Edge of the World: Hiking the Kalalau Trail Along Kauai’s Napali Coast
An 11-mile spine of ridges, jungle, and remote beaches—prepare for a humbling, incredible coastal trek
You round a bend and the ocean drops away—an impossible, prismatic valley opens below, carved into steep green teeth that plunge to surf and foam. Wind tugs at your pack and the trail, narrow and time-worn, presses you forward along a spine of volcanic ridge. That first, unquestionable view arrives less like a photograph and more like a small revelation: the Napali Coast is not a place that patiently waits for you to admire it. It dares you to move through it.
Trail Wisdom
Start before dawn
Begin early to avoid midday heat, secure parking at Ke‘e, and give yourself buffer time for muddy sections.
Permits for overnight stays
A Kalalau camping permit from Hawaii DLNR is required for any overnight in the valley; check availability well ahead of your trip.
Filter your water
Bring a reliable filter—stream water can be clear but contaminated after rain events.
Be cautious around streams
Do not attempt river crossings after heavy rain—flash floods happen quickly and without much warning.
