Bear River State Park, State park near Evanston, Wyoming, US

Bear River State Park is a 324-acre (131 ha) public recreation area on the east side of Evanston, Wyoming, straddling the Bear River. It has 1.2 miles of paved trail, an arched footbridge over the river, and 1.7 miles of packed gravel trails. A small herd of captive bison and elk lives in fenced enclosures.

Bear River State Park was established in 1991 and is managed by the Wyoming Division of State Parks and Historic Sites. It lies on the east side of Evanston, where it straddles the Bear River, and covers 324 acres (131 ha).

The Bear River Rendezvous is held each year on the weekend before Labor Day in the southern part of the park. Participants re-enact the trapper rendezvous of the mid-19th century, when mountain men gathered to trade and socialize.

The park is open year-round and has no overnight accommodation, so visits are day trips from Evanston, whose downtown is linked to the park by the Bear River Greenway trail. The 1.2 miles of paved path and 1.7 miles of packed gravel trails are groomed for cross-country skiing in winter; snowshoers also use the park in that season.

The park keeps a small captive herd of bison and elk behind fencing, so visitors can watch them without hiking far. The 1.2-mile paved trail and a 1.7-mile packed gravel network meet at an arched footbridge over the Bear River; in winter the same paths are groomed for cross-country skiing.
