Island twice, and Kauai FTW.
My wife and I rented a car and explored the entire island. I purchased and read this entire book, picked a bunch of places and explored all week.
My favorite thing was a big hike down Nu’alolo Trail and Awa’awapuhi Trail. Absolutely breath taking views, a little slice of heaven.
