Feel the thunder and witness one of the last great events of the old west. Watch as cowboys, cowgirls and park staff saddle up and roundup Custer State Park`s 1,400 head of buffalo. After the roundup, park staff sort, brand and vaccinate the animals for the November sale. One of the nation`s largest buffalo roundups. Breakfast is available in both veiwing areas and lunch in the corrals following the roundup.
