Route Description:

This loop caters to anyone looking for something a little different, as the bulk of the route forgoes gravel roads in favour of the ample single and double track located throughout the East Duffins Headwaters south of Uxbridge. Looking to shred? Ride your hardtail. Craving a little underbiking action? Take your gravel bike. Want to stick mainly to gravel roads? Follow the alternatives suggested in the route map. Looking for additional off-road goodness? Go explore one of countless side trails scattered throughout the route. The choice is yours!

As these are shared-use trails, please be respectful of other users and yield the right-of-way to hikers, horses and mountain bikers pursuing those elusive KOMs. In addition, as much of this route takes place on mild mountain bike trails, familiarize yourself with the basics of the International Mountain Bicycling Association rules before you go. Finally, please note that while this loop is only 72km long, given some of the mild technical sections, be sure to budget a bit more time to complete it.

Greenwood Conservation Area single track

Starting from the Greenwood Conservation Area trailhead, head north via some mellow single track for 2.5km to Concession 6. Continue briefly on pavement across Highway 7 and follow Paddock Rd. north to a dirt trail under the highway. Following the underpays, the route remains on asphalt for another kilometre or so to Sideline 12, and the loop’s first section of maintained gravel.

After a kilometre or so, make a right and follow a brief section of trail (a mix of abandoned paved road and single track) to Concession Road 8.

Concession Road 7, heading north to Glen Major Forest

Upon exiting the trail, make a right and continue on exposed farmland dirt for the next 7km to the Glen Major Forest trailhead. This next section of off-road riding includes an initial segment of slightly technical single track, featuring a number of exceptional hilltop lookouts. After approximately 2.5km, the loop joins the Great Trail portion of the route. Here the trail system becomes noticeably easier as it winds its way north to the East Walker Woods trailhead parking lot.

Cross Concession Road 7 as the route stays off-road, descending steadily on a section of wide double track to Durham Regional Road 21. Traverse the slightly busy road and remain on this non-technical portion of single track for the next 3.5km to Brookdale Rd. Given the relatively gentle nature of this section (and the lack of quiet roads nearby) no suggested alternatives to the main route are provided.

After a steep descent to Brookdale Rd., stay on the Great Trail as it meanders north and west for 5km to Elgin Park. Please note that the segment of the trail directly north of Brookdale Rd. is perhaps the route’s most technical, with several steep portions requiring a bit of hike-a-bike. Anyone looking to avoid this section are advised to continue on Brookdale Rd. to Concession Road 7, which rejoins the main loop prior to Crosby Street.

Caution ought to be exercised when riding the trail north of Brookdale Rd.

After stopping in Uxbridge, riders wind their way south on various suburban backroads to Elgin Park Drive. Here, the route enters the Countryside Preserve trail system for 3km to Rolling Meadows Rd., followed by some additional trail riding via Timber’s Tract. As the only viable alternative to this section of trail is a relatively busy road, no substitute to this mellow segment of single/double track is provided.

Timber's Tract

Upon exiting Timber’s Tract make a right and remain on quiet tarmac for the next 3.5km, past the Slabtown Cider Company, before entering the next section of trail via the Glen Major Forest trailhead. This section of trail is one of the route’s longest as it winds its way south-west for 5km on a mix of single and double track, before returning to pavement via Brock Rd.

Final section of single track through Glen Major Forest
Sideline 20 Rd.

After crossing the Uxbridge-Pickering Townline, stay on Brock Rd. as it heads south to the village of Claremont. Exit the village via Sideline 20 Rd. Here, the loop returns to well maintained gravel as it makes its way south to 7th Concession Rd. Head left and remain on dirt to Brock Rd., whereupon the route transitions back to pavements and descends quickly to Paddock Rd. Double back on Paddock Rd. as riders return to Greenwood Conservation Area and the start of the loop.
