Mid Atlantic Climbers (MAC) is a 501c3 non-profit organization dedicated to preserving access to climbing areas in the Mid-Atlantic region, while promoting responsible climbing and environmental stewardship. MAC serves as a liaison between the climbing community and land managers (park and private) for the crags in our region. There are tons of fantastic after-work crags and awesome weekend spots in our area, and it’s our mission to look out for them.

MAC is an Access Fund affiliate, and works closely with other outdoor recreation and stewardship organizations to build community and show our local crags some love.

MAC was founded in 2002 by Thompson Ling under the name DC Metro Climbing, a group focused on stewardship events and access issues within Maryland and Virginia. Thompson partnered with Ocean Eiler in 2006 and went on to launch MAC with a small group of dedicated climbers who were committed to ensuring access while leaving our crags better than when we found them.
