This route has paths for all skill levels. It is a single track and has lots of turns. Most of it is in the woods but some comes out into a meadow. One flaw is that you can hear the cars and highway most, if not all of the time. It is fun and if you want some challenges they are definately there.
From the cities take Highway 52 south into Rochester. Take US 14 east exit (it comes after US 14 west). Go through a ton of stop lights and it will be on the right. Their are multiple starting areas to different difficulties of trails. One trail head starts at the picnic shelter on the west end of the park, this one will lead you to the rest of the trails there.
