Trolley Line #9 Trail, Catonsville, MD

Back in the 1890s, the #9 Trolley Line connected Ellicott City to Catonsville in the west of Maryland’s Baltimore County. The streetcar line served the local community until the 1950s, and it wasn’t until much later in 1991 that attention turned to transforming the line into something the community could use once again. And so the #9 Trolley Line became a popular hiking and biking trail, and it’s now a favorite dog walking spot for pet parents.

You can walk the 1.25-mile Trolley Line #9 Trail in either direction. But if you want to be going gradually downhill on your return journey, it’s best to start at the Oella Avenue end in Ellicott City. Leashed dogs are welcome on this scenic route, so grab your pup (and their lead) and get ready for a relaxing stroll. 

You’ll need to allow about half an hour to walk from one end to the other, or maybe a little longer if your pup is the type of dog who loves to stop and sniff every smell along the way. As always, remember to clean up after your dog whenever necessary.

The trail is particularly well known for its boardwalk section, which winds its way through 100-foot-high rock walls. The granite here was cut by hand in the 1890s to allow for the streetcar line, and it’s an impressive backdrop for you and your pup to admire as you walk.

Before too long, the boardwalk is replaced by a paved surface as the trail continues to climb up an easy incline. A pretty stream runs alongside the trail, its waterfalls and gentle flow adding to the natural beauty of your woodland surroundings.

Once you and your dog reach the end of the trail, you could turn around and retrace your steps, or maybe detour to check out a cafe or bakery along the way. 

Alternatively, you could check out the Benjamin Banneker Historic Park and Museum, which is located at roughly the 1-mile mark. While dogs aren’t allowed in the museum, your pup can join you while you explore the 6-mile trail network that winds its way through this 142-acre park.

Whichever option you choose, the Trolley Line #9 Trail offers a relaxing and scenic hike for pups and pet parents to enjoy together. Load up your pup and get ready to explore the history and natural beauty on offer.

If your schedule conflicts with your pup's drive for adventure, book a local dog walker with Wag! to keep them moving and exploring!
