The new Fourmile Mountain Bike Park features 3.5 miles of professionally-built trails with progressive jump lines ranging from beginner to advanced.
"The flow trails have the typical tabletops, rollers, and berms — all common features in trails, but these features are new to the Des Moines area," said Adam Fendrick, Park Planner for Polk County Conservation.
While the trails are relatively flat, they're still "designed to accommodate riders of all skill levels," according to Aaron Steele, owner of Tailored Trails. "There are multiple cross country trails for beginners, and then there are four downhill trails with varying levels of difficulty to allow riders to improve their skills and work their way up to the black diamond lines in the jump park."
