USE CAUTION - KNOW BEFORE YOU GO! The recent ice storm on March 29, 2025 and subsequent wind events have left many downed and damaged trees across the Mio Ranger District of the Huron-Manistee National Forests that have interrupted recreation opportunities on motorized and non-motorized trails. Crews are actively working to clear trees and debris from Forest Service roads and trails. Visitors should expect down trees and other debris on trails and roads – Please slow down and use caution. Access to areas may be limited on the Forest. This may impact the ability of first responders, such as ambulance and fire first responders, to respond to an emergency. Hikers, equestrians and motorized trail users can locate affected trails on our website at or call the Mio Ranger District Office at (989) 826-3252.

About
Mack Lake ORV Campground is the largest campground on the Mio Ranger District, featuring 42 campsites with direct access to the Mack Lake Trail System. The campground sits on a 175-acre lake of shared private and federal ownership, surrounded by rolling jack pine plains that provide excellent wildlife viewing opportunities. An embedded day-use area within the Beaver Loop offers picnic facilities, a swimming beach marked with buoys, and carry-in boat access for fishing and paddling. Anglers can target sunfish, perch, and walleye. The campground is a popular destination for ORV trail riders, with the trailhead for the Mack Lake Trail System starting within the campground. Riders can explore easier sections near Maltby Hills or challenge themselves at Bull Gap Hill Climb. The trail system mostly features 0-10% grades with some short 30% grade sections. The trail is open to highway-legal ORVs 50 inches or less in width. Sites include picnic tables, campfire rings, and lantern posts. Two loops, Warbler and Beaver, accommodate both reservable and first-come, first-served sites. The campground is gated during the off-season.
