LetÃ¢â‚¬â„¢s get muddy. LetÃ¢â‚¬â„¢s rev up our engines and attack more than 3,100 miles of the best ORV trails in the State of Michigan. Here two-track, twisty single-track, rocky hill climbs and soggy mud bogs welcome dirt bikes, quads and four-wheelers. So letÃ¢â‚¬â„¢s load up the GPS, because the stumps, whoops, logs, brush and sand hazards that dot the lightly groomed trails await our knobby tires. Inviting us to enjoy the muddy side of Pure Michigan.
