Section 6 of the Lewis & Clark Bicycle Trail can be broken into two segments based on the corps multidirectional travels. Missoula, Montana, to Clarkston, Washington, is a continuation of Lewis and Clark's 1804 travels westbound. The Blackfoot Option from Missoula, Montana, to Great Falls, Montana, follows the route Captain Lewis used eastbound in 1806. Both segments are described below.
Main Route
The main route follows the course of the Lochsa and Clearwater rivers and is fairly level after crossing Lolo Pass. Once you arrive in Kamiah, the route leaves the river valleys and crosses the  wide open prairie to Clarkston.
Blackfoot Option
This option traces Captain Lewis's 1806 eastbound journey. It is mostly on two-lane highways that follow the Blackfoot and Sun Rivers all the way to Great Falls. The Alice Creek Spur is 12 miles in length and you can ride/hike to the top of Lewis & Clark Pass. The Sierra Club has sponsored this section of the Lewis & Clark Bicycle Trail and major funding has been provided by REI.
