USFS Caribou-Targhee rangers now to groom some of the more popular forest trails in Teton Valley, including South Leigh Canyon.
South Leigh Canyon is a favorite summer hiking trailhead. In the winter, USFS grooms the trail, supplemented by snowmobile track packing, along the summer road, as far as the usual summer trailhead- approx 5.4 miles out and back. At 2.7 miles (summer trailhead parking) the USFS grooming ends, however, one can continue to ski further into the Canyon on the snowmobile packed trail, located to the left of the USFS Info Kiosk.
The trail is nearly flat, very tranquil, through forests of conifers, crossing creeks.
The trail is a multi-use trail, open to snowmobiles, fat bikes, skiers, walkers, dogs. We saw only a couple of snowmobiles on our latest excursion, mainly back-country skiers using snowmobiles to access the steeper slopes up canyon. We believe that the trail is only groomed once a week, so you may need to ski on snowmobile tracks, which can be quite good if snow is fresh -not melted then refrozen.
