Review: Great place to go when everything else in the DC area is too wet to ride. Lots of rocks, very little dirt. Technical but no big features. Not very flowy, but fun! Trails are fairly well marked. This is a review of the 7.5 mile yellow loop.

Review: Very tuff course from most of tge starts and especially if starting from top. Only one course is intermediate i would say. The remainder are black diamond at least. Just extremely rocky terrain from the jump off. I loved the challenge but you better bring your A game or you will be tested.

Review: Did 20 miles yesterday in the fog and rain. Very demanding but beautiful. The trails are rocky but you can all downhill and many uphill. Be very careful when wet the rocks and especially the logs are very slick especially near (and in) the streams - falls come hard and fast. Great workout for your entire body!

Similar Trail: Similar to Dolly Sods but much more rideable

Review: Trails are very well marked and not for the faint of heart. The yellow loop was awesome ridden Clockwise but looks to be fun both ways. The black trail is definitely more DH clockwise. Counter cw is mostly very technical climbing. Amazing DH from the overlook at the road on black.

Review: Tried this for the first time and rode the whole yellow trail and some of black. It was fun, but some of it was hard for the sake of hard. Definitely a place to test your (and your bike's) capabilities, but I'd prefer less rocky trails. The trails were covered with leaves which was definitely not ideal, but even with that I had probably half a dozen spots where I had to at least put a foot down if not walk 20 feet. Without the leaves, I think that would have happened only a few times. So if you want to feel challenged, this is a good place, but if you want to go fast with little concern for hurting yourself or your bike, there are better places.

I do think that if you're considering going from a hardtail to a full suspension, ride this first with your hardtail then you will feel really good about the decision of getting a full squish bike.

Review: Took on the challenge of the Green Trail Monday around lunch time on June 8th. Only saw one dog walker and one trail runner. The green trail is a lot of fun going down (roughly a mile), coming back up is a hike (1 mile), literally hiking a long side your bike. Will be taking on more of Gambrills trails soon, will post review then.

Review: Definitely not for the faint-of-heart. I consider myself an intermediate-advanced mountain biker and I would be seriously impressed if someone could ride the black loop without getting off and hiking at any point. I would not rate any of these trails in this park below a moderate in difficulty (and neither does the park). That being said, the yellow loop is a great one to get a little more distance, but all of these trails have some seriously challenging features. All of them have technical climbing and descending involved as well as sharp, jagged rocks protruding from the ground ready to slice and dice those light-weight XC racing tires you're rocking. What's great about these trails is that they're extremely well marked, they offer some great technical challenges, some nice scenic overlooks, and you will get a lot of elevation on your ride if you continuously start onto your next trail from the main parking lot. Note: I tried the black loop in the counterclockwise direction and it seemed as though the clockwise direction would have been the better choice.

Review: This trail is very rocky and for that reason i could only get in 4 miles on the Yellow loop.I did ride some of the black and blue trails.Most of it is more suited for hiking.I can see tougher riders liking it.It did end up with about 6 miles,far less than I wanted.All i can handle of this rocks trail.
