good place to ride a bike, even a road bike with bags and to much stuff.
Do your self a favor and visit 3rd beach near La Push.
Lot of places to get off your bike up there. You dont want to ride the Lady of the Lake to Stehekin?
Northern tier passes through Twisp on hwy 20, best bet for a skinny tire bike
