Brewster Lake actually is in the Gros Ventre Range, not the Wind Rivers. Says TomT
Brewster Lake is a beautiful lake in the Wind River Range. This lake is so wonderful. Triangle Peak is a peak you can catch a sight of from Brewster Lake, and take a visit to nearby Timberline Lodge and ride a horse. Dry warm beds await you at Headwaters Lodge And Cabins. If you came to camp Granite Creek Campground is a wonderful place to do that; one of the
overriding marks of the surroundings of Brewster Lake is Doubletop Peak. Not enough hours in a day to enjoy the Wind River Range. Camping at Crystal Creek Campground is always a great experience; a pleasant tour to Grizzly Basin is a good way to spend an afternoon.
