Huge park. Trails everywhere. Fun for the dogs.

First time on this trail, not bad. Water was too high on the most direct stream crossing in the beginning and was definitely not a good idea to go this way on the day I went. Signs direct you to go this way, so just make a good judgement call. I had to go a bit further to get a lower area and that took up some time. It also got a little confusing after the underpass, as there are many unmarked side trails and the trail merges to the white aren’t well marked. Made it to the second telephone line field before I had to turn back. Would like to go back and finish the rest!

Well maintained, scenic trail. Bike, dog, and kid friendly. Would recommend for friends, family, or solo hikes. Plenty of space and trails for everyone.

I went with a friend and brought my dog along. although it is currently winter and the forest floor is covered in leaves. It was still a very enjoyable hike my dog had a grand old time admiring the many baby deer we came across. We only got through half the trail but we will definitely be back!

Started by the rapids— lots of people, thinned out by about a mile in and then almost no one. I only did a portion (5 out, 5 back) but it was beautiful and not challenging. Most of the trail is along the River (which is gorgeous) and the trail is well maintained. If you want to go off the trail the underbrush is easy as well, sometimes I went off the main trail to be closer to the water because it was so nice. There’s a $3 honor system at the parking area— bring some cash so they can get some help continuing to make this park great!!

If this is moderate I’d hate to see hard!! Excellent trail

Started out on the rapids trail and had to cut across the river by walking on a fallen tree about a mile or two down the trail. It’s a small cut out on your right that you should take. Once on the other side, the trail is well marked with white and then turns in to neon yellow and white blazes. I walked the entire trail and went to see the church ruins. Was about a 19 mile round trip. Took about 6 hours. Very long day, but a wonderful experience.

Awesome trails many nice views. This was my first hiking experience. We started off on the blue trail (cant remember the names of the trail) then we went onto the white trail from there it switched to the orange trail, once again the white trail and then onto the red trail on our way back to the car. Really nice loop I decided to go by Yi-Shin’s recording. Some parts were muddy but through this way we saw the trail clearly no overgrowth or anything. We got to see a chipmunk and a snake.

Very pretty along the river. Fun crossing it. Be careful with the trails. We missed a turn and ended up bushwhacking. The trail is very overgrown for much of the length, at times almost completely disappearing under ground cover.

Interesting to see the scattered ruins and explore the little trails and loops. I didn’t see any signs saying no dogs - I brought mine - but do not recommend for dogs. There is a lot of broken glass in a lot of places.

Patapsco Valley State Park - McKeldin Area Note to self, check what time the park opens before you show up at 6am and the park doesn’t open until 9am. No real good way to get to the head of the trail, no parking outside the park. No matter, decided to go to the other end since it was an out and back. No luck there. After planning this 16 mile hike I aborted and hiked the opposite side of the Patapsco. Inside Patapsco Valley State Park but outside the McKeldin Area. There is a small gravel lot at the end of Johnnycake Rd. Great hiking with an ample amount of elevation change. Lots of great things to see - waterfalls, steam crossings, walked along the train tracks and the river. There is a trail that avoids the train tracks, I’d recommend this option, the gravel along the tracks is baseball sized and loose, hard walking. There are a ton of footpaths that bisect the main trails although some are not often traveled and you have to use you imagination or in my case my alltrails inspired imagination, All in all pretty nice trail, some trails washed out.

Pretty easy to find the Arch. Just follow the stairs. We brought our 5 month old pup. He loved it just need to be careful of the broken glass. We had our pup wear boots for this hike. Besides that it was pretty cool! Worth seeing!

The place is great, and if you wish to see some abandoned building with different graffiti,then this is the right place to go. Compare to other trails with clear direction, some ruins in this trail may be difficult to find, so just walk around, and you will see some interesting stuff

Nice for more seasoned hikers. Trail is hilly and rocky but doable for hikers and dogs. We saw evidence of horses as well. Pretty views of the river.

If you love to see abandoned buildings and wonder about their past, and you like to view graffiti, then this is the trail for you! It has a lot of different pathways that jut out from it, but they all bring you around to where you need to be to see the glory that is left of Saint Mary's college. I can't wait to go back when the leaves are in. It's not a difficult trail, but initally it's a huge set of stairs that are daunting, and kind of a climb. There are lots if stairs built into the hills of the woods, and some of the trail is on what used to be a road of sorts. Definitely a lot of fun. Many people were out when we were hiking, but it was still a very quiet trail, nd a good place to reflect. While we passed a lot of hikers and their doggos, we still felt very much alone with nature.

it was pretty easy to find

I had a great time here in a class for compass with REI so much fun

Hard to find and lots of stairs! Loved seeing the chapel. You can bring your dog, but there's a lot of broken glass all over.

Okay just did this very short hike. First thing, you can’t take river road from thistle to get there. Take hilltop all the way to river road. Trail is clearly marked and heavily used. I was there around noon on a Sunday with about 10 others on the trail. The college is on a mountain top accessed by a lot of steep stairs, watch your footing. Not much remains except the skeletal dome of the alter some basements and foundations all located on the hill scattered about. High creep factor. The views of the valley, river and trestle bridge are great but I’m certain only in fall and winter. Any other time it would just be too over grown.

I ran this trail in preparation for a 1/2 marathon trail run. With close to 1,000 feet elevation gain, it is good practice for uphill (glutes) and downhill (quads) technique. Mostly shaded, it is a comfortable run. There are some sections that are fairly rocky so be prepared for your ankles to be a bit sore. You will have to park at the bottom of Quaker Hill and have someone pick you up at the Woodstock Inn.

A fun one. Definitely a little spooky but that’s what made it cool. Enjoyed how there were a bunch of different little trails you could jut off on to.

Amazing views . Parts are challenging especially to beginners . But awesome landscapes

I really liked this one!! The most challenging part is finding it. The alter is downright creepy and even though the structures were torn down they left the basements. We crawled through the holes in the ground and entered this dark empty rooms. I rated it high not for the hike, not that challenging, but for the eeriness. I believe this is private property so it may not be accessible anymore.
