Fountainhead Regional Park is a multi-use area on the north shore of the Occoquan Reservoir between Bull Run Marina and Sandy Run Regional Park. The Park is managed by the Northern Regional Park Authority (NVRPA).


Trail Description: The mountain bike trail is a single use series of loops that feature multiple short, steep climbs and several fast descents. Originally 4.5 miles long, an additional 1 mile loop was opened in the spring of 2000. Thanks to a partnership between NVRPA and MORE the trail has been expanded to nearly 15 miles over the past few years. It features a green beginner loop of about 3 miles, an intermediate loop and an advanced loop. The advanced loop starts with an entrance that earns you the rock star award if you make it due to the steep incline, artfully placed rock step ups and a wooden hairpin turn. Other features include 3 drops, multiple rock gardens going up and down hill and super sweet jumps. The black loop will keep your heart pounding from both hard short climbs and thrilling descents. Fountainhead will put a smile on your face that will last for days.
The series of loops is designed for clockwise traffic. Helmets are required and the Park is closed after dark. The trailhead is clearly visible from the parking lot, 0.6 mile from the park entrance. Please be aware that it is easy to pick up significant speed on all sections, even beginner and intermediate loop, so please ride with caution, especially your first time out. The EMS are at this park on a regular basis.

Access Notes: Please remember that access for mountain bikes at Fountainhead is a privilege not a right. Ride only on marked trails, do not cut through switchbacks, and do not alter trail features. Cutting trails or building obstacles without permission of the park is strictly prohibited and can jeopardize access for all.

History & Background

For more than eight years, local riders have enjoyed the MTB Trail at Fountainhead Regional Park. With the support of the Northern Virginia Regional Park Authority and built through the cooperative effort of MORE, REI and support from the now defunct FAT City Cycles, the trail opened in 1997. Lifetime MORE member Andy Caruthers along with current MORE members Paul Hardy and Larry Cautilli are significantly responsible for the existence of the trail. Featured in the August 2001 issue of Bike Magazine, the Fountainhead trail is described as, "some of the region's most challenging singletrack."

Does anyone have a turn by turn on how to do this 12.9 mile loop? Sep 6, 2018
@Jeffrey Brown - From the parking lot, there is one "main entrance" to the trail which starts you off in the Green loop. At some point (about 1.5 miles in) you will get to a fork in the trail with a bridge on top, and your choice will be go left under the bridge for Blue loop, or go right onto the bridge to continue Green loop (which takes you back to parking lot for a total Green loop of around 3 miles). At this point, if you followed Blue loop, you will be faced with some steep climbs before you get to the fun stuff, a skills area, and some nice flowy sections, before you eventually reach "the picnic table" (yes, there is only one) which is about 3 miles in from the start. Now you have another choice... continue on Blue Loop (which takes you back to Green Loop, which takes you back to the parking lot), OR you can enter the Black Loop (there is a can't miss sign that says "For Advanced Riders only"...:D). If you take the Blue Loop to start heading back, your total mileage by the time you are done will be about 7-ish miles (that is combined Green/Blue). If you take the Black Loop, be prepared for tough climbs, technical features, steep drops, rock gardens, etc.... some of which can't be bypassed. The Black Loop by itself is 7+ miles and will bring you back to the picnic table when you complete it. At which point, you follow the Blue Loop and Green Loop to go back to the parking lot. Total mileage if you do it as follows: Green to Blue to Black to Blue to Green == about 14 miles. Sep 28, 2018
won't let me post the video because of the file format but green, blue, and black loop clips in order.… Oct 18, 2018
