Mallory Swamp ATV Trail
Featured Trail Near Mayo, FL!This area of the Mallory Swamp Wildlife Management Area has about 35 miles of designated ATV trails. The trails are better described as roads that are mostly wide and flat with some occasional loose sand. The main staging area is a grassy parking lot with some shade under a large oak tree but there are no other services and cell phone coverage is spotty.
Visitors should be careful when using a GPS tool for driving directions here because this method can take you through some backwoods roads that are narrow and overgrown or muddy, leading you a long way just to find a locked gate, especially if you are coming from the eastern or central part of Florida. The best way to reach the staging area we've found is to navigate to the town of Mayo first, then take SR-51 south to County Road 360.
The trails are open daily for riding except during hunting season which generally runs from September through April. Exact dates vary so call before you haul.
There is no fee but a daily use permit is required which simply means you will have to fill out one of the blue forms found at the kiosk at the main staging area (bring a pen).
