Monroe's Munson Park is in the southeast corner of Michigan and about 15 miles north of Toledo, Ohio.
There are 2 loops to ride, and both are twisty and relatively flat. They make for a great recovery ride or a place to take new mountain bikers. Because they have no big hills they are also fun in the winter when there is snow on the ground.
The singletrack dries fairly slowly, so be careful if there have been rain or snowmelt recently.
To get to the trail, drive in the main park entrance. Follow the paved road until it turns to a gravel parking lot. Continue back until the gravel road forms two loops for parking where you'll park. You'll see soccer fields to the right (east) of you now. There is a field in between the parking area and the woods. Follow the grassy field east along a plowed field to your left (north) until it stops.
You'll see a well defined dirt path to your left (north) - follow these tracks. After you get past the first tree line, the trail turns left and heads towards a large section of woods. You'll find a trail (Orange Loop) cut into the brush with a noticeable trailhead sign.
The south-western section of woods is tight, twisty and slower going. As soon as you get up to speed you slow down to make another tight turn. The northeastern portion of the woods are straighter, easier, and can maintain speed much better (More like Island Lake).
With the additional two-track and rails-to-trails type surfaces, this is a great place to bring the entire family to ride.
