Idaho Centennial Trail

Confusing Intersections
Expect map errors.
You will approach the basin on Forest Trail 002. When you get to Stonebreaker Ranch, you will bear left on Forest Trail 001, Chamberlain Basin Trail. Follow Trail 001 from Chamberlain Basin downhill to the Campbell's Ferry Bridge on the Salmon River.

Difficult Routefinding
Route-finding can be difficult on the Stateline Trail on the Idaho-Montana border. This is particularly true between Hoodoo Pass and Mullan, and between Mullan and Clark Fork. The single-track trail becomes criss-crossed by roads as you travel north from Hoodoo Pass. A number of logging roads will create confusion on the state boundary as you travel north. The best thing we can recommend is to pre- program GPS waypoints into your GPS unit to stay with the route.

No Trail
Between Fault Lakes and Hunt Lake, there is no trail. ICT users will need to bushwhack between the two lakes. From the smaller Fault Lake you can follow rock ramps up to the saddle overlooking Hunt Lake. From the saddle stay left travel down a steep talus slope to Hunt Lake. Traverse around the south and west side of Hunt Lake. The east side of Hunt Lake is thick brush. Pre-program GPS waypoints in this area to keep yourself on course. From the Hunt Lake outlet, the trail to the trailhead is almost continuous boulder hopping. The trail route is marked with orange spray paint dots on the boulders.

last water before long hot dry descent

Blowdowns
There’s nothing to do but bushwhack around it.

Map error?
The ICT takes the Lolo Motorway (Forest Road 500), then turns off north onto Liz Butte Road (FR 560). But it does not take Liz Butte Road all the way to the top of Liz Butte. It follows that road to the sag at point
and then heads off to the right on FS Trail 649, “Liz Butte Trail”. Trail follows a more-or-less level contour until it reaches the track of the trail shown on the Idaho Parks map.

Trail may not exist
I took an unmapped ATV trail north, then turn right, then come out on Road 4203 just north of the foot of Copper Lake Trail. Turn left and follow this road (the bed of the old Northern Pacific Railroad) west to Willow Creek. Pick up the published ICT route there, and go downhill toward Mullan.
