Thanks for tagging me @REI-JenK . I don't belong to a formal hiking club. It's just an informal group of friends. We have, however, participated with some local groups on various occasions. Not sure exactly where you're located, but here are some groups that might be of interest.
We are close to the PA line, north of Baltimore, and some southern PA groups we've hiked with, and done trail maintenance with are: LancasterConservancy.https://www.lancasterconservancy.org/ ; York Hiking Club https://www.yorkhikingclub.com/
Central PA Conservancy http://www.centralpaconservancy.org/
And in the DC area there is the Wanderbirds. http://www.wanderbirds.org/
And if you are more informal, like us, feel free to reach out.
one or more gifts or other benefits from the co-op.
There are several well established backpacking groups in that area, look at meetup.com and the local Appalachian trail club.
Hey @ErinH ! Great that you're checking out local backpacking! In reference to @Philreedshikes 's recommendations (excellent choices Phil), Here is the local PATC home page. The Potomac Appalachian Trail Club is our local AT club that covers over a hundred miles of the AT. While they, too, are experiencing some organizational challenges amidst our current environment, they're another good place to start to find out where the local groups are. We partner extensively with them in some of our in-store programming. Good luck, hike on!
