Visit Boulder: plan your trip with verified accessibility info!

The best time to visit Boulder is arguably spring or fall, when the temperatures are in the 60s and 70s Fahrenheit (16 to 23 Celsius) and there are plenty of festivals and events happening throughout town. But rest assured, Boulder has a climate that's mild year-round and there’s almost always something fun happening. In the summer, there’s a full calendar of outdoor events and festivals in town and an energetic buzz to the city. In winter, there's a peaceful, easy feeling that hushes the city, the Flatirons can be dusted in snow, and warm, sunny days still abound.

Boulder is a true year-round destination. If moderate temperatures, an average of 300 sunny days per year and beautiful scenery sound like the perfect vacation backdrop, then you will love Boulder, Colorado.

Boulder turns every shade of gold, red and yellow in fall. It's rare that you'll find Boulder buried in snow in the winter, but even if you do, there's still plenty happening in the city to keep you busy.
