Forestry Trunk Road — Hwy 734 Blackstone Gap to Grave Flats (Alberta)
Blackstone River crossings and elk country solitude.
North of Nordegg, Highway 734 punches deep into country most people only see on a map. The Blackstone Gap to Grave Flats stretch is where the road earns its reputation — narrow shelf sections above the Blackstone River, creek crossings that vary wildly with snowmelt, and views across open meadows that make you question why you’d ever go back to pavement. Grave Flats itself is a broad alpine bench ringed by unnamed ridges where elk and moose outnumber vehicles by a comfortable margin. The Blackstone River crossing mid-route is the decision point: in June it’ll test your recovery gear, by late summer it’s a manageable wade.
This is a legitimate high-clearance route — a stock 4WD with decent all-terrain tires and a skid plate is the minimum. Lift and lockers help in wet conditions. The road is unsurfaced gravel and clay that turns greasy fast in rain. Best run July through September when water levels drop and mud dries. No permit required. Fuel up in Nordegg before you leave — there’s nothing out here. Cell service is nonexistent. Dispersed camping is available throughout; the meadows at Grave Flats are worth an overnight fire and a cold morning before you push further north.

Frequently asked questions
Can a stock 4Runner or Tacoma handle Hwy 734 between Blackstone Gap and Grave Flats?
Yes, a stock 4WD with decent clearance (8+ inches) can manage this route in dry summer conditions. Low-range 4WD is useful for the Blackstone River crossings and any soft sections after rain — don't attempt it in a 2WD or crossover.
When is Hwy 734 through this section actually passable?
July through September is the reliable window. Spring snowmelt keeps the Blackstone crossings high and unpredictable well into June, and early fall snow can close the route by late October. Check Alberta Forestry road conditions before you leave Nordegg.
Do I need a permit to drive or camp along this section of the Forestry Trunk Road?
No permit is required to drive Hwy 734. Dispersed camping is allowed on Alberta public land under provincial regulations — no fee, no reservation, just follow the 14-day stay limit and fire restriction rules posted by Alberta Forestry and Parks.
What's the hardest part of this trail and what should I expect?
The Blackstone River crossings are the crux — water depth and current vary significantly by season and recent rainfall, and there's no bridge. Scout on foot before you commit. The rest of the 38 miles is rutted dirt and gravel that's firm when dry but gets greasy and slick fast after any precipitation.
How far is it to the nearest fuel stop, and is there any cell service on the route?
Nordegg is your last fuel stop — top off there, full stop. There is zero cell service for the entire 61 km stretch, so download offline maps and let someone know your itinerary before you roll out.
