This is one of the hot spots for mountain biking in the Twin Cities. This is a good, challenging singletrack trail in the middle of a forest with plenty of sharp, twisty curves, several hill climbs, and some wild descents. Unfortunately, it's closed from October 15 through May 1.
How to get there:
Take Burnsville Parkway east from Highway 35W past County Road 11. The park is on your right. The mountain bike entrance is on Burnsville Parkway about 1/3 mile east of County Road 11. (Note that the west entrance is not open to mountain bikers.) There are signs that indicate where the trail is, along with maps.
Lots of technical singletrack, and it's a nice thrilling ride.
