Kalalau Trail made National Geographic’s World’s Best Hikes: 15 Classic Trails. Here’s what their writer Peter Potterfield had to say:
Ke’e Beach to Kalalau Valley
Round-Trip: 22 miles, 3 to 5 days
When to Go: May to September for drier weather; April or October for more solitude
The finest coastal hike in the world, this rugged route through Kauai’s impressive Nā Pali Coast will challenge you physically with tropical heat and steep trails, and scare you with exposure on muddy slopes. But after a day of slogging 11 miles through the fluted cliffs above surf that crashes like howitzer fire on the coast below, you are rewarded with a view of the impossibly serene mile-long arc of golden Kalalau Beach along the shimmering Pacific. The Kalalau Valley itself holds fairy-tale waterfalls and lush tropical jungle, well worthy of exploration, but the highlight is camping right on the beach, with the Western Pacific before you, reflecting the setting sun.
Insider Tip: It’s hot, and you’ll be tempted, but don’t even think about cooling off with a swim at Hanakapi’ai Beach on the way in. All those small, makeshift memorials are erected in the memory of hikers who thought they might enjoy wading in and were immediately swept out to sea by the violent rips.
