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.

Mud Fest

In 2010, our event was held at yet another new location on private property in Sweet Home, Oregon and again evolved. This current location has the same basic format and proved to be an exciting combination of past events. It possesses some of the most popular individual events that the Mountain Mud Festival offered and has more opportunity for the soupy, gooey mud that the Foster Mud Flats had. So many four wheel drive events make attendees specify being a participant or spectator. Not at Mud Fest.

The Event

Uniquely the Mud Fest accommodates both spectators and participants. The event, usually the first Saturday in March, attracts thousands of attendees and their vehicles. The vehicles range from stock and mild to full out wild. Although no trophies, ribbons, or awards are given to those with the fastest time or most wins, bragging rights are declared just to be challenged at an upcoming event.

Keeping the Peace

To make our event successful, rules must be imposed on our participants. All rules must be followed to ensure future events. Event documents will be available to ticket holders that outline event rules and specifics. Event attendees are required to read and familiarize themselves with the event rules. All rules must be followed.

Event Staff

As individuals volunteering our time, it takes a lot of effort on our part to make the event a success. It takes a lot of prep work to get the land ready for the event in the months prior to the event. After our one day event, the land is returned to its original state. Many do not realize that the event property is developed before the event and returned to its original state afterwards only to be developed once again as the next event time rolls around. Also, in the months following each event, we are in the planning stages of the upcoming event. Event details change every year. Current, up to date information will be available on this website and our organization's information line as details unfold regarding the upcoming event. Feel free to periodically check for updates. We hope to see you at an upcoming event.
