        This park offers over four miles of natural surface trails and approximately two miles of hard surface trails. The very popular Cabin John Stream Valley Trail begins at Goya Drive and extends south to Cabin John Local Park. Unless noted otherwise on the map, trails marked “Natural Surface” and “Hard Surface” are “Shared by All” trails which include hikers, bikers, and equestrians.

        The Cabin John Stream Valley Trail starts near the C&O Canal near MacArthur Blvd and goes north to the trailhead at Goya Rd. The portion of the trail from MacArthur Blvd to River Road. has both a biking trail and a hiker-only trail in parallel and is one of MoCo’s best natural areas.

        Heading north you take the sidewalk about 1/4 mile then back onto trail. There is small parking lot on Seven Locks road south of River Rd. and another on River Rd. less than 1 mile west of the Beltway (River Rd exit). Heading north from this point, trailhead are at Bradley Blvd (limited parking), Seven Locks Rd (no parking), Democracy Blvd (ample parking at the Indoor Tennis Center 7801 Democracy Boulevard Bethesda, MD 20817), Tuckerman Lane (Group Picnic Area) and at the northern terminus on Goya Dr. There are three small but fun loops north of Tuckerman Lane by the campgrounds.

        Because the entire trail is within an urban setting, riders must be careful when crossing roads as they carry high volumes of vehicular traffic. A portion of the trail traverses Cabin John Regional Park.

        The trail is not very technical, but the short, intense climbs will test your fitness level (esp below the beltway) and there are a few spots that will test your technical skills. There are some low lying areas prone to flooding and that stay wet unless it’s been weeks between rainfall. These areas are primarily in the River/Bradley section, just prior to Seven Locks. The county has completed some nice re-routes north of Bradley Blvd and Tuckerman Lane eliminating some chronically wet sections.

        Heading north from River Rd, the trail is blazed Blue and next road crossing is at Bradley Blvd. This section has one offshoot trail that will loop back to the main trail and with the exception of two climbs and stream crossings, is flat and fast. The trail continues immediately across Bradley to a short, steep climb with a hard right hand turn at the top that will test your skill. There are offshoot trails in this section, with all either returning to the main trail or exiting the park at a road. As you approach Seven Locks – a nice downhill section, you can either cross a small creek to your left or go right to Seven Locks. No matter which way you hit Seven Locks, turn left towards the traffic light at Democracy Blvd. Cross Democracy, turn right, and the trailhead is 100 yards ahead to your left.

        You are now entering Cabin John Regional Park. There are multiple trailheads as well as trails here with parking. Cabin John Regional Park has amenities such as picnic areas, amphitheater. playgrounds, miniature train & snack bar, baseball fields, ice skating rink, and park headquarters. Exiting the park at Tuckerman, have two options, you go left for about 200 yards and the trail picks up on the right hand side of the road for another mile to Goya on the west side of the creek. Or you can ride the three campground loops on the east side of the creek

        With offshoots, you can get close to 20 miles on an out/back ride.
