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 ago12 Completed10 ReviewsKate, you can use this map I found online: http://www.carrollcountyequestriancouncil.org/TrailMaps/GillisFalls.pdfKate Speelman1 year ago2 Completed2 ReviewsCan 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 Wilson2 years ago3 Completed1 ReviewsReal muddy after rain, but fun ride in Mt. Airy.Debbie Patton3 years ago2 Completed1 ReviewsAfter August 31st trail is not open on Monday-Wednesday - Fridays.Claudia Olson3 years ago12 Completed10 ReviewsI 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 Soller4 years ago1 Completed2 ReviewsThis 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!
