Kuskanax Creek FSR to McDonald Creek Summit — Upper Arrow Lake
Selkirk switchbacks with consequence.
Nakusp sits on the shore of Upper Arrow Lake in the Selkirk Mountains, and most people passing through grab a soak at the hot springs and keep moving. The ones who know better turn up the Kuskanax Creek FSR and start climbing. The road rises aggressively from the valley floor, passing through second-growth cedar and hemlock before breaking into old burns and subalpine terrain near the McDonald Creek drainage. The upper section narrows to single-lane with loose rock surface, erosion cuts, and switchbacks tight enough to require multiple-point turns for longer rigs. The summit ridge delivers 360-degree views of the Selkirks and Monashees that genuinely earn the drive up.
This is expert territory for anything over about 200 inches of wheelbase — a compact or mid-size 4WD is significantly more manageable on the upper switchbacks. Lockers are useful, not mandatory. The road typically opens late June depending on snowpack and closes hard by mid-October. Fuel in Nakusp. No permit needed, limited dispersed camping on the upper benches. Cell is gone past the first couple of kilometres. The descent demands low-range, cool brakes, and patience — don’t rush it. This one separates the drivers who know what they’re doing from the ones who thought it looked easy on a map.

Frequently asked questions
Can a stock Tacoma or 4Runner handle this trail, or does it need to be built?
A stock high-clearance 4WD with low-range can make it, but you'll be working hard — the upper switchbacks have loose rock and off-camber shelf sections that punish anything with limited articulation or street tires. Skid plates and all-terrain tires are not optional here. A lift helps but isn't the deciding factor; driver skill and mechanical condition matter more.
When does the Kuskanax Creek FSR actually open after winter, and can snow linger into summer?
Late June is the realistic opening window, but snow can persist on the upper ridge sections well into July depending on the snowpack year. Don't assume it's clear just because it's July — check with the BC Ministry of Forests Kootenay Lake District or ask locally in Nakusp before you commit.
Do I need a permit to drive this FSR or camp along it?
No permit is required to drive or camp on BC Forest Service Roads — dispersed camping is legal on Crown land along the route. That said, this is active forestry land, so watch for industrial truck traffic and obey any posted road closures, which can happen with little notice due to fire or logging operations.
What's the hardest section and what actually makes it dangerous?
The descent off McDonald Creek Summit is where it gets consequential — steep, loose switchbacks with limited recovery room and significant exposure on the downhill side. One bad line or a brake fade situation on a hot descent can put you off the edge with no guardrails and no one coming to help. This isn't a trail to attempt if your brakes are soft or your rig has any mechanical doubt.
How far is it to fuel and supplies, and is there any cell service if something goes wrong?
Nakusp is your last stop for fuel, food, and water — top off everything before you leave town. There is zero cell service on this trail from start to finish, so a satellite communicator is your only emergency lifeline out here. Don't leave Nakusp without one.
