Hikes in Boulder

Boulder is Colorado’s outdoor playground – a trendy, friendly, fun city nestled in the foothills of the Rocky Mountains. If you’re a fan of the Great Outdoors, this vibrant city has so much to offer, with beautiful mountains, tranquil creeks, deep canyons and strange rock formations just a stone’s throw from the bustling urban center. This wild place has charm and beauty in abundance, with natural riches to rival any other US state. We love it, and we’re sure you will too.

Boulder boasts an impressive network of hiking trails, scattered across the national and state parks that surround the city. You’ll hike in the shadow of jagged Rocky Mountain peaks, with views over gorgeous alpine meadows and lush forests, or descend into stunning canyons, clothed in colorful foliage and carved by rushing waters. Perhaps the most iconic features of this spectacular region are the Boulder Flatirons, steep rock formations that rise out of the landscape and form an important part of the town’s identity. The sheer variety of hiking trails and landscapes on offer makes hiking in Boulder a truly rewarding experience.

Boulder sits at an elevation of 1,655 m above sea level, and many of the hiking trails around the city rise significantly higher. If you’re not used to hiking at high elevations, you may wish to take a little time to acclimatize before tackling the more difficult trails. However, if you’re in training for a Colorado 14er, Boulder is a great place to come to get in shape and prepared for the trail.

When Is The Best Time To Hike In Boulder?

Nestled in the foothills of the Rocky Mountains, Boulder is an ideal hiking destination! Boulder is actually a popular location in Colorado for winter hiking, as the lower-elevation trails close to the city often remain accessible in winter, despite the snow. You may need snowshoes or microspikes in some places, but this is a wonderful way to see the Colorado mountains in the cold season. Although the weather begins to improve in March and April, spring is not the ideal time to hike in Boulder. In fact, local residents call this period the ‘muddy season’, as the melting snow and spring showers make the trails wet, muddy and difficult to access.

Instead, we think it’s best to wait for June and July, when the weather is warm and sunny, and the trails are looking their best. However, summer is also the busiest month of the year, and you may find yourself fighting for space on the most popular routes. As a result, we think that the best time to hike in Boulder is autumn, when the weather is still mild and sunny (if a little unpredictable), and the crowds have dissipated. What’s more, you’ll get the chance to see the forests at their finest, glowing with fall colors.
