Boulder sits at 5,430 feet above sea level and, like much of Colorado, is a haven for ski enthusiasts and outdoor adventurers from around the world.

  • Boulder Flatirons
    The Boulder Flatirons are three massive towers of rock dominating the backdrop of the city. The Flatirons are basically huge, flat, and steeply angled slabs of stone that experienced climbers love to tackle. Over 650 established 5th class rock climbing routes have been mapped offering a nearly inexhaustible variety of climbing challenges. Many offer extreme difficulty ratings and plenty of great rappelling opportunities. The Third Flatiron is the tallest at 1,400 feet high. This Boulder behemoth has been climbed in roller skates, in the nude in 8 minutes flat without using hands…all by different climbers, of course! The Boulder Flatirons are accessible from historic Chataqua Park and are surrounded by scenic picnic and hiking spots for the less extreme Colorado visitor. Other great climbing sites include nearby Flagstaff Mountain and Boulder Canyon.
  • Boulder Falls
    Cascading Boulder Falls is located 11 miles to the west of the city and is a wonderful place to spend the afternoon enjoying the natural wonders of the Colorado landscape. The Falls were donated to the City of Boulder along with five acres of mining claims by Charles G. Buckingham to save them from the then encroaching tungsten boom. The Falls are formed as the North Boulder Creek plunges 70 feet down into Middle Boulder Creek to flow merrily on its way. Picture Rock is a favorite Boulder photo spot, with a round hole eroded right through the middle making it the perfect frame for smiling faces!
