Garrett Park is primarily a residential town, with a post office, and a few small businesses. The only road open to automotive traffic into or out of Garrett Park is Maryland State Highway 547 (Strathmore Avenue). The town is served by the MARC Train Brunswick Line. The town is unusual in that residents pick up their mail at the post office in person, rather than having home delivery.
