If you think Colorado is all about winter travel fun, you haven’t experienced summer at Keystone Resort. Are you a golfer, tennis nut, horseback rider, mountain biker, hiker or mountain lover? You’ll find plenty to do here in the summer. I’m at Keystone Resort in Colorado, for the TBEX travel blogger conference, so this boomer traveler is skipping most of the fun summer things to do in Keystone. But, I’ve seen enough to convince me that a return trip is definitely in my future. Be sure to take the scenic lift ride to the top of Keystone Mountain for a 11,640 ft. view.
