This is Mackinac.

Witness the power of the creek harnessed to cut timber into lumber at one of the oldest industrial sites on the Upper Great Lakes. Smell the sawdust as sawyers demonstrate the pit saw method of cutting lumber, then feel the power of the creek used to cut timber inside the reconstructed sawmill.
Join the Forest Adventure Experience, a guided trek that takes you into, above and through the northern Michigan forest. Scale the five-story Treetop Discovery Tower, taking in bird calls along the way. Brave the Forest Canopy Bridge, high above Mill Creek that explores the under story of the forest. Finally, fly like an eagle down the 425′ Eagle’s Flight Zip Line while spotting fish in the creek.
Join trained naturalists for engaging programs showcasing the North Woods, and then take time to explore the natural beauty of Mill Creek State Park, which has more than three miles of groomed hiking trails.
