Southern Illinois Fat Tire Festival (FTF) happening again for the 21st year, one of the best MTB events in the entire MidWest! This year’s event goes down October 17-19, 2025, at the one and only Camp Ondessonk located in Ozark, Illinois right in the middle of the beautiful Shawnee National Forest. We have miles and miles of great riding for all levels of riders from mellow flow to rugged all mountain boulder strewn rowdiness. The Midwest’s all-inclusive mountain bike weekend with tons of fun riding; both professionally guided and self-led, amazing food and drink, awesome tree-house accommodations, and tons of outdoor adventures Friday, Saturday and Sunday.

FTF has something for everyone, from those wanting to ride every minute of the day to those tagging along to enjoy some time in the great outdoors. The list of fun evolves each year and is part of what makes Fat Tire Fest such a fun event for EVERYONE. This year the list includes 30+ miles of onsite trails to explore at any time, including the 10+ miles of fun and flowy trails handcrafted specifically for MTB riding that weave thru the 800+ acres of CampO property.
