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,[3] as well as smaller waterfalls on the Youghiogheny River and Tolivar Creek.

"[6] The park had its beginnings in 1906 with the donation by John and Robert Garrett of Baltimore of 1,917 acres (776 ha) to be used as a state forest.

[7][8] Notable persons who have visited the area include Thomas Edison, Henry Ford, John Burroughs, and Harvey Firestone, who camped at Muddy Creek Falls in the summers of 1918 and 1921.

[9][10] The park contains 65 campsites, a picnic area with a pavilion and playground, as well as a mile-long hiking trail through the old growth forest.
