The Best Wildflower Trails in Boulder 

Winter Snowshowers Bring Frontrange Flowers 

Blankets of snow have begun to melt in the high country, giving dormant wildflowers a much-needed drink of water. Refreshed, they begin poking their lovely heads out of the ground in April. Soon, a blanket of delicate blossoms will cover the mountainside meadows and forests. Wildflowers will continue to be part of our vistas until the first snowfall in October. But May brings the largest wave, making it an ideal month for hiking and photography. A smattering of wildflowers can be found on almost all of Boulder’s trails. But to help you find the best spots, our Boulder realtor team has put together a guide to the areas with the most wildflower activity in Boulder.


But First— Brush Up On Your Trail Etiquette


Stay on the trail

It’s so tempting to run through a field of wildflowers with your arms open and the sun kissing your face…. But you should know that that’s against LNT principles. Even just walking through wildflower fields tramples the little beauties. We love the wildflowers. We want them to grow back forever! Please stick to the trail. 

Look but don’t pick!

It’s also illegal to pick wildflowers in Colorado. Some are so rare that they are protected by the state. It’s a hefty fine if you get caught, and it endangers their future growth. 

Actually… don’t even touch them

And DEFINITELY don’t eat them! Hopefully, this goes without saying… but it’s important to mention if you’re hiking with a four-legged friend. Some of Colorado’s wildflowers are deadly (some even through touch). To play it safe, wear long pants and boots on your adventure. Larkspur, Death Camas, and the Western Water Hemlock are the most common poisonous local wildflowers to avoid.
