People who use MapQuest or GoogleMaps to navigate from D.C. or the beltway tend to get lost. The directions below are slightly longer, but easier to follow.

From Washington, D.C. and West

  • Take 495 to Route 4 South (which is Pennsylvania Ave. running out of SE D.C.) and continue about 5 miles. (DO NOT take the Old Marlboro Pike exit from Route 4.)
  • Take the left hand Ritchie Marlboro Road Exit.
  • At the stop sign turn left.
  • At the first stoplight turn left onto Old Marlboro Pike.
  • The farm is just over a mile up the road, marked with a sign reading, "Clagett Farm, Chesapeake Bay Foundation".
  • Turn right on the farm driveway. (If you reach Brooklee Rd or Mellwood Park, you have gone too far)

  • Take the Ritchie Marlboro Road Exit.
  • At the stop sign turn left.
  • At the first stoplight turn left onto Old Marlboro Pike. The farm is just over a mile up the road, marked with a sign reading, "Clagett Farm, Chesapeake Bay Foundation".

Navigating on the Farm

  • Follow the drive around to the first fork and turn left.
  • Turn left at the fork. Buses should head toward the barns ahead on your right and park on the grass to the left of the barns. Cars—unless you spot us on the way, continue to the top of the hill and park next to the garage. Greenhouses should be within sight.
  • We usually meet at the washing station, which is across the drive. If we are not at the washing station we will leave a sign with our whereabouts.

Please bring the Clagett Farm cell phone numbers (301-646-0282 and 301-627-4662) in case you cannot find us.
