The ILSOLC Mountain Bike Skills Park is designed for all skill levels in mind. There are seven miles of flowing single track, a pump track, skill trails (PowerUp Track) and gravity fed flow trails. Local riders compare the park to an amusement park for bikes, similar to riding a roller coaster. The skill trails offer short but some steep climbs, lots of low rollers, quick turns, berms and fast descents. The overall elevation change is minor; however the frequent climbs over the mounds and back up the hill will give your legs a good workout.
This is not purely a playground for those with well-developed leg muscles. There are trails for less-experienced riders starting with a beginner single track loop and skill trail to build confidence. The skill and confidence gained on these trails will empower the beginner to work toward more advanced trails at the park.
