Swallow Falls State Park is a public recreation area located on the west bank of the Youghiogheny River nine miles (14 km) northwest of Oakland in Garrett County, Maryland, in the United States. The state park features Maryland's highest free-falling waterfall, the 53-foot (16 m) Muddy Creek Falls, as well as smaller waterfalls on the Youghiogheny River and Tolivar Creek. The park is notable for its stand of old hemlock trees, some more than 300 years old, "the last stand of its kind in Maryland."
