General Description:

Cabin John Creek is an existing stream valley Greenway which runs from just south of the city of Rockville to connect with the Potomac River. A natural surface trail ideal for mountain biking exists within the stream valley for most of its length. At the northern end of this Greenway is Cabin John Regional Park.

It is a beautiful park filled with tall shade trees, stream valleys, flowers and wetlands. Along the park trails, visitors can see all sorts of wildlife including deer, red foxes, box turtles, bluebirds, woodpeckers, monarch butterflies and a variety of other species. In spring and early summer, wildflowers are abundant.

The park offers many recreational features and outdoor activities including: a nature center, biking and hiking trails, a minature train ride through the park, a playground, athletic facilities and a public ice-skating rink.


The Trails:

The Cabin John Regional Park trails provide over 4 miles of natural surface trails and about 2 miles of paved bike paths. The key trail in the park is the natural surface trail, which continues southward all the way to the C&O Canal.

Cabin John Stream Valley Trail: 8.8 miles (one-way)

The scenic Cabin John Stream Valley Trail runs North-South for 8.8 miles one-way through Cabin John on the Potomac River to Montrose Road & I-270 in Rockville. The trail is open to hikers and bikers (not equestrians) and marked with a sky-blue blaze.

Note: The southernmost 2 miles (from the Potomac to where it crosses under the Beltway - near Seven Locks Road) is not rideable and is not open for bicycling.

Even though the trail is located near major highways and residential areas, it offers a sense of solitude and natural beauty. A portion of the trail traverses Cabin John Regional Park along Cabin John Creek and continues south all the way to the C&O Canal and then extends northward to Goya Drive.

Riders will encounter several small stream crossings, some short climbs and descents, rocky sections and Mountain Laurel thickets which are beautiful when they bloom in June. Because much of the trail travels along the creek, it gets quite muddy after it rains, which leads to trail erosion and deterioration if ridden in these poor condtions. Let's leave these trails to dry unmolested so they will be available to be ridden another day.

Be careful of traffic when crossing roads, especially River Road at the southern portion of the Stream Valley Park. In order to cross at the signalized intersection, trail users must leave the park system and walk along the north side of River Road to Seven Locks Road.
