Canadian Rockies Gravel Traverse

The Canadian Rockies Gravel Traverse links the southern end of the Canadian Rockies at Waterton Lakes National Park north to Jasper, following a corridor of forestry roads, back-country fire roads, and gravel highway alternatives that stays close to the Continental Divide for most of its length. This is not a signed, curated route — it is a line drawn through a landscape where the roads happen to exist and the passes happen to be rideable.

The terrain is unambiguously alpine. The route crosses multiple passes above 2000m, traverses sections of the Great Divide Trail corridor, and passes through or alongside four UNESCO World Heritage national parks: Waterton Lakes, Banff, Yoho, and Jasper. The scenery is at a scale that becomes almost numbing after a week — turquoise glacial lakes, limestone peaks at 3000m, and river valleys that go on for 50km without a building in sight.

The technical challenges are varied. Some forestry roads are smooth graded gravel; others are rough doubletrack with embedded rock and drainage bars that require concentration on the descent. The passes are mostly rideable — the Continental Divide rarely exceeds 2400m in the accessible sections — but the approach gradients are sustained and the surfaces deteriorate near the summit on the BC side. River crossings are the unpredictable element: snowmelt in June and early July raises the streams that cross unbridsged forestry roads, and some sections require a route adjustment.

Grizzly bears are present throughout, and actively so. The Canadian Rockies have one of the highest densities of grizzlies in North America. Bell your bike, carry bear spray on your person, not in your bag, and know what to do if an encounter occurs. This is not theoretical risk management — encounters on forestry roads are documented every year.

Services are sparse north of Canmore. The national park towns (Banff, Lake Louise, Golden, Jasper) provide full resupply, but the forestry road sections between them can be 80-120km without anything. Plan drops carefully and carry enough food for an extra day if a river crossing or mechanical forces a reroute.

Most riders take 16-20 days. The route rewards those who start in Waterton in late June when the passes are clear and finish in Jasper before the September shoulder-season weather turns.
