Within the City of Westminster, there are approximately 120 miles of trails, most of which wind through the open space and provide access to magnificent views, wildlife corridors, and natural beauty. There are five regional trails, 15 loop systems, 12 park loops, plus minor trails that, when combined, add up to 50 different trails within the system. The five regional trails include Big Dry Creek Trail, Little Dry Creek Trail, Farmers’ High Line Canal Trail, U.S. 36 Bikeway, and the Rocky Mountain Greenway Trail. Get more information on trails.

In 1985, voters in Westminster approved a sales tax specifically earmarked to acquire and preserve open space. At that time, Westminster was the second municipality in Colorado to implement an open space program. Since then, Westminster has preserved over 3,700 acres throughout the city and has accomplished the original goal of preserving 15% of the city’s land area. This accomplishment demonstrates the city’s commitment to preservation, conservation and resource sustainability.
