The LaCrosse VELO club deserves much credit for the job they did here. Trails are well built. Singletrack is tight, twisty, and full of log obstacles. The hills are sure to make you sweat a little bit. There is a map in the parking lot to show you the recommended route.
From I-90 take exit 5. Go south into LaCrosse. Stay on that road, it turns into Losey blvd. Go about 4 miles to Main st. Take a left on Main and go straight up the bluff. Main turns into Bliss Rd. Go all the way to top of hill and make left on county rd. FA. Go one mile and park in gravel lot next to weather station.
