Back now on the western side of Kauai, sunny Polihale Beach is where your group will put in for landing if you had kayaked the Coast.  Your tired arms and perhaps sunburned faces serve as proof that you've completed a difficult journey that only a small number of adventure travelers have taken. Polihale Beach (the westernmost beach in the U.S.) connects with neighboring Barking Sands Beach to form 17 miles of pristine white sand and effectively Hawaii's longest beach.
