Trail Description
About this trail
It starts out as a gravel path. About 1 mile in the trail curves to the left, but straight ahead there is a single track path. Go across the creek and follow the path. You will end up at the Cottages at Algonkian park. Follow the road about 1/4 mile and you will see a picnic pavilion on the right. Go down the service road entrance on the right (yellow gate) and follow the trail down by the river. When you hit the boat landing, go across it and it keeps going along the river. It goes another 3/4 mile before it ends.

Review: I do live near the trail and all the ENTIRE gravel trail and all it's connecting trails IS private property (signs all around as well as a camera hidden in the trees). It is NOT public land. It does end at the Algonkian Regional Park property line ot the east and a farmer's private property to the west. Loudoun County Sheriff's office DO patrol there daily. I've witnessed them asking for proof of residence in Countryside, dog licenses...etc. So, those of you who are complaining about it being private and NOVA is all uptight...contribute money towards the maintenance of this trail (WE as homeowners in the community pay...not any local government or organization)....and you can use our trail!

Review: Perfect for an experienced rider's weekday workout as well as a beginner's adventure. Paths along the river as well as some creeks. Narrow single tracks cut along tall woods. Nice quick fun on the weekends.

Review: I haven't seen any cameras...I have seen signs thats about it. Why would an HOA waste money trying to police this trail...I ride in ride out...not an illegal dumping trash and coronal bottles in the woods.

Review: Great Trails for Countryside Residents, but it is private property and they now have cameras and a communtity policing officer enforcing the no tresspassing policy. Algonkian Regional Park is not much better since the White Trail does not allow bikes.

Review: All, the gravel trail as shown in the GPS map is on private property. It belongs to the CountrySide homeowners association and is not open to the public. A sign on the trail entrance says as much. Algonkian Park abuts the CountrySide HOA property to the east (downstream from the Potomac). Algonkian Park limits biking to pavement and the sewer line road. Bottom line- there is no publicly accessible 'sweet single track' in Horsepen Run or Algonkian Park.

Review: I went to the trail head as described and seen on google map. This is a private lot and the park said private property. It seems to be permit only at that parking lot, as part of a community association. I believe that there may be public access at 47001 Fairway Dr. Sterling, VA 20165 {Algonkian Regional Park}. I will verify this, provide directions, and review the trail a.s.a.p. If you go into Algonkian Park, turn left at entrance, turn left at end of that road and park around boat ramp, then you are starting from a public area. The trail is more of a short hiking trail along the river. There are a lot of families and fishing. It is a scenic area. It would be more fun to walk around since it is not trimmed back very well. I do not know about the gravel trail from the private lot.

Review: It's all gravel. Nothing special at all. It does, however, have many hidden trails on the side that can be fun. Length is roughly 1.3 miles. I like it for the side trails, but those trails are extremely short (

Review: This trail IS PUBLIC!!! I live next to the trail and ride it frequently. Overall the trail is about 5 miles if you follow it all the way. To start you need to go on Sugarland Run and go Under the Algonkian park road you have to cross the river twice then take a right and follow the trail.

Review: How is it's accessed from a public park. I rode it today and saw no signs about trespassing. People here in NOVA need to stop being so damn uptight....
