Brannan Park contains one of Auburn's most heavily used sports complexes. The City sponsors many sports events at Brannan Park; Cascade Middle School users and a variety of organizations - youth soccer leagues, Little League - also use the playing fields extensively. Brannan Park is on a flat, open site, with the Green River forming the park's eastern boundary. There is a loop trail within the park that will eventually connect to the Green River Trail. The remaining sides are bounded by residential housing, which is highly visible from the park.
