The Interlake Pioneer Trail (aka Prime Meridian Trail) is near Warren and Stonewall. Only about 2 miles East of Rubber Ducky campground. The trail starts near Argyle and runs all the way to Fisher Branch. That's a total of approximately 100KMs in one direction! We only covered about 10KM of this trail last year and came across cyclists, runners, ATV riders etc... Easy family riding.
