Northeastern & mid-Atlantic US - my 200th review and the honor goes to an organization that's close…read moreto my heart, the Appalachian Mountain Club!
I can't believe there aren't more reviews for the AMC, and I don't mean the movie theater. This is the BEST organization if you love the outdoors and live in the northeast!
I belong to the NY-NJ chapter (https://amc-ny.org) but AMC has 11 local chapters also in CT, DE, MA, ME, NH, RI, and the Potomac region (DC, MA, VA).
AMC is the oldest outdoor club in the United States, and works to support and promote outdoor recreation & education, and environmental stewardship.
The organization is filled with wonderful and dedicated people. Its trained leaders and volunteers organize SO many hiking, camping, backpacking, paddling, biking, rock climbing, skiing, snowshoeing, sailing. etc. trips; as well as offer instructional & skills courses, wilderness first aid certification, and fun outdoor events accessible to everyone and at all levels of aptitude - and mostly for free or at low cost!
They also offer incredible guided adventure travel and trekking all around the world to places like Patagonia, the Himalayas, Scotland, Switzerland, Canada, US national parks, Italy, Greece, southeast Asia, the Balkans, Africa, New Zealand, Fiji, etc. etc.
You don't have to be a member to join most of the activities, events and trainings, but membership gets you a significant discount to paid events and trips, as well as 20% off lodging at their huts, cabins, and campsites, and on AMC books/maps & merch. We have a family membership and it's totally worth it.
I've stayed in several of their lodgings but am particularly fond of the Harriman Outdoors Center here in Rockland County, NY - you can rough it or glamp, as it has excellent facilities, and FABULOUS food at their dining hall if you don't wish to give up your creature comforts while taking in some nature.
Events can be searched on their website:

(There's also a way to set up an activities digest email to get notified of new postings, but I leave that for the devoted to find. ;))
The NY-NJ leaders also post many of their hikes and other events on Meetup.com so you can look there for activities to join as well.
There is also a young members group for under 40s.
The groups are very active and often organize multiple events per week. All are welcome!
By the way I don't work for AMC - I'm just a very passionate member and advocate and outdoor enthusiast, and think more people should know about them! (Even as I want to keep this best kept secret to myself lol.)
