This route is fine except for the section where it takes the "Yellow Outer Loop" - this area should be avoided unless trailwork is done - trails are overgrown/boggy in that area as is. Just cut over to the "Landlocked Forest Loop" for that section if you want to follow this route.
We hope you've been enjoying Trailforks!
