Natural Areas and Trails
Greeley’s natural areas and trails connect the community to nature.
Upcoming Closures
Arroyos del Sol Natural Area and Missile Site Park will close for the winter on January 2, 2026. They will re-open on April 1, 2026.
Closing the natural area for the winter allows wildlife a much-needed respite during the difficult cold months. Animals like deer, turkeys and coyotes are awake, active and expending energy all winter long. Giving them space to rest allows them to use their energy reserves to stay warm and find food and shelter.

Mowing and Vegetation Management
An inter-departmental team of City staff created the Clean, Safe, and Beautiful Standards, which guide vegetation maintenance for non-irrigated city properties. Natural Areas and Trails follow the standards as outlined below.
During the growing season, a 3-4 ft swath is mowed on both sides of the trail to a height of 6 inches and maintained at no more than 12 inches. This trailside mow is completed on both paved and soft surface trails. This helps with visibility and avoids vegetation on the trail surface. Single-track trails are not mowed.
Native vegetation within the interior of natural areas is typically left standing at its natural height unless management actions (i.e., weed management) dictate otherwise. If you encounter an area that needs attention, please call or email us.
Trails Master Plan Update
Greeley is growing, and with it, the need for more attention to our trails. The Trails Master Plan Update, adopted in 2025, identifies the top priorities for trail construction and future trail connections.
Get Outdoors Greeley Plan
Adopted in 2021, the Get Outdoors Greeley Strategic Plan provides a 5-year strategic framework for natural areas, open lands, and trails throughout Greeley. The plan lays out goals, objectives, and a work plan for future acquisition, restoration, long-term stewardship, capital projects, and sustainable funding of priority conservation areas and visitor infrastructure.
