 17-mile paddle by sea). The beaches are visible rather than submerged by winter swells.
October through April brings north and northwest swells that pound the Na Pali coast with surf exceeding 20 to 30 feet in major storm events. The cliff sections of the trail remain technically open, but the conditions make the beach sections at Hanakapi'ai significantly more dangerous, and the overall experience is harder and wetter. Kayak access is effectively closed from November through March in most years.
There is no "off-season" at Na Pali in the way that benefits a visitor seeking solitude. The permit cap limits hiking numbers throughout the year, and summer permits are the hardest to obtain. If you have flexibility, shoulder season dates in May or September often have better permit availability than July.
Getting There and Logistics
The trailhead is at Ke'e Beach at the end of Highway 560, approximately 7 miles from Hanalei and 40 miles (1 hour 15 minutes) from Lihue Airport (LIH), the main Kauai airport. The parking area at Ke'e Beach is small and managed separately from the trail permit. Parking reservations are required at the Ke'e Beach lot as of 2026 and available through gostateparks.hawaii.gov alongside the hiking permit.
There is no entrance fee beyond the permit cost. As of 2026, hiking permits cost $10 per person per day; camping permits are $20 per person per night. These fees and structures may change; verify current pricing at gostateparks.hawaii.gov before booking. Note that Hawaii state parks are not covered by the America the Beautiful Pass, which applies only to federal lands.
Overnight camping at Kalalau requires carrying everything in and out. There are composting toilets at Kalalau but no potable water, no fire rings, and no trash service. Treat all water from the valley stream before drinking. A bear canister or hang system is required for food storage; feral goats and pigs in the valley are attracted to food and can damage gear. Check the checking conditions before you go resource for pre-trip research tools.
The alternative to hiking is a boat or helicopter tour from the south shore. Boat tours departing from Port Allen reach the Na Pali cliffs and some sea caves in about 2 hours. Helicopter tours offer aerial perspective on the entire coast. Neither requires a permit and both are viable options for visitors who cannot obtain trail permits or are not physically suited to the hike.
For another Kauai experience requiring less logistical effort, Waimea Canyon State Park on the island's west side is accessible by car and offers dramatic canyon scenery on a separate permit-free set of trails.
Planning Tips
- Book permits the moment the reservation window opens. As of 2026, the window opens 30 days in advance for day hiking and overnight camping. Set a reminder. They go fast.
- The trailhead at Ke'e Beach has no services. Bring everything from Hanalei or Princeville, including snacks, sun protection, and at least 2 liters of water per person for the shorter hikes. Many hikers carry more for the full trail.
- Shoes matter. The clay sections of the trail become genuinely dangerous when wet. Hiking sandals or lightweight trail runners are insufficient for the full Kalalau; trail shoes or boots with traction are what many experienced hikers choose.
- Flash flood risk is real in the valley sections. If rain is heavy and sustained upstream, do not attempt the Hanakapi'ai Falls stream crossings. People have drowned here.
- The 10 essentials for hiking list applies in full. Add a dry bag for electronics and camp gear, since ocean spray and rain are constant on the exposed sections.
- If your permit date arrives and conditions look dangerous (high surf, storm warnings, flash flood alerts), do not proceed. Permits are time-limited and the state does not currently offer refunds, but the cost of a lost permit is far less than the consequences of a bad decision on these cliffs.
The Na Pali coast exists in the condition it does because visitors have largely treated it with care. Follow Leave No Trace principles on every section of the trail, especially in the valley and at Kalalau Beach, where trace accumulation from campers is an ongoing management challenge.
