GPS Downloads

  • KML/KMZ files can be opened in Google Earth, and many smartphone apps.
  • GPX files can be opened by most GPS software apps when KMZ cannot. Note, GPX files do not contain custom colours and icons that we use on our maps; all tracks and icons will appear the same colour and styles. We recommend using KMZ instead of GPX if possible.

The files below include data for only this specific area. For all of our Trans Canada Trail data for the entire province (including features, campsites and alternate routes), download our BC.kmz master file (1.2 MB)

Visit our GPS & Navigation page for instructions of how to use your smartphone as a GPS device (even when outside of data coverage) or how to import data to your Garmin unit.

About the Route: 

The Dewdney Trail is a historic hiking/equestrian trail that follows the route used by miners and settlers in mid-19th century British Columbia. However, only a few sections of the trail remain in operation as recreational trails, including this short portion between Santa Rosa Road (Christina Lake) and Highway 22 (Rossland), which is registered as a non-motorized recreational trail by the BC Ministry of Forests (MFLNRO, Recreation Sites and Trails BC Branch). This portion of the Dewdney is 37.5 km in length and generally is an overnight hike.

Note: Our GPS tracks for the Dewdney Trail are not considered to be 100% accurate. Use at your own risk. You will notice up to three separate GPS tracks braiding along the Dewdney trail on our map; they are all from separate sources - and we have posted all three, not really knowing which (if any) are the most accurate. One is from the Ministry of Forests, while another is from OpenStreetMaps (an open source online map). A third that travels just the eastern 1/3 of the trail is supplied by the Kootenay Columbia Trails Society. We welcome your feedback - and invite anyone to send us their own GPS tracks to help us improve the accuracy. Again, please note that all tracks are "use at your own risk" (see our Disclaimer above for more details).

The Dewdney Trail is crossed many times along its length by its successor, the Cascade Highway, which was opened in 1922 and allowed travellers to drive motor vehicles over the Monashee Mountains. This gravel roadway has been largely replaced by the Crowsnest Highway, so is mainly used by recreational users - and makes a suitable route for adventure cyclists or support vehicles (4WD recommended) for hikers. It is a 72 km drive with countless hairpin turns and stunning views - but is known to be quite dry and dusty, so carry plenty of water. Our GPS track should be completely accurate.

Connection Points to the TCT: 

The western terminus of the Dewdney Trail (between Christina Lake and Rossland/Trail) connects to the Trans Canada Trail at the intersection of the Columbia & Western railway and Santa Rosa Road. The connection point is approximately just south of Santa Rosa Road, on the east side of the rail trail. The trail climbs and crosses Santa Rosa Road further uphill after about 500 metres. For those using the old Cascade Highway to travel to Rossland, simply fillow Santa Rosa Road instead.

The eastern terminus of these alternate routes is lcoated in downtown Trail and connects to the proposed Trans Canada Trail at the intersection of Bay and Farwell. Of course, the Trans Canada Trail route on this side of the Columbia River is still proposed; the trail route requires the construction of a bridge over the river which has yet to be built. For now, to connect to the Trans Canada Trail from this point, cross over the Columbia River on Victoria Street (Highway 3B) using the main highway bridge.

Trail Highlights and Developments: 

The Dewdney Trail was originally a 720 km (450 mi) trail that served as a major thoroughfare in mid-19th century British Columbia, running from Hope to Fort Steele. The trail was a critical factor in the development and strengthening of the newly established British Colony of British Columbia, tying together mining camps and small towns that were springing up along the route during the gold rush era prior to the colony's joining Canadian Confederation in 1871. The route's importance and urgency was prompted because many new gold finds were occurring at locations near the US border that were much more easily accessed from Washington Territory than via any practicable route from the barely settled parts of the Lower Mainland and Cariboo. Today, approximately 80 percent of the former trail has been incorporated into the Crowsnest Highway - the portion running between Christina Lake and Rossland is one of the last sections remaining in operation, though as a recreation trail.

Parking & Staging Areas

There is parking available where Santa Rosa Road intersects the Trans Canada Trail above Christina Lake on the western end. 


There are two campsites located on the trail - the first at Trout Creek at the 9.7 km mark, and the second at the Santa Rosa Recreation Site at the 22.1 km mark - located 300 metres off the trail.

Shopping & Provisions

There are no supplies or provisions along the Dewdney or Cascade. Shop for supplies on the western end in Grand Forks. Limited provisions are available in Christina Lake. Rossland and Trail are good places to provision on the eastern end.

Report a Trail Closure


Trail maintenance issues are the responsibility of the Trail Steward, which is either the trail owner or a group given authorization to perform maintenance work. Trails BC is a trail steward for a very limited number of trail segments on the Trans Canada Trail; unfortunately, if a major trail issue occurs along the Trans Canada Trail, there is often very little we can do about it - but we can try to pass on the information to the trail steward, if one exists.

Information such as a precise location (GPS waypoint), photo, as well as your contact information is extremely helpful to ensure the problem is accurately reported.

AGAIN, DO NOT USE THIS FORM TO SUBMIT NOTICES ABOUT TRAILS THAT ARE NOT PART OF THE TRANS CANADA TRAIL. We will simply delete the submission and it will not be posted or passed on to anyone. If you need to report a closure on such a trail, please determine the trail owner or operator and send a notice to them.

Would it be unwise to continue through the closure or blockage? You may add more detail in your report.
Please enter your trail closure report. Include a GPS location or a detailed description of its precise location.
