Is the road to Mount Bross in CO unpaved?

Set high in the Mosquito Range of the Rocky Mountains of North America, the road is totally unpaved. It’s an old mining road called County Road 787 (also known as Windy Ridge Road). The ‘legal’ drive ends near the Mineral Park mine in Dolly Varden Gulch. The trail is relatively easy for most of the way. As you near the top, the trail becomes narrow and is made up of mostly loose rock. Full-size vehicles should not attempt to drive all the way up, as there are a few very narrow spots that are very high.

Is Mount Bross still closed?

The summit is private property, and the landowners have not consented to allow climbers to reach the actual high point since 2005. Mount Bross is covered with old mining roads and claims, part of Colorado's historic mining legacy, so there are property issues to consider when hiking up the mountain. The trail is clearly marked about 150ft from the summit prohibiting motor vehicles, so please do not drive all the way to the top.
