Located north of the City of Baltimore, Cromwell Valley Park is a stream valley park comprised of 460 acres of pasture, cultivated gardens, open fields, woods, hedgerows, orchards, and wooded piedmont hills. The park, which was formed through the purchase of four separate farms, is owned by Baltimore County but is co-managed with the non-profit Cromwell Valley Park Council ( The diversity of the park’s habitat makes it an excellent area for wildlife. The Willow Grove Nature Education Center, a remodeled historic farm house, is the focal point of the park.

Situated in an area once known as “Lime Kiln Bottom,” the park was acquired by the Baltimore County Department of Recreation and Parks starting in 1993. The park has over five miles of marked trails which take visitors through varied habitats and past historic structures, including lime kilns, a log cabin,and slave cemeteries. A native plant garden, live animal exhibits,and honey bee hives are the focal point for a variety of programs related to conservation, native plants, gardening, wildlife, pollinators, butterflies, and birds. The Baltimore Bird Club hosts frequent bird walks at Cromwell Valley.


To date, over 205 bird species have been reported  on eBird from Cromwell Valley Park. With Loch Raven Reservoir and Gunpowder Falls immediately to the east and with several streams running through the park, water-related species, such as Great Blue Heron, Osprey, Belted Kingfisher, and various gulls and terns, often make an appearance. Swallows are common in the warm months. Song birds include both orioles, Bobolink, Eastern Meadowlark, Indigo Bunting, and Eastern Bluebird, as well as flycatchers, vireos and warblers. Cromwell Valley Park is situated on a fall raptor migration route and its hillside provides a ringside seat for this event. The Hawk Watch in the park has tallied 15 raptor species, including American Kestrel, Merlin, Peregrine Falcon, Sharp-shinned and Cooper’s Hawks, Red-tailed, Red-Shouldered and Broad-winged Hawks, and Bald and Golden Eagles.


Ample parking available.
