I biked up Corona Pass on 1/1/2016.
What’s Corona Pass?
Corona Pass, also known as Rollins Pass, is a high-altitude mountain pass in north-central Colorado, between the towns of Winter Park and Nederland. Part of the Moffat Road, Rollins Pass was the first railroad passage over the Rocky Mountains, before the Moffat tunnel was opened in 1928. The pass was used by railroad traffic from the early 1900s through 1928, and then thereafter has been used mostly as an scenic automotive drive.
In the summertime, I bicycle up Corona Pass several times a season. It’s great to get above the tree-line on a bicycle, and the pass road itself has access to many great single-track trails such as Broken Thumb, Twisted Ankle, and Rogers Pass.
In the winter, the road turns into a snowmobile heaven. The Grand Adventures company has the USFS permits for grooming much of the trails in the Fraser Valley, and Corona Pass is one of the major roads for their service (and for public use as well). As a result, it turns into a great road for fat biking in the winter. I’ve ridden this pass in Winter a couple of times each season, and it’s always been a blast.
This ride had been my New Year’s Day plan for a while, but it almost didn’t happen. It got down to -20ºF overnight at my place, and in the morning it wasn’t really warming up. But, thanks to some weather sorcery, it was actually warmer closer to the mountains. I left 90 minutes later than planned – at 11:30am it was -11ºF at my place, and 15 miles away at the start of my ride it was a whopping 8ºF. Cold, but certainly bearable, especially on such a bright sunny day.
The road was in great shape on the way up – groomed, snowmobiled, and packed in well.
On the way down, enough snowmobile traffic had come up during my ride that the snow was really chewed up. In some respects that made for a better descent, as I had to pedal just enough to keep my heart rate up and that kept me from freezing as much.
The ride up took 2hrs 50min to cover 9 miles, with 2200 ft elevation gain with a 4.4% average grade. The descent took just an hour.
This was the first time I made it all the way to the top of where the snowmobile traffic goes. What a great adventure, and great way to start 2016.
