Cycling - mountain biking and bicycle touring - is a fun thing to do on a Northwoods family vacation. Ride rolling bike trails that wind through the woods. Cycle flat track along crystal clear lakes. Pedal converted rail beds. Expend energy while having fun. Spot birds and animals. Take in the scenery. Picnic, fish and swim. With over 100 miles (160 km) of bike trails and a plethora of paved, lightly traveled roads family cycling in the Wisconsin Northwoods is an adventure on two wheels.
