Mary Bird Branch Trail is a 1.2 mile lightly trafficked out and back trail located near Triangle, Virginia. The trail is good for all skill levels and primarily used for hiking.
Nice and easy. Park at Turkey Run Campground/Education Center and combine with Quantico Falls/Cascade trail for a longer easy out and back.
When added with some of the other trails in Potomac National Forest, it makes for a good hike. Short by itself, small uphill section (or downhill depending which way you are coming from). Relatively easy.
Short trail did in connection with Quantico Cascade. Didnt see any beavers, maybe they were busy.
Trail is pretty easy.
