Copper Mountain

Copper Mountain is a high mountain peak at an elevation of 3.758m (12,329ft) above the sea level, located in Summit County, in the U.S. state of Colorado. It’s one of the highest mountain roads of Colorado.

Union Mountain

The road to the summit, located within the  White River National Forest, is a chairlift access trail. It’s gravel, rocky, tippy and bumpy at times. Winter comes early and stays late on this trail, so you may only be able to safely run it in the middle of the summer. Great trail for experienced wheelers. Avoid driving in this area if unpaved mountain roads aren't your strong point. 4x4 vehicle with high clearance required. Stay away if you're scared of heights. Expect a trail pretty steep. Wet conditions may make for tough driving along the muddy road.
