About Us


Mud Fest, formerly known as the Foster Mud Flats and Mountain Mud Festival, is a well known four wheel drive event in Sweet Home, Oregon. From an outsider's point of view the event could look like nothing more than a muddy free-for-all. Nevertheless, when digging deep into the heart of Mud Fest, it is easy to see the admirable results that our muddy play day offers its participants, the sport, and the community. What began as an association play day around 40 years ago has now evolved into a widespread demanded event that we are very proud of. Our play day, with its many events, allows families and complete strangers to come together and enjoy the great outdoors and the sport of four wheeling.


Mud Flats

It began as the Foster Mud Flat Races at the Foster Reservoir in Foster, Oregon near Sweet Home. The event was held on the gooey lake bottom after it had been drained for the winter. The Foster Mud Flat Races offered large bog holes, a drag strip, and miles of soupy mud. It was impossible to leave the event without something being muddy, if not everything including yourself. Nevertheless, times changed and in 2001 the U.S. Army Corps of Engineers refused to grant a permit to hold our event on Corp property. Frustrated, but not willing to give up tradition, we looked elsewhere for property to hold our event.

Mountain Mud

Our organization then found private property on Berlin Road in Sweet Home to hold our highly demanded event. Permits were granted at this alternate location and the 2001 event, known as the Mountain Mud Festival, was held without missing a single year. Although the terrain of the original Foster Mud Flats can't be recreated, this new location offered its own greatness maintaining the same event format as the late Foster Mud Flats. The Mountain Mud Festival offered a drag strip, obstacle course, rock crawl, bog holes, pits, acres of muddy terrain to hold it down, and a hill climb that the Foster Mud Flats did not have. It also offered a concession area with food and event merchandise for all to enjoy.

In 2010, our event was held at yet another new location on private property in Sweet Home, Oregon and again evolved.
