Best time to visit Denver

Denver has a way of feeling fresh no matter when you visit. From mountain views to city festivals, each season brings a different side of the city to explore.

  • Spring (March – May): As the snow melts and temperatures warm up, trails start to bloom and patios come back to life. It's a great time for hiking, day trips and catching Denver before the summer crowds roll in.
  • Fall (September – November): Cooler weather and golden aspens set the scene for crisp hikes and scenic drives. The city feels calm and cozy, making it perfect for exploring parks or sampling seasonal menus.

Keep in mind:

  • Summer (June – August): Summer brings long days and a packed events calendar. It can get warm in the afternoons, but mornings and evenings are ideal for festivals, rooftop drinks and neighborhood strolls.
  • Winter (December – February): This is the jumping-off point for Colorado's world-class skiing and snowboarding. While you might catch some snow in the city, it's also a quieter time to enjoy museums, breweries and cozy indoor spots between mountain trips.
