We are excited to have once again secured the remote Weldon Spring Conservation Area and its excessive trail system for our 2024 MammothMarch 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.

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!
