The Big Horn Mountain Roundup (known locally as "the Trailride" is an annual event in the mountains west of Buffalo and Sheridan, Wyoming.  Attendance is by invitation from members of the Board of Directors, and guests come from the local area, both coasts of the U.S. , many places in between, and occasionally, overseas. Usually 90-120 riders participate. A nucleus of 40-50 men attend regularly, but composition of the Ride varies from year to year.

Events begin on Wednesday evening, of the last full weekend in July.  The campsite is selected to be central to the three days' rides.  Rides are usually 12-15 miles per day, through the scenic Big Horns.  Camping is in personal tents. All horses are picketed at night on a high line. All meals and an open bar are provided.  Outhouse and shower facilities are available.

Basic horsemanship skills are a pre-requisite for the mountain trails. Most riders bring their own mounts, but horse and mule rentals are available from a local outfitter, with prior reservation.  Veterinarians, wranglers, and a farrier are available for assistance, as necessary.

Evening entertainment includes live music from local musicians, before and after dinner in the  Bar Tent, and usually an Amateur Standup Comedy event on Saturday.

The Ride concludes with breakfast, Sunday morning.
