From late spring through late fall, Oak Mountain's ski trails become mountain biking trails, offering a mix of technical downhill, intermediate and beginner trails. Expect both natural and man-made drops, jumps and berms, as well as easy trails offering gentle slopes, with smooth dirt or undulating terrain. Intermediate trails can be steeper in places and have various natural and man-made features. Expert trails incorporate technical drops and jumps, which sometime have gaps. Terrain is also steeper with technical natural features; such as rock and root gardens.
