This is probably the most famous hike in
Kauai. The trail goes for 11 miles and leads you to Na Pali
Coast; the views along the way are simply beautiful. One
needs a permit to go past the first 2 miles (it is assumed
that you'll be camping if you go farther). At the end of the
trail lies Kalalau Beach and above it the beautiful valley
that you can see from the top of Waimea Canyon Drive at the
Kalalau Lookout.
