Basically the long drive you'll end up doing will be from Polihale state park to Waimea Canyon and then to Kee state beach park thru Princeville. You can't take the Elise to Polihale as the roads are unpaved and have large potholes and tire ruts. Rental cars take a lot of beating even the SUV's? Barking sands area was always dry and Princeville area was the wettest when I have been there vacationing. I always look for job when I am over there and have no luck.
Hopefully the locals could shed more light on driving adventures.
