You can see Door County from your car, from the water, hiking through a great State Park, or you can bike Door County, or rent a moped or segway - you can see it all from a unique perpective.
Imagine biking the Sunset Trail in Peninsula State Park - magnificent! You can bring up your own bikes and scotters or you can rent one right here. Some of the rental palces for bikes carry great lines like Trek!
Also, the rental palces sell outdoor gear and biking equipment, can tune upi your bike or make a repair. Enjoy your time!
