Great place for mountain biking in Madison, really makes good use of one of the largest hills in the southern part of the town. Mostly Cross-Country type riding, however, there is one large and very steep hill (downhill type) with 3 moderately sized jumps. The large downhill takes about 45 seconds to bomb down, but is great fun with a few rock beds and banked turns incorporated in.
The recommended route to take to get to the large hill is to ride in on the path coming off of the road until you see a large Tee-Pee on your right (just off to the side of the trail, impossible to miss.) after this, follow the trail to the right and start climbing the hill =)
To get to the cross-country portion, keep straight after the tee-pee and continue going straight until you pass out of the yellow-grass, climb a moderate hill, and the foliage changes to pines. From there, you will intersect with a main trail system.
