Trail Highlights:
- From the Dry Fork side, the trail climbs steeply through alpine rocky tundra from Brewster Lake. It winds up though rocky outcrops and scrub brush and small trees until reaching an upper saddle with beautiful views of Grizzly Basin, as well as views of the Winds to the south.
- From the saddle, the trial descends through a rocky area and down into the drainage. There are nice views of Sportsmans Ridge, and the back side of Darwin Peak. There is some water down here but not much, depending on the time of year there’s a small pond as well, though this area can be quite buggy.
- Past the pond, the trail continues to drop through pine forest with spots of nice views down to Chateau Lakes. The trail eventually bottoms out at the lakes and brings you to junction with the Gros Ventre River Trail. There is also usually a large hunting camp in this area. There are trails on either side of the river. The best is on the far side which will parallel the creek and take you down to Upper Falls.
Options:
- This trail serves as a great connection for those wishing to do a loop with the Dry Fork Trail and the Gros Ventre River Trail. There are no other connections off of it. You can either go up the Gros Ventre River Trail and connect over to Brewster Lake and out, or vice versa.
