For one of the most breathtaking views in the Rockies, you have to take the eight-minute gondola ride up Sulphur Mountain. Once you glide over the treetops to the summit, a whole other world opens up. You can wander along the ridgetop boardwalk to a historic weather station, which involves a few stairs but is more of a scenic stroll than a hike. The 360-degree panorama of six different mountain ranges from the observation deck is something you won't soon forget. It's an absolute must-do, offering incredible photo opportunities and a true sense of the scale of the mountains around you.
