The Boston Mountain Grotto is a community of cavers with a shared passion for exploration, adventure, and the natural world. We welcome everyone, from complete beginners to old timers.
As a BMG member, you’ll gain access to a private discussion page, an event calendar, a free library of caving knowledge, and a variety of loaner gear—perfect for new cavers who want to get started without a big upfront investment. Loaner gear includes helmets, lights, suits, packs, pads, and more. Members also enjoy exclusive training opportunities, spanning much of the Ozarks and even nationwide.
Membership dues are $15 per year, with discounts available for multiple members from the same household.
