Great Falls rock climbing
Use caution while near the river. Swimming and wading are not allowed at any time.
Five miles of trails, including the Old Carriage Road, Ridge, and Difficult Run trails, are open for biking. Biking is not permitted on the Falls overlooks, or on the River, Patowmack Canal, Mine Run, or Matildaville Trails. A bike rack is located behind the visitor center.
Don't forget your binoculars and bird guides! Depending on the season and the time of day, you have a chance of viewing some of the 163 species of birds that can be found here. Among them are waterfowl such as ducks, geese, and herons. Other species include songbirds, woodpeckers, vultures, and kingfishers. This large variety of birds makes Great Falls Park an excellent location for birding.
The American Whitewater Association has current river levels and recommendations for paddling Great Falls, the Potomac River Gorge, and other areas. Go to the River Info tab and search for the Potomac River. If you're searching by state, the Potomac River is located in Maryland.
Be sure to check river levels before you come and know your skill level before attempting to boat on this section of the Potomac. Higher river levels can make boating dangerous, and rescues can be difficult. Swimming, wading, and tubing are not allowed.
Climbing sites begin downstream of Overlook #2 and end near the emergency boat ramp at Sandy Landing. No climbing is permitted in the historic canal cut. Routes range in length from 25 to 75 feet. Difficulty ranges from 5.0 up to the highest rated climbs at 5.14. Most of the routes are in the 5.5 to 5.9 range. All climbing is top-rope and no anchors may be drilled into the rock. Bring enough anchor material to have two independent anchor systems and allow about thirty feet of material from the edge to your anchor and you will be set to move to almost every climbing area in the park. The majority of the climbs are accessible via a walk down route except during periods of high water, above 4.5 on the Little Falls gauge. The river gauge reading is reported in the weather section of the Washington Post under the title 'River Stages.'
Fishing is permitted with either a Virginia or Maryland state fishing license for all fishermen over the age of 16. The park does not issue licenses, but they can be purchased at fishing/sporting goods stores, hardware stores, and some convenience stores. A regulation book for fishing is given with each license issued, although you may need to request one. For more information on the fishing regulations, you may contact the Maryland Department of Natural Resources, which administers the Potomac River. Line fishing is allowed, but net fishing is prohibited.
