Apex is great...and include the Enchanted Forest loop while you're at it. Also really good is the Colorado Trail when you pick it up from Waterton Canyon. It's a bore getting to it (I think it's about 7 miles up a dirt road), but it's worth it once you hook up on it. Mount Falcon's a good uphill grind, but it's kinda boring coming back down. Also good is Bergen Peak (sp?), up in Evergreen.Tom Church said:
Never did any lift runs, but I'd bet Winter Park is pretty good. And, there are also a lot of good "regular" riding near there, too.
