Rollins Pass (also called Corona Pass on the Grand County side) is an anthropologically significant mountain pass that sits roughly 5 miles east of Winter Park, Colorado. The pass’s rich history and frequent use make it known as “one of the most endangered sites in Colorado.”
The area has endured many natural and man-made avalanches and has been traversed for thousands of years. Today, Rollins pass sits on the border between Boulder, Gilpin, and Grand County.
The summer only drive is very difficult and require a high-clearance 4×4. While you can access Rollins Pass either from the East Portal by Rollinsville, south of Nederland, or via the West Portal by Winter Park, you can’t continue all the way in a passenger vehicle, crossing the continental divide.
There is no motorized route that connects across the divide, so plan to go back down the way you came up, either from the east at Rollinsville or west at Winter Park. You cannot drive the whole route from Rollinsville to Winter Park, or vice-versa.
Rollins Pass, which was originally known as Boulder Pass, is named after John Quincy Adams Rollins. John Q.A.Rollins was an extremely friendly and charismatic person who received approval to build a wagon road along the pass in 1866. The history behind the past is actually much deeper, with human travel being traced back over 10,000 years.
Paleoindians are the first known people to have used the pass. The ancient hunters built rock walls, known as game drives, along the area’s ridges to purposely direct the roaming sheep and elk over the Continental Divide at Rollins Pass. Native American tribes continued to build and enhance the game drives, which can still be seen today.
As efforts to connect Denver and Salt Lake City with a railroad increased, Rollins Pass saw its first successfully completed railway in the early 20th century. From 1909 to 1925, the 23 mile stretch across Rollins Pass became infamous for derailments and brake failures caused by the unforgiving weather and alpine conditions. Accidents were significantly reduced when the line was improved with the Moffat Tunnel.
Rollins Pass began to once again see automobile traffic with an unpaved road reopening for recreational use in 1949. The pass also serves as a navigational waypoint for air traffic and is the site of an operating natural gas pipeline, which was built in 1969.
