How is the Idaho Centennial Trail signed?

The Idaho Centennial Trail has been signed with the ICT logo (shown at left) from the Idaho-Nevada border to the southern boundary of the Frank Church-River of No Return Wilderness, near Stanley.

Signs have been placed at all key intersections in both directions. Signs are either placed on free-standing posts or they are affixed to trees. The goal is to place ICT signs along the entire reach of the ICT, except in areas where the ICT passes through federally designated wilderness areas. In wilderness areas, ICT users will need to follow signs for the particular trails they are traveling on.

Even in areas that do not have ICT signs per se, the Forest Service often has trails signs posted for various trails that the ICT route follows.

Leo Hennessy, Non-Motorized Trails Coordinator for the Idaho Department of Parks and Recreation, has led many trail-signing volunteer projects over the years. He plans to work on signing the trail north of the Lochsa River and in the Idaho Panhandle in the near future.
