Getting There

Patapsco Valley State Park charges a fee to enter. The fee is $5 per vehicle. In addition to the hiking trails, there are plenty of opportunities for kayaking in the area.

Parking: there are only 6 spots in the lot. There are tons of no parking signs all along Daniels Rd, so don't park on the side of the road. They will ticket you. If the parking lot is full, you can reportedly hike about 2 miles to here from the entrances at Carrie Way or Old Frederick Rd (by railroad tracks). There are also other areas of Patapsco with water access and more parking.

Great hike. Trail hard to follow down by the tunnel but otherwise easy. A little muddy but nothing some good hiking boots can’t handle.

Went on a Thursday around 11am. Be aware, very limited parking. If first lot is full there’s another one further down. On a weekend can easily fill up quickly. Trail is not well marked, so stay along the river. When you reach the end, you’ll find train tracks with a tunnel. To complete the trail just come back the same way so you don’t get lost. Very easy hike, picturesque along the river.

Well kept trail, if a little muddy, some great spots to stop. Saw some beaver sign, pretty cool to see less than 5 miles from the inner harbor.

Icy

A flat trail that has some icy/wet spots due to the lack of sun hitting the trail. I took the trail to the end to the Railroad tunnel. This trail easy on the legs. Now the big issue. Even in December pretty busy. With limited parking spots. It’s ridiculous that the county put up hundreds of no parking signs along the road. Also the Church on the hill is pretty Unique since it’s built in the 1800s. Odd place to put a Church in 1873.

Since there is only the one marked trail we did our best to follow the map but missed it and cut the hike short. It’s beautiful there and we so a ton of birds. Beautiful woodpeckers and bluebirds. Colors were amazing. Definitely icy. I wish they would Mark more trails.

Very pretty in the snow. Tough river crossing to get onto the trail—make sure you have waterproof boots. A bit icy in parts. Well marked, and probably really nice in summer too.

Pretty great trail to take and was able to get a lot of photos. Trails are easy to follow and great views. Be careful of the mud after a rain though

A little busy but definitely worth it. It’s easy to get lost and we had to cut off one side of the loop at the top because we could t find it. Parking was scarce but the trail itself was a great for a spontaneous bike trip. 90% of it is flat

HikingGreat!Muddy

Great trail - very easy to follow and quite flat, with a nice view of the water the whole time. It was a little damp (about 36 hours after rain) but there were enough side paths that you could avoid the mud. Regarding parking, it was definitely a problem. I went the day after Thanksgiving and assumed that no one would be out giving tickets, so I parked by the side of the road near the church on the hilltop.

HikingMuddy

Nice trails - I got lucky with the parking and only saw 2 other people out there. A cold dreary day seems to be the time to go! The trail along the river is pleasant and easy enough, although expect it to be muddy after a rain. The trails in the woods aren't very well marked, and even with the app I still got off track a couple times. Lol so about that parking...a lot of reviews for trails at this trail head mention parking can be an issue, and yes there are only 6 spots in the little lot. There must be 100 no parking signs all along Daniels Rd, so don't park on the side of the road. Yes they will ticket you, but mostly it's just kind of disrespectful to the area residents and DNR's efforts to maintain this area, it's not meant to entertain hoards of people at a time. If the parking lot is full, you can still hike about 2 miles to here from the entrances at Carrie Way or Old Frederick Rd (by railroad tracks). There are also other areas of Patapsco with water access and more parking.

WalkingGreat!Muddy

Definitely do this hike in the fall! It is soooo pretty with all the different colors! However, you might want to go early. There is 2 tiny parking lots at this trail head that fit a total of 10 cars.... so if you don’t get a spot, you’re SOL. The last part of the hike is steep into the woods, but the trail was buried under the down leaves so we did get a tad bit lost, but it was still fun. Also, the old church building covered in graffiti is ACROSS THE RIVER. It is not located on this trail. We waded through the river tho and got very soaked.

Nice trail! There weren’t a lot of people on this mid-morning/afternoon Sunday! Saw some ducks, horses, and deer! Overall will do again.
