What the above Texas Folks said! :)
It's a beautiful drive and Wolf Creek Pass, though steep, is not quite as bad as the old stories from back in the day, before improvements were made. And Pagosa Springs is a great place to spend some time, the hot springs there are well worth the stop.
As an alternative route, just as beautiful and a bit shorter, consider taking US 285 south from Alamosa to Antonito. There you can spend some time looking at the trains for the Cumbres and Toltec Railroad, and consider taking that train journey from Antonito to Chama and back, if you have the time. Another diversion that is well worth it.
If you don't have the time, you can just continue on via CO 17 to Chama NM, crossing over La Manga and Cumbres passes, both ~10000 feet, but not difficult. Some minor curves approaching the top of La Manga, that's about it. Also some great photo ops at the top of Cumbres Pass, where the C&T Railroad crosses as well, if the timing is right you can get spectacular photos of the train up there. Then drop down into Chama NM, you can also see the trains there as well, and check out the sights in Chama -- it's a funky little town.
