Cromwell Valley Park is a public park just to the north of Baltimore City. The park initially opened in 1993, on 426 acres of rural farm land. It is primarily open fields, woods, cultivated gardens and orchards. The varied terrain provides an excellent habitat for local wildlife, particularly birds of prey which feed on large populations of mice, rabbits and other small mammals. Healthy populations of white-tailed deer, red fox and local songbirds can also be found throughout the park.
