At 13,794' Square Top Mountain is the 111th highest peak in Colorado. Situated in Colorado's Front Range, near Guanella Pass, Square Top lies midway between the 14er duos of Evans-Bierstadt and Grays-Torreys. Overshadowed by these loftier neighbors, Square Top attracts relatively little traffic from alpine travelers.
Square Top is best characterized by its large summit area. A set of ridges rise from four directions to meet at the east and west ends of a broad summit ridge that runs for nearly half a mile with a vertical relief of less than 100 feet. Viewed from the north or south, a square top it is. The slopes below this defining summit harbor a large expanse of gentle tundra and several fine alpine lakes. Numbers of mountain goats have also been known to take up residence in the vicinity.
An easy ridge hike from Guanella Pass is the usual route for Square Top. Generally good access to the trailhead makes this a mountain that can be climbed year-round. Strong winds from the northwest sweep snow from a good portion of the route making it a safe outing for those with relatively little winter training.
The trailhead is accessible from either I-70 or US 285 west of Denver. From I-70, leave the interstate at Georgetown (Exit 228 on I-70) and follow the signs for 10 miles to the pass. From US 285, exit at Grant and drive for 12 miles to the pass.
No permits are required for hikes in this area.
Square Top is climbed year-round, but optimal conditions generally occur from late June through September. Be aware that this also the season for afternoon thunderstorms in the Colorado mountains. Hikers should plan to be on the way down by noon.

Note, if you are hiking this mountain in the spring or fall be prepared for all kinds of conditions. When I hiked Square Top it was warm from the start. Then once I got on to the open ridge it became windy with tropical storm like gusts. I had to get out my face masks and winter gloves out (in mid October). Then on the way down on the SE ridge we were shielded from the wind and was able to take off some layers again.
