A good collection of xc style singletrack. The best option is to find the trail that goes to the top of the hill, along the ridge for a while then drops down the other side. It's a fun ride in both directions.<br />

Unsure of the total mileage. Will edit as I explore more.
Take I-89 to Exit 7. Make a right onto Paine Tpke and another right onto Crosstown Rd. Go under the highway and make a left onto Paine Tpke S, then right onto Brookfield Rd. The parking area is about one mile up the road, on the right.
