I'm with John V. Highway 14 up the Poudre River Canyon is a great ride and shouldn't be missed. Very scenic, nice twisties, traffic is usually not as heavy as Highway 34 or P2P, and you may see Moose around Ranger Lakes or Walden.
Also, Highway 134 over Gore Pass is one of my favorites. If you go that way, when you get to 131 make a right and stop at the gas station/bait shop/hunting shop/ice cream store/liquor store in Toponas. Lots of pictures of motorcycles on the wall and nice owner. It is only about a mile up the road. It has been a few years since I have been by there, but used to be a regular stop to cool off on a hot summer day. Then turn around and head south on 131 toward I-70.
