MammothMarch is coming back to Missouri in 2025!
We are excited to have once again secured the remote Weldon Spring Conservation Area and its excessive trail system for our 2025 MammothMarch Missouri edition. Hike 20 miles along a great mixture of diverse trails, such as Katy Trail and Lewis & Clark Trail featuring superb overlooks of the Missouri River.
Our single-circuit hiking loop starts and finishes at the beautiful Defiance Ridge Vineyards, located just half an hour west of St. Louis.
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!
