Take a fascinating hike through history in the Plum Lake Hemlocks Forest State Natural Area. Explore the Milwaukee Road Railroad, state-leased land and the people that lived in this area over a century ago and walk in their footsteps. This is an off-trail, moderately-strenuous four to five mile hike with one wetland crossing. Bring a lunch and water. Masks are required for this program. Participants must drive themselves to the trailhead (directions will be sent in advance). Space is limited. Register by October 1st.
