Road: any vehicle
The road to Cooper Lake is about an hour’s drive from Cranbrook on active logging roads. Take Highway 3/95 south of Cranbrook for 12 km (9 km north of Moyie Lake).
0 km: Turn west (right turn from Cranbrook) off the highway, N75148-E81785, onto the signed Lumberton FS road. Stay to the main gravel road, as many new logging roads branch from the main Moyie/Lumberton FS road.
5.3 km: Obscured hairpin curve. Watch for oncoming vehicles on this narrow curve.
6.8 km and 8.2 km: Parking for Moyie Falls (after 7 km sign). Park along Lumberton Road: left side, wide pullouts, two road accesses, not signed. The pullouts are along a winding set of several short switchbacks. The side trip to Moyie Falls is a short hike of about 1 hour return. Hike south downhill from Lumberton Road on either of two old mining roads to the river. It is hard to see the tumbling water unless you cross the unbridged Moyie River. Sometimes in summer you can step on rocks to cross. Head upstream about 400 m. Return to the vehicle and continue the drive to Cooper Lake
9 km: Take the left fork onto the Moyie River FS road (9 km sign). (Don’t take the right fork, Lumberton Road; continue straight ahead.) From here the numbered markers restart from 0; stay on the main road, between the 5 and 8 km signs. There are many logging roads here.
18.5 km: Right fork, signed Moyie Main Road (just before 10 km sign).
20 km: Turn left across bridge on Moyie Main Road (12 km sign). (Avoid the North Moyie right fork.)
22.4 km: Stay on main road, right fork (before 14 km sign). Don’t take Powerline Road left.
25 km: You may see an old trailhead sign here tossed in the bush. The trail has been rerouted to avoid a tricky creek crossing, 1490 m (4,900 ft.). Continue about 100 m past the old trailhead.
25.1 km: Turn left onto the new Cooper Lake FS road (yellow sign), N66008-E64613. Drive south, crossing a new bridge at 800 m. Park before you cross the second bridge, about 200 m. The trail is uphill on the southwest side (right), through a cutblock, N65164-E64359, at 1480 m (4,860 ft.)
