The Mosaic Outdoor Mountain Club of Massachusetts is a unique non-profit organization dedicated to bringing Jewish people together to enjoy and foster a greater appreciation of the outdoors. We are a volunteer-led, member-driven organization who invite you to partake in a variety of activities with other Jewish outdoor enthusiasts. We welcome singles, couples, and families with children, regardless of age, background, physical ability or religious denomination, but you must be 21 or older to join our Meetup group.
