Tiwinot is an intermediate rated single track trail that winds between the Teton Way and Glacier Way trailheads.  Short technical sections of rock make this trail both flowy and challenging for trail-goers of all types.  Tiwinot meanders through stands of logged old growth forest and open fields of mules ear flowers.  Near the top, views of Donner summit can be seen.  Use this trail to connect a loop outing with the Donner Lake Rim Trail.
