Boulder's Open Space and Mountain Parks offers a vast network of trails and diverse outdoor activities, serving as a gateway to Colorado's spectacular Front Range beauty.
Boulder's Open Space and Mountain Parks (OSMP) is a sprawling area of protected land encompassing over 45,000 acres of natural beauty along Colorado's Front Range. This expanse is known for its dramatic flatirons, meadows, forests, and riparian zones, offering a rich tapestry of ecosystems. With over 155 miles of trails, the OSMP provides ample opportunities for hiking, trail running, horseback riding, wildlife observation, and rock climbing—all within a short distance from the city of Boulder. The area is home to numerous bird species and wildlife, including mule deer, black bears, and coyotes, thriving among its various habitats. Boulder's OSMP is rooted in conservation history with efforts dating back to the 1960s when Boulder residents prioritized preserving open space lands. This commitment to conservation has ensured the protection of its unique landscapes for future generations. The area's visitor appeal lies not only in its outdoor activities but also in the stunning vistas and geological features like the iconic Flatirons, adding to its significance as a local and regional nature haven.
