The Montour Trail offers a prime example of a superb rail-trail experience right in the vicinity of Pittsburgh. As one of the nation's longest suburban rail-trails, spanning approximately 47 miles along a relatively flat half-loop, from Coraopolis by the Ohio River to Clairton along the Monongahela River, it provides an extensive recreational pathway.

Branch routes extend its length to over 60 miles, with a northwest branch directly linking to Pittsburgh International Airport. Additionally, it seamlessly connects with other regional trails, including the Great Allegheny Passage and the C&O Canal Towpath, forming part of the extensive 300+ mile trail network from Pittsburgh to Washington, DC.

It's easily accessible by car and public transit, with numerous access points and ADA-compliant facilities along the way, ensuring a convenient and inclusive experience for all trail users.

National Tunnel

Highlight • Structure

At 623 feet, this is the longest tunnel on the Montour Trail and has lights on throughout the year to help see your way. During the winter, the two entrances are sealed to prevent the buildup of ice, which could reach 2-3 feet thick due to the high moisture dripping from the walls and ceiling. Trail users can still enter the sealed tunnel via doorways throughout the winter and find a balmy interior. The tunnel was bored in 1913 and lined with concrete in 1928. Operations ended in 1980 and it became part of the Montour Trail in 1992.
