ECMX Park

ECMX Park, officially EC Enterprises Motorsports Park, is a commercial multi-motorsports complex built across a massive hillside above Lewiston, overlooking the LC Valley, and one of northern Idaho's premier event venues. The moto side centers on Track 148, a full-size permanent motocross circuit worked into the rolling slopes, with a separate controlled kids track for youth riders. The 60,000-square-foot FreedomNorthwest Arena hosts the Lewiston Supercross, grand prix events, and demolition derbies, while engineered waterways and bog trenches stage jet sprint boat races and mud bog trucks.

Know before you load the bike: there is no open practice. The facility runs strictly event-only, with riding limited to organized races and structured pre-race practice blocks, typically a Friday evening session ahead of a Saturday race. Racers on the youth track need a specific minor consent form signed in front of an ECMX official or a licensed notary before wheels touch dirt.

As a spectator venue it excels: permanent bleachers plus terraced hillside seating let thousands of fans watch the entire layout from start to finish, with food trucks, beverage stations, and beer vendors standard on event days. Parking runs $5 cash, no outside alcohol comes through the gate, coolers get searched, and the whole property is strictly tobacco-free. Multi-day event entries include dry camping at roughly $25 a night, with no electric or water hookups.

For Lewiston, Clarkston, Moscow, and Pullman, ECMX is the valley's motorsports bowl, and its calendar (including Idaho OTMX National rounds) posts at ecmxpark.com.
