Is the Trail Open?

  • Section A of the Billy Goat Trail often closes due to flooding. Under normal conditions, the trail is closed when the gauge at Little Falls reaches 5 feet and reopens when the gauge falls to 4.8 feet. However, under certain circumstances, the trail may be closed at lower levels.
  • Please check Current Conditions before your trip to confirm the trail that you want to hike is open.

Choose Your Trail

Located southeast of Great Falls Tavern Visitor Center, in Potomac, Maryland; The Billy Goat Trail, one of the busiest trails in the DC area, contains three different sections that total eight miles, each section begins and ends on the towpath. The Billy Goat Trail provides fun and adventure for all ages.

Section A

Level: Technical and Strenuous
Length: 1.75 miles one way
Pets: Not permitted
Closest Parking: Great Falls Tavern Visitor Center


The hike involves scrambling over angled rocks, boulders and climbing. Visitors in less than optimal health, visitors with small children, and visitors not experienced or properly outftted should consider other trail options. The 1.7 mile hike takes most visitors 2-3 hours to complete. Along the trail are views of Mather Gorge and Potomac River. This trail can close due to fooding from the river.

Recommended ONE-WAY going downstream:
  • Start at the upstream entrance near Great Falls and end downstream near Anglers
  • One-way travel reduces the number of encounters with other visitors
  • One-way travel prevents hiker "jam-ups" at the Traverse and other narrow areas of the trail
  • One-way travel protects natural habitats
  • The Exit Trail (half way point) will still be two-ways, so hikers can choose just the top half or bottom half of the trail.

Section C

Level: Easy to Moderate
Length: 1.6 miles one way
Pets: Permitted
Closest Parking: Carderock Recreation Area


River views and a small waterfall are encountered on this trail. Although there are a few rock outcroppings, most of the trail is wooded.

What to Bring

  • Good, comfortable, broken-in, hiking shoes that grip well on rocks and hills. The majority of injuries—sprained ankles, tweaked knees, and falls—happen because people did not wear good shoes.
  • 64 oz (2 L) of water per person
  • Snacks
  • Suncreen and a hat
  • Map of Hiking Trails
 

Proceed with Caution

  • Don't become a statistic. There are over 400 emergency rescues each year on the Billy Goat Trail.
  • Cell phone reception may be unavailable.
  • Wading and standing on rocks at the water’s edge are extremely dangerous. One false step can have dire consequences. Fines of $200 or more may be charged for swimming in the Potomac River along the trail. If you’re interested in learning why this part of the river is so deadly, check out this article in the Washington Post.
 

Parking

  • Access all three of the sections from the towpath between Great Falls Tavern and Carderock (Anglers is between section A and B).
 

Leave No Trace

  • Protect fragile plants by staying on the trail.
  • Follow the blue blazes that mark the path.
  • Hike in small groups.
  • Take nothing but pictures and leave nothing but footprints. This is a trash free park. If you pack it in, pack it out.
  • Observe wildlife from a distance. Do not follow or approach them.
  • Never feed animals. Feeding wildlife damages their health, alters natural behaviors, and exposes them to predators and other dangers.
  • Respect other visitors and protect the quality of their experience.
  • Be courteous. Yield to other users on the trail.
