Flat Nasty Offroad Park

Saturday, December 23, 2023

Other Names

Ozark Mountains, White Knuckle Trail

Last Known StatusOpen

This large offroad park offers over 850 acres of woods trails, a groomed motocross track and panoramic views of the Ozark Mountains. The terrain is mostly rugged with both small and large rock boulders with moderate elevation changes, but there are some sections that are beginner friendly. All vehicle types are welcomed but the trails are geared toward four wheelers and rock crawlers.

Camping is permitted and there is plenty of space for large rigs. There are some sites with electric hookups and a two bedroom log cabin and bunkhouse available for rent (reservations recommended). The property also has a couple small lakes stocked with fish.

The park is open daily year-round during regular and three day holiday weekends. During scheduled special events food trucks, merchant vendors and live music is provided. Call before you haul.
