Lewis River Channel Loop is a 11 mile lightly trafficked loop trail located near Yellowstone National Park, Wyoming that features a lake and is rated as moderate. The trail offers a number of activity options and is best used from June until September.
Directions from Grant Village Intersection: Travel approximately 5 miles south, just north of Lewis Lake on west side of the road.
I would recommend going out the Dogshead Trail and returning via the Lewis Channel Trail. Dogshead is pretty boring- just forest hiking. Lewis Channel has pretty views of the river and the 2 lakes.
I have canoed this channel several times. It's best to canoe after the water has dropped its level a bit. June can be hard paddling up stream. Mid July has been delightful. We prefer to canoe this channel because the float down stream after reaching Shoshone Lake is great fun. Be carful to cross upper Lewis Lake, with a canoe, early in the morning to avoid wind and big waves.
