Сycling Boulder: The Colorado Hidden Cycling Mecca

Colorado’s passion for cycling is legendary, with Boulder standing out as the state’s ultimate hub for enthusiasts. From its extensive network of city bike paths to the exhilarating canyon climbs, cycling isn’t just a pastime here—it’s ingrained in the city’s identity. With breathtaking views and a plethora of renowned routes, Boulder offers a cycling experience like no other, ensuring that no ride is ever the same. 

One standout challenge is Mount Blue Sky (formerly Mt. Evans), boasting the title of the highest paved road in North America. This grueling 45 km ascent to 4307 m above sea level isn’t for the faint-hearted, though a midway parking lot offers respite for the less adventurous. Boulder also caters to casual cyclists with its bike-sharing program, boasting around 50 kiosks scattered throughout the city. Riders can conveniently grab a bike for short jaunts, exploring the scenic landscapes before returning it to any kiosk when done.

When to Go

Boulder, situated in the high desert at an altitude of 1655 meters above sea level, enjoys a mild climate characterized by low humidity during both summer and winter.

July typically sees the warmest temperatures, reaching an average daytime high of 30°C, though evenings may require a sweater due to occasional dips in temperature. Conversely, January marks the coldest month, with an average daytime high of 7°C. Snowfall averages 226 inches annually, necessitating visitors to the Rocky Mountains to dress in layers to adapt to varying temperatures.

Spring brings forth a vibrant display of tulips along downtown Pearl Street and flourishing hiking trails adorned with delicate wildflowers. Despite temperatures soaring into the 80s, snow in May is not uncommon, emphasizing the need for preparedness. 

Summer unveils Boulder’s natural beauty with lush trees and clear blue skies, while autumn paints the landscape in gold, red, and yellow hues. Although snowfall is infrequent in winter, Boulder offers many activities to keep visitors engaged should the occasion arise.
