On the Na Pali Coast (north side of Kauai), I hiked 4 miles in to reach the Hanakapi'ai Falls. Brought my Phantom 2 Drone in a pre molded backpack and let her fly. Terribly unstable vortex made this my hardest flight yet. Was challenging to stabilize the drone at any moment. This is the raw, unedited footage taken on a GoPro Black.
