Biked the northern end from PA state line into Maryland a few miles. The trail condition is all dirt, with ruts and bumps and is just in absolute deplorable condition. Buy some gravel Maryland and smooth the trail surface out. The trail has quite a grade and is all downhill from PA into Maryland and could be quite nice if the surface were improved.

A great trail and a best kept secret (well, not anymore)! This trail also gets 5 stars because it’s minutes from me and the scenery is great. The inclines definitely make for good exercise! South PG gets a bad rap but they’re so many great scenic walks here!

Nice trail outside UMD. Great view of historic airport.

I ride this trail regularly. First of all you must have a hybrid, gravel or mountain bike to traverse several sections of gravel. My favorite section is between West Springfield and Route 50 because you pass by beautiful Lake Accotink.

If you are riding a bike the hills are tremendous for beginners or if you are looking for a casual ride. Trails are crowded so don’t go fast. Most people are maskless even in large groups. Go early. I have only done bottom half but will go back and include the Brewery as a stop!

Beautiful trail amongst the woods and along the stream.

Taking a “leisurely stroll” on a sunny morning may have it’s challenges, considering the often groups of 5, 10, 15 — or more — cyclists pedaling past you at 10 or 15 MPH. And that the cyclists lack bells or horns doesn’t help matters much. C’mon, cyclists... give “Ma and Pa Kettle” a break, will ‘ya?

Great 29 mile out and back from Route 372 trailhead. Introduced a friend to the trail. Sorely need a big sign for the trailhead and an actual address. Still, it was a great day to be out, nice and sunny. Nice frozen trail on the way out and a little softer on the return. There were a few rock climbers along the river. I thought both bridges were being repaired but the first one didn’t appear to started yet. The trail has so much potential. I can’t wait for the bridges to be repaired. Highly recommend the trail even if it’s a little bumpy high now.

A fine trail along the old Trolley bed. Better to park in Ellicott City end and walk up to Catonsville. Then it’s all downhill for the walk back. Plus a bakery half way up/down! https://en.m.wikipedia.org/wiki/Trolley_Line_Number_9_Trail
