Mark your calendars for Saturday, October 10, 2026, because the biggest off-road party in Eastern Iowa is returning to Sundown Mountain Resort and it's going to be bigger, muddier, and more epic than ever. Get ready for a full day of hitting the trails, rock crawling, obstacle challenges, mud-slinging action, live music, delicious food, and unforgettable memories with fellow off-road enthusiasts. Whether you're bringing your rig, riding shotgun, or just coming to soak in the atmosphere, Mayhem on the Mountain will be the place to be this fall.
Make it a weekend with primitive camping on Friday night! Spend the night before with us under the stars, around the campfire, to wake up to hitting the trails with off-road fans who know how to have a good time.
Registration opens later this summer, but we are currently accepting VENDOR applications (trade show, food trucks, and bands) and still have a few SPONSOR opportunities available. Want to be a part of the fun? Reach out to us at [email protected].
The countdown to mayhem starts now!
