I would appreciate your experience on "must do's, must sees". We'll be 10 days on our bikes cycling the perimeter, 2 days in Hilo, and 3-4 days in Kona. Really enjoy poking around in the local culture, food, etc.
Make a point to go see the tropical side of the big island and pack a swim suit. Tons of natural falls right by the road. Just stop and swim w/ the locals. It's awesome there's a little sandwich shack in Hilo that has good eats too. about 8 years ago
