Lift accessed mountain biking or Mountain bike park is a summer activity that is spreading all over the world. Using the chairlifts or gondola lifts at a ski area, mountain bikers can get up to higher altitudes quickly. The bikers don't have to ride up, and the ski area operators can keep the hill more profitable during the summer. Most bike parks have a mix of dirtjumping, downhill, enduro and freeride terrain on the trails.
