Allstones Lake Road — Bighorn Backcountry to Allstones Creek Basin
Mud, creek fords, and an alpine lake nobody's heard of.
Allstones Lake sits at the headwaters of Allstones Creek inside the Bighorn Backcountry — one of Alberta’s largest and least-visited wildland areas between Nordegg and the Forestry Trunk Road. The access road branches west off of Hwy 734 and deteriorates fast, crossing Allstones Creek twice on unimproved gravel fords before climbing through a dense spruce and fir drainage that sees almost no maintenance. The track is rutted, wet in spots even in August, and narrows to single-lane for much of the upper section. The payoff is a small alpine lake basin with stunning views of the Bighorn Range’s rolling upper ridges and zero other overlanders.
This is genuinely remote — plan for self-recovery, full fuel, and a satellite communicator. A locked 4WD with high clearance is the minimum; a lifted rig with lockers is the smarter call given the mud potential and creek crossings. The Bighorn Backcountry has no cell service and limited signage — a printed topo or offline map is non-negotiable. No permits required. Dispersed camping is allowed throughout the backcountry area; check current fire restrictions before building any fire. Best season is mid-July through September before the snow returns to the upper basin. Fuel up in Nordegg — it’s the last stop before a long stretch of nothing.

Frequently asked questions
Can a stock Tacoma or 4Runner handle Allstones Lake Road, or do I need lockers?
A stock high-clearance 4x4 can attempt it in dry conditions, but the mud sections and creek fords make lockers a serious advantage, not a luxury. If your rig isn't locked, go with someone who is — recovery on this trail is a long way from help.
When does the trail actually open and is snow a real concern?
Mid-July is the realistic open window — snow lingers at elevation and the access road stays a muddy mess well into summer. September is your cutoff; early fall snowfall can close it fast and without warning in the Bighorn.
Do I need a permit to drive or camp in the Bighorn Backcountry?
No permit is required to access the Bighorn Backcountry, but you must self-register at the area boundary before entering — it's mandatory under Alberta regulations. Dispersed camping is allowed; follow Leave No Trace and stay out of riparian zones near Allstones Creek.
What's the hardest section on the trail and what makes it technical?
The creek crossings into the upper basin are the crux — water depth varies significantly by season and recent rain, and the banks are soft enough to swallow a bumper if you pick the wrong line. The mud through the lower sections can be wheel-well deep after any precipitation, with no bypasses.
There's no cell service out there — how far is the nearest gas from the trailhead?
Nordegg is your last stop for fuel, sitting roughly 40–50 km from the trailhead area — fill up there, no exceptions. There is zero cell service on the trail, so download offline maps and file a trip plan with someone before you head in.
