Hiking on Kauaʻi

On the North Shore, at the end of the highway, you'll find the Nā Pali Coast's famous Kalalau Trail and its shorter version, the 2-mile Hanakāpīʻai Trail. The full Kalalau is the island's most challenging hike, taking physical and logistical preparation months before you arrive. Hanakāpīʻai is a four-mile round-trip waterfall hike many visitors do to get a taste of what the longer trail is like. This is the rainy side of the island, so expect mud — and it still gets hot and humid, so bring plenty of water and sun protection. I'd base yourself in Hanalei or Princeville for these hikes, so your room is close by when you finish, exhausted. Kalalau is a destination trail: choose it only if you're in excellent condition and planning your whole trip around the adventure.

The Kalalau Trail is one of the most beautiful hikes in the world. It's also one of the most dangerous — Outside magazine has named it among the 20 most dangerous hikes on earth. Matthew Wu fell to his death on the Hanakāpīʻai Falls trail. Zachary Rose fell near Mile Marker 7. Daniel Foster died after a fall into Kalalau Valley near the end of the 11-mile trail. In May 2026, a 37-year-old visitor from California was found unconscious on the trail and died at the hospital. A December 2024 drowning at Hanakāpīʻai Beach claimed a 32-year-old hiker from Alaska. These are not rare exceptions — they're a consistent pattern.

The trail is really two experiences. The first two miles to Hanakāpīʻai Beach are moderate, but slippery after rain — which, on the Nā Pali Coast, is most of the time. The beach itself is a separate danger: powerful rip currents, sudden large waves and no lifeguards make Hanakāpīʻai one of the most hazardous swimming spots in Hawaiʻi. Do not enter the water here under any circumstances. The sign at the beach tracking deaths is for real.

Past mile 2, it becomes backcountry — narrow paths, steep drops and slick sections that demand extreme care. Crawler's Ledge, a narrow path carved into a near-vertical cliff face, requires full attention and sure footing. Stream crossings can turn impassable without warning. Heat, dehydration and underlying medical conditions show up repeatedly in rescue reports, especially in summer. There's no cell service, and helicopter rescue is weather-dependent and can take days.

None of this means you shouldn't go — it means you should go prepared. Train before you arrive: hike uphill with a loaded pack, build endurance, get comfortable with exposure and heights. Pack a first-aid kit, duct tape and blister treatment; your feet will take a beating and your toenails may not survive. Hydrate constantly. Carry a satellite communicator and know your emergency protocols before you leave the trailhead. The people who think Kalalau is easy are the ones who get into trouble.
