About us
Thanks for being a part of our Meetup group, and AMC Boston 20s and 30s. For those of you who are new, this email is to give some basic information about how you can get more involved with us and get on even more trips (our other websites have more trip postings than you’ll find here on Meetup!)
AMC Boston 20's and 30's is a group of the Appalachian Mountain Club (AMC), dedicated to encouraging people in their 20s and 30s to get involved in the AMC and enjoy the outdoors.
With many volunteer leaders and co-leaders, we offer a variety of activities and events (both online and in-person). You may find us leading day hikes, backpacking, social events, local walks, trail maintenance, conservation work, kayaking, mountain biking, bicycling, skiing, camping, ice skating, and other activities. We sponsor trips throughout the year, most of which involve exploring different regions of New England. Check out some photos of our activities here!
If you want to be kept up to date with even more of our events, be sure to check the official postings at activities.outdoors.org. We do cross post some events to meetup but you have to register via the link in the description (signing up on Meetup does not approve you for the trip).
There are other ways to stay engaged with us.

20s-40s North and South Twin - Fast Paced
Location not specified yetActivity Type: Hiking, Local Walks, & Trail Running | Hiking
Difficulty: 6 - Strenuous
Trip Leader(s): Ian Baker, Richard Rosenblum
Registration Type: Application
Please Click Here to RSVP: https://activities.outdoors.org/a5UVX000001BQ8H
Register By: 8/30/2026
Audience: 20’s & 30’sDescription: Trip Description Join us for a marvelous day hike to North Twin (4760’) and South Twin (4902’). Our route will be an out and back hike, ascending North Twin via the North Twin Trail, continuing to South Twin, then retracing our steps back to the trailhead. Expect an approximately 10.9 mile out-and-back hike with approximately 3,650 ft of elevation gain at a moderate - fast pace.
Weather-permitting, participants can expect gorgeous views from the open summit of South Twin, as well as water crossings, rocky terrain, and excellent vistas along the way! Prospective participants should have completed a hike of similar elevation gain and distance within the last 6 months and have maintained a vigorous cardio/HIIT workout regimen during the winter months. To address unforeseen challenges such as adverse weather, unacceptable trail conditions or excessive crowding, the planned trip destination, activity and/or meeting place and time may be modified. In that event, participants may elect to join in that activity or opt out.
Hike Plan Our route will be an out-and back hike. Gear List All gear necessary for early summer hiking in New Hampshire. This includes hiking boots or equivalent footwear, multiple layers of non-cotton clothing, at least 2.5-3 liters of water, and enough high-calorie, quick-to-eat food for a full day on the trail. Hiking poles are highly recommended, as there will be one particularly challenging water crossing. Conditions in the White Mountains can change rapidly - bring insulating layers, rain layers, and sun protection as appropriate. The gear list below for 3-season day hikes is a good starting point: https://hb.amcboston.org/images/docs/Gear_lists/Spring_Dayhike_gear_list.pdf
Screening Requirements: Fitness Looking for similar elevation gain and distance in the White Mountains or other similar mountain ranges (Maine 4,000 footers, Green Mountains, Adirondacks. Note that the Catskills, Western MA, southern NH, etc. tend to feature less aggressive terrain) AND a high level of physical fitness. Running, distance cycling, HIIT etc. are good activities. Lower-cardio exercises like bodybuilding weightlifting, city walking, yoga, etc. are generally less effective at preparing for hiking. Goal is to complete the hike under 7 hours for a pace of over 1.7mph+Reminder: Please click the RSVP link above to register!
