If you're a hiker, you'll love this trail that hugs the rugged Na Pali. The hike is not easy, often crossing narrow and slippery ridgelines. But you'll be rewarded with spectacular views. You'll walk through a tropical forest, descend onto Hanakapiai Beach, climb up and down into Hoolulu Valley, then Hanakoa Valley. The final leg takes you into breathtaking Kalalau Valley, rippled with streams and waterfalls. There's camping on the beach at Kalalau.
