This packed dirt multi-use trail runs for nearly nine miles, from Lac Amora Open Space to McKay Lake. It links many small lakes, ponds, and streams in Broomfield, and is a great connector for other trails.

After losing their nest to a lightning strike in August, it was unclear which location the eagles would choose for their to new nest. With limited suitable nesting trees in the area—including one along the trail near their previous nest—they have now settled in a tree here, near the southern end of S. 104th St.
