Yellick & Suasco - Stirrup Brook Mountain Bike Trails

You can access the Yellick & Suasco trails by parking on Boundary St. in Northborough. This is mostly an out and back route, although there are a couple lollipop loops you can create where the trails branch off behind the Algonquin High School. Take the trail out of the dirt lot on Boundary St. You’ll ride along the perimeter of a farmer’s field before heading back into forest, where you’ll find a few old vintage cars that were left to rust away. Once you reach the top of this climb, you’ll notice the trail branches. You should take the right branch down a hill, through another farmer’s field and back into the woods, and will eventually end on Rt. 20. Head to the west on Rt. 20 (your right from this direction) and cross the road where you see a pull off area with Jersey barriers a short distance up the road, and the entrance to the Stirrup Brook Trail is behind the pull off.
