Tour de Dalhousie (64km)

Updated: Feb 9, 2022

Location: Purdon Conservation Area, Lanark County, Ontario


Estimated Gravel Time: 90%

Full Route Map:


Distance: 63.5km (39.8 miles)

Suggested Tire Width: 38mm or wider

Amenities: While the route itself includes no re-supply options, there is a small public swimming area on the south-western shores of the Mississippi River off Elphin Maberly Rd. Upper Park Lake and Bower Lake off of Ranger Camp Rd. also provide access for swimming. In addition, a small restaurant can be found at the Sylvania Campground close to the end of the route.

Route Description:

Craving a leg day? This route has you covered with close to 1000m of climbing in just under 65km, as riders navigate the hilly single lane gravel and unmaintained that dominates the area surrounding Dalhousie Lake. Needless to say, a minimum 1:1 gear ratio is recommended.

Umphersons Mill Road South

Beginning from the Purdon Conservation Area, head north along the 8th Concession. This dirt road eventually narrows to sandy single-lane gravel as the route joins Umphersons Mill Road South and climbs steadily to Ranger Camp Rd.

Ranger Camp Rd.

Here, the route makes a left, following this classic stretch of unmaintained as riders continue to climb for approximately 8km, past Upper Park Lake and Bower Lake, as well as several (at times busy) Crown Land campsites before reaching Lavant Mills Rd. The loop then follows this section of unmaintained south, descending for the most part all the way to Gemmills Rd.

Gemmills Rd.

Follow Gemmills Rd. west on a series of steep climbs and fast descents to Adams Rd. South. Having ridden this route counter-clockwise, riders will now have the benefit of descending on this rugged stretch of unmaintained (which would otherwise require a bit of hike-a-bike) to Elphin Maberly Rd.

Adams Rd. South

Upon reaching the bottom of the descent, follow the pavement south to the shores of the Mississippi River and a small public swimming area. From here, the route continues south-west on Gully Rd., a quiet stretch of scenic pavement for just under 4km, before eventually making a left onto the K&P Trail, which parallels Township Road 49. This section of the rail trail climbs steadily and sees a mix of nicely maintained doubletrack combined with short sections loose rock, potholes and flooded quagmire, before eventually exiting on Clarendon Rd.

The next 17km of gravel, including Clarendon Rd. and Kingston Line, consists of a series of punchy ups and downs, before transitioning from gravel to quiet pavement via Highland Line, as the route snakes its way east towards McDonald’s Corners. After McDonald’s Corners, the route follows Watsons Corners Rd. for 3km and while this road can see a bit more traffic, riders will have the benefit of a quick descent to the 8th Concession. From here, the route ascends steeply back to the Purdon Conservation Area and the start of the route.

Awesome route, thanks Adrian. Did it yesterday, no dogs.

NOTE: A section of the K&P between Mississippi Station and Robertsville Road is closed, fenced off and signed No Trespassing by the landowner. The reroute is the 509 from Mississippi Station to Robertsville Road or, if you want to avoid a few mud puddles, to School Side Rd./Clarendon Rd. at Ardoch/Clarendon Station where you rejoin the route.

CAUTION - Mad white good sized dogs along Gemmells Rd. The rough location is in this Strava segment : https://www.strava.com/segments/32435538 I came around a corner and 2 dogs (I believe from a property) attacked and positioned themselves on each side of my bike. One bit my leg, a few teeth when in quite deep. I fortunately was able to out run them but it was an effort to get in front of them. I will be OK - I am more worried if someone would wipe out in the process. I will get a hold of the local police and see what can be done. In the mean time, be careful if you really must use this route.

This is a really nice route! It is the first gravel bike ride I did after putting on some gravel tires on my old Trek 520. I put Vittoria Terrino Dry tires (700x35) and they were, for the most part, fine. I would not go any narrower, however. Though the total ascent is in the order of 1000m, in reality it is a lot of down and up - the speed gained going down quite often helped going up. There were, however, some climbs where I definitely needed the smaller of 3 plateaus on my front derailleur - there were still quite a few spots where 1st gear was required.


Awesome site BTW - so useful for people like me…
