MammothMarch is coming to Boston!

We are excited to welcome you to Wompatuck State Park, Massachusetts!

Hike 20 miles in 8 hours through one of South Shore’s hidden attractions, located just 20 miles south of downtown Boston.

Our single-circuit hiking loop provides everything this undeveloped and heavily wooded State Park with its 3,500 acres of forest, streams and ponds has to offer.

Mastering our challenge, you will be exhausted, but proud and happy... as well as part of our amazing community of nature-lovers, hikers and MammothMarch addicts!
