Elk Meadow Park, Nature reserve in Jefferson County, Colorado, US.

Elk Meadow Park is a 1,140-acre park of open grassland on the lower eastern slopes of Bergen Peak, managed by Jefferson County Open Space. Ponderosa pines, Douglas firs, aspens and small groves of lodgepole pines cover the slopes, and Bergen Creek and Troublesome Creek run through the meadows. The trail system starts at a small parking area with restrooms and a gazebo.

The land was purchased and protected starting in 1977 by Jefferson County Open Space through acquisition of private ranch properties. This project was part of a broader effort to preserve natural areas across the region.

The trails network supports multiple outdoor activities including hiking, mountain biking, cross-country skiing, and nature observation throughout different seasons.

The reserve can be accessed through two main entry points: the Stagecoach Trailhead and the Lewis Ridge Trailhead, each offering different route options. Trails vary in difficulty, making it suitable for hikers of different skill levels.

The Too Long Trail climbs from Elk Meadow Park into Bergen Peak Park, a conservation and wilderness area of Denver Mountain Parks, and reaches the 9,708-foot (2,959 m) summit of Bergen Peak. The link between the two park systems was arranged cooperatively by their managers.
