Bear Peak is the most prominent mountain along Boulder's foothills. The 7-mile hike takes an estimated 4 to 7 hours and gains roughly 2,500 vertical feet. It's a challenging hike, but most subscribers to this site who are in shape should not encounter much difficulty. The peak is at 8,400 feet, so the oxygen depleted air is not too thin at the top, relative to many other ascents. Take a look at the website for starting points. The trail head begins at the top of Table Mesa Drive at the National Center for Atmospheric Research (NCAR), between Eldorado Springs and Chautauqua Park.
