The road up Mount Blue Sky may need a reservation

The scenic byway up Mount Blue Sky from Idaho Springs uses a timed-entry reservation system during the busy season, so a visit takes planning.

Published June 10, 2026 - Last verified June 11, 2026

The paved road that climbs from near Idaho Springs to the top of Mount Blue Sky is one of the most striking drives in Colorado. It is also not a place you can just show up and drive any day in summer.

During the busy season, the Forest Service uses a timed-entry reservation system for the Mount Blue Sky Recreation Area and its scenic byway. That means you reserve a window ahead of time rather than arriving and hoping. The goal is to cut down on crowding and long waits at the entrance.

A few things worth knowing. The mountain was renamed Mount Blue Sky, so older maps and signs may still say Mount Evans. The road climbs to very high elevation, where weather changes fast and snow can close the route well outside winter. Cell service is limited, so it helps to download or print a reservation before you leave town.

Reservation systems and seasons change from year to year, so do not rely on what a friend did last summer. Always check the current details before you go.

For the byway’s reservation rules and season, see the Arapaho and Roosevelt National Forests and the official reservation page.
