E.B. Rains Jr. Memorial Park, one of the city's premier green spaces, features sports fields, a fishing lake, and picnic areas. The N Line commuter rail station at Northglenn/112th provides direct service to downtown Denver's Union Station, significantly improving transit options for residents who previously relied on highways and buses.
