- Ride Prompton CCW, starting at the boat launch or the dam. This is a big ride because there's a huge lake in the middle. Trails are pretty easy to follow. Of the three trail systems, this is probably my favorite.
- Ride Merli CW, hitting all of the blue trail spurs, which are the best. You'll probably get screwed up at the new horse barn, and a few more times. That map is REALLY old.
- Ride Moosic however you want - lots of options.

It's not Monday but on Wednesdays there is a group ride at Moon Lake Park. Ride forms outside the main gate and usually leaves around 6:15. Mostly singletrack with plenty of rocks, roots, and obstacles thrown in. Just google Moon Lake for directions.
Parking for the FS ride is on "Carverton road" at the pumping station gas line area. If you Google it follow it till you see the gas line crossing Carverton Road... Please note there are roughly 5 miles of mt biking trails on that side of the park, and other trails there not open to mt biking. All other trails in the park are not open to mt biking. They do patrol, so beware of that fact. Moon Lake is a better choice on Wednesday nights.
