MammothMarch is back in Massachusetts!
After two sold-out years in a row, we are excited to bring MammothMarch back to one of South Shore’s hidden attractions: Wompatuck State Park!
Join us for a 20-mile hiking adventure on June 6 for one of the nation’s biggest hiking events on National Trails Day 2026 and explore everything the undeveloped and heavily wooded State Park with its 3,500 acres of trails, streams and ponds has to offer.
Located just 20 miles south of downtown Boston, MammothMarch makes for the picture-perfect weekend getaway.
Master the challenge and spend a beautiful day hiking 20 miles at a stretch. Getting your finisher medal, you will be exhausted, but proud and happy... as well as part of our amazing community of nature-lovers, hikers and MammothMarch addicts!
