Gateway Mesa Trail Project

Discover Gateway Mesa Open Space

The Parks and Recreation Department is partnering with Volunteers for Outdoor Colorado (VOC) this year to help us construct phase 1 of a new two-mile soft-surface trail extension to the existing Chuck’s Loop Trail at Gateway Mesa Open Space. The trail will be designed by the Town Trails Planner and will be built by volunteers coordinated by VOC with support provided by the POST Partners Volunteer Program. VOC is a statewide organization that provides a volunteer workforce for outdoor stewardship projects, including invasive species management, habitat restoration, recreational improvements and trail construction and maintenance.

Volunteers needed - Three opportunities to help this year! 

We need your help; sign up as a volunteer today! Participants must be at least 14 years old. Minors under 16 must be accompanied by an adult who is 21 or older. Tools and gloves will be provided, as well as food and water. Pre-registration is required for all three volunteer opportunities.

Gateway Mesa Open Space and Trail

Gateway Mesa Open Space consists of 276 acres of grassland mesa and a mixed coniferous forest near the eastern boundary of Castle Rock. This open space area is open to hiking only. The existing 1.6-mile Chuck’s Loop Trail, named for the previous owner of the property, travels around the flat open grassland-woodland habitat, with sweeping views of Franktown and the Mitchell Creek Canyon area. Hikers can currently connect to Mitchell Creek Canyon Trail on the east side of the loop. 

The new trail extension will provide users with access to the unique northern forested portion of the property. This area is completely different from the dry, flat mesa; it is composed of dense mixed mature spruce, fir and Ponderosa pine trees, a few drainages, plunge pool wetlands, steep open scrub-covered slopes and interesting rock formations along with ferns and rare mosses growing in the area. The final alignment will likely include small drainage crossings and rock or timber steps. Due to the length of this extension and the terrain, this project may occur in two phases.  

It’s important to note, the main parking lot at Gateway Mesa will be closed for these work days.
