The Quarter Circle A Nature Trail is a primitive 2.4-mile walking trail intended for wildlife viewing, allowing visitors to experience the beauty of the Quarter Circle A property. The trail begins across the Little Goose Creek bridge and continues along the west side of the creek. The trail travels through upland prairie, mountain foothill, and lush riparian habitat.  We encourage you to bring your binoculars. While on the trail, visitors may encounter deer, marmots, other small mammals, reptiles, and amphibians along with a variety of bird species. To both protect and conserve the many wild birds, Bighorn Audubon Society, in cooperation with Audubon Rockies, and The Brinton Museum have formed a partnership to designate 620 acres of the Brinton property as an Important Bird Area or IBA.  

The trail is open during museum hours. The hiking difficulty is Moderate on an underdeveloped, narrow, game trail. Sturdy footwear is recommended. Please note that the Nature Trail is closed to mountain biking, motorized vehicles, and dogs to minimize impacts to sensitive wildlife species and their habitat. Stay on the trail to prevent erosion and the spread of invasive species.
