You can take 14 through Ft Collings over Cameron Pass to Walden and then drop down as well. I grew up in northern CO and haven't bothered with 70 for decades. It went to hell when the built Vail in the late 60s and early 70s.
I am just picking up old news from that area , but the monsoons this summer have closed many of the highways and FS roads for brief periods. 125 south out of Walden was closed a few weeks ago with debris and flooding. Am sure they are passable now though. The two big fires up there last fall has put a ton of ash and debris into the drainages.
