Idaho Centennial Trail official route

The 900-mile (1,448 km) Idaho Centennial Trail (ICT) is a scenic trail through Idaho. It winds its way through various ecosystems from high desert canyonlands in southern Idaho to wet mountain forests in Northern Idaho. ICT travelers will cross many mountains, streams and rivers in between.

The Idaho Centennial Trail (ICT) route is along existing trails and primitive roads. Hikers typically start at the southern trailhead[2] near Murphy Hot Springs on the Idaho-Nevada border in early June when snow levels are starting to recede and travel northward through high desert with the goal of entering higher country before the heat of summer sets in. As thru-hikers approach the Sawtooth Mountains the snows have receded enough by mid-July to allow for easier and safer travel. The end of the trail at the Idaho-British Columbia border must then be reached before the snows of late September/early October.

This hike should not be attempted by anyone. This is not a backpacking trail that can be compared to other National Scenic Routes. You will not experience well-groomed trails or signs, in many places, no trail exists. The Idaho Centennial Trail is a wilderness experience, not a backpacking trip.
