Smith Falls State Park sits on the Niobrara River about 12 miles east-northeast of Valentine and holds Nebraska's highest waterfall, a 63-foot spring-fed drop. You reach it by crossing a restored 160-foot iron truss footbridge over the river and following a short trail into a cool canyon. Paper birch and aspen left from the last Ice Age grow there. The park also has tent camping, picnicking, hiking, fishing and canoeing.
