Getting There

This loop covers the majority of the Avalon area, with multiple ruins, waterfalls and other artifacts to find along the way. You will see some settler homes (two of them) one with a dated gas pump 1930s era as well as two old possible outhouses that are probably state park buildings (old ones). This hike also features the Cascade falls area where you can view some of the best falls in the state! The falls are in a valley area and very secluded. A side hike loop is added for length, and adds some more ruins for some old piping fixtures and a barrel. Going over the swinging bridge you will find the ruins of the "superlative" company along the railroad tracks. More artifacts along the side of the road, as well as railroad bridges, tunnels, and aqueducts.

We enjoyed parking off of a road through the tunnel. There was a line to get in the park but It didn’t feel over full. Lots of people playing in the river. We walked all on road or paved trail and checked out the bridge. It was neat. Lots of shade. We took the dog he liked It. We did 2 hours/6miles. We will be back to do more of the wooded trail areas.

This trail is not too difficult, because you can essentially make it as short or as long as you’d like. Lots of options for turn offs. Lots of mountain bikers like to use these trails, along with hikers.

Trails are not marked well at all. Riding through the field's was cool, but once ya get into the woods, the trail gets narrow with plenty of roots and other obstructions. Great workout, but plan for a long, sweaty day.

The trail was great! Trail was paved and very well kept. The view is pretty, easy to find parking. No trash along the trail. Ended up going Over the swing bridge and hiking the cascade fall trail which was pretty steep and extremely well kept and easy to track the trail throughout the way.

My wife and I took our dog and she loved it. However, the trails weren't really clear and we didn't know where to start or where it looped. After one path be backtracked to another path that was overgrown and hard to follow at points. Ended up going back the way we came and heading home. We decided to not go back because of the conditions of the trails.

It was a nice trail but be warned that there is an entrance fee for the park. It's $3 for locals and $5 for out of state. You can park in the local neighborhoods but the locals don't seem to welcoming to park visitors, but most of those signs are homemade so they're really not legal. The trail does not necessarily follow the dotted line like it shows in the map. When you hit the end you can't come back on the River Road trail unless you want to walk your bike part of the way. Some of the side trails are nice too but unless your are serious mountain biker I would not do them all bike. They seem more like hiking trails. All in all it's a nice park and beautiful scenery.

the hike was beautiful and the Park Rangers or Volunteers were very helpful in getting me to the portion of trail I wanted to be at. I didn't see any rumored "ruins" but the trail has lots of waterfalls, a cool swinging bridge and lots of BIKES. The people on bikes were very friendly but they rode fast and you have very little time to move out of the way. I'd go again though.

Apparently "At capacity", wasn't able to hike it. They also had signage saying there are current projects happening in the area effecting access.

Please remove the protruding blowdown at 39.23987, -76.74987 — it is a true hazard and someone could get hurt. Otherwise, 5 stars. Completed: 07/19/2018

Ran a segment of the Avalon Loop Trail. Great trail for running, but watch out for bikers! This segment is one of my go-to courses for training and mile repeats. 4 miles total. Completed: 07/15/2018

Opened up again (at least the Morning Choice portion off of Landing Rd). I was here yesterday and despite being a bit muddy, it was a great hike. One of my favorites in close proximity to Baltimore.

Due to the weather we have had as of late, this section of the park is closed. The Avalon Loop doesn’t exist
