The red line on the map is horrible- just a rough approximation of the route. Download the Road overlay map to help figure out where the trails really go! It's more than 2.5 miles- more like 4 miles. But the trails are well-trampled and varied with upland and streamside terrain, some open field but mostly wooded. Very nice for a county park.Karen Kassekert2 months agohikingWe found nothing redeemable about this trail. It is incredibly muddy throughout, in addition to the multiple times you cross the creek. It is not well marked. Several times, we thought we were going to find a beautiful view or the waterfall. Instead, we found openings to corn fields. We also found a clearing with lots of beer bottles. We heard ATVs throughout our hike. We passed two people on horses. It seems like a good trail for horses.Frank Rizzo5 months agohikingThe local rednecks ride the their ATV's illegally on the trails (and on the public roads) and account for much of the beer can deposits. It's clearly marked at the trail entrance that no motorized vehicles are allowed on the trail. They will typically stage their ATV's at the empty lot next to 2509 Flag Marsh Rd and ride down to the trails using the public road. DNR has made some progress in cleaning up. The equestrian's have reported negative encounters with the ATV's. If you encounter an ATV on the trail, record it and send it the Carroll Country Sheriff.

It was nice and short for them. super muddy and rocky. didn't see a waterfall, but did see an area that people use for a dump, full of burnt beer cans. the trail had no markings thank goodness for the map. I don't think that we will be going back there again.Claudia Olson1 year agoKate, you can use this map I found online: http://www.carrollcountyequestriancouncil.org/TrailMaps/GillisFalls.pdfKate Speelman1 year agohikingCan someone please direct me to where I could find a trail map of this park? It doesn't seem like it's clearly marked anywhere.Samuel Wilson3 years agomountain bikingReal muddy after rain, but fun ride in Mt. Airy.Debbie Patton3 years agohikingAfter August 31st trail is not open on Monday-Wednesday - Fridays.Claudia Olson4 years agohikingI didnn't have a map or any real idea about this trail. So I parked where there was another car and started on A trail. The stream ran along the west side of the trail...and then I came to a point where I needed different shoes or bare feet (not in January) soI turned back. Now I've seen some maps and will try again another day. In the winter this trail is only open to hikers on Tuesdays and Thursdays.Laurie Soller5 years agotrail runningThis is actually a horse trail through the woods and across a stream. Beautifully scenic and tucked away, it is a very rustic trail, more suited for hiking and riding than running, but for the sure-footed adventurous trail runner, it's short and sweet. It's pretty much got it all, from good short hill work, to stream crossing (make sure you wear your old shoes, cause you're gonna go through a stream that's about 6" deep at its center and it's impossible not to immerse your whole shoe) but the water is just right to cool you off! You traverse the stream twice during the run, and follow it throughout, so if you're listening to the sounds of nature, you can hear it babble which adds to the pleasure of the run. In the middle it's nicely flat so you can enjoy the views of the forest. At the end, there's a kicker hill about a quarter mile long and very steep on blacktop. Most of the trail, except the very end, is uneven dirt with stones, rocks, and some natural obstacles (fallen trees, puddles, poo piles). I did the loop twice and found it VERY enjoyable and will definately be on it again!
