This spread is credited with inventing the dude ranch, back in the late 19th century, and it's still going strong as a working cattle ranch. Its location, west of Sheridan on the edge of the Bighorn National Forest, makes it ideal for horseback riding, fishing, cookouts, and pack trips. The ranch can accommodate 125 guests, and reservations for the summer should be made by March. The facilities are a collection of one-, two-, and three-bedroom cabins and the main lodge. There's a one-week minimum stay mid-June through August and a three-day minimum stay the rest of the season.
