Field Notes: Backpacking the Kalalau Trail
Your Guide to Kauai’s Napali Coast
The Kalalau Trail on Kauai’s Napali Coast is a world-renowned adventure, and for good reason. This 22-mile round-trip hike weaves through lush valleys, towering cliffs, and pristine beaches, delivering awe-inspiring views that make every step worth it. If you’re looking to combine adventure, natural beauty, and a bit of grit, this hike is for you. Here’s everything you need to know about tackling this unforgettable journey.
WHAT MAKES THE KALALAU TRAIL SO SPECIAL?
Stretching from Ke’e Beach to Kalalau Beach, the Kalalau Trail offers some of the most dramatic coastal scenery in the world. Along the way, you’ll cross five valleys, trek through dense jungle, and conquer narrow cliffside paths that hover high above the turquoise ocean. The highlight? Kalalau Beach, where golden sands meet lush green cliffs in one of the most breathtaking settings imaginable.
But this isn’t just a scenic stroll—it’s a demanding hike that tests your limits. With a total elevation gain of 6,177 feet, it’s no wonder the Kalalau Trail is often considered one of the most challenging (and rewarding) hikes in Hawaii. It’s even been featured on Outside Magazine’s list of the “20 Most Dangerous Hikes in the World.”
