MammothMarch returns to Northeast Florida on January 30, 2027, where Dunns Creek State Park will once again kick off our season of hiking events. After another sell-out in 2026, the event is back.
Located south of a sharp bend in the St. Johns River, more than 6,200 acres of natural communities are represented in Dunns Creek State Park, making it a home to our iconic 20-mile adventure.
Tucked between Jacksonville, Orlando and Gainesville, and about 90 minutes from either city, Dunns Creek makes for a picture-perfect winter hiking getaway in Florida.
Master the challenge and spend a day hiking 20 miles at a stretch. Finishers receive a finisher medal and join our community of nature-lovers, hikers and MammothMarch fans.
