Boulder Facts


Boulder is nestled in the foothills, where the rolling plains meet the Colorado Rocky Mountains, centrally located near Denver, Denver International Airport, Eldora Mountain Resort and Rocky Mountain National Park. Downtown Denver is just 30 minutes away. Being a few hours from many of Colorado's world-famous ski resorts makes Boulder the ideal Colorado destination.

Land Acknowledgement

Visit Boulder acknowledges that the land on which we live, work and recreate today has been inhabited by Indigenous people for more than 13,000 years. We honor the Núu-agha-tʉvʉ-pʉ̱ (Ute), Hinono'eino (Arapaho) and all other nations associated with the Boulder Valley, affirm their ancestral ties to their homeland and acknowledge the history of mistreatment and forced removal that has had a devastating impact on their communities. When we discuss Boulder with visitors and our communities, we are discussing Native lands, and we endeavor to do our part to include the stories of the area’s first inhabitants.
