Antelope Island is a great place for bison watching throughout the year. However, the best time to spot them is in the summer when the calves are born and wandering around. One exciting chance to watch the bisons is during the Roundup in late October to see them gathered up. It's important that visitors are aware that the bison are not native to the area, but were brought to Antelope Island in 1893, and have survived in the area since then. Show more
