Adler-Fingru Open Space is a 55.7-acre area that was once used for crop production and livestock grazing. Ownership of the space is divided three ways among the cities of Boulder, Louisville, and Lafayette. This property is under an agricultural lease, so access to the public is limited to only the Coal Creek Trail that passes through the space.

Bald Eagle Nest Viewing Area

Highlight • Viewpoint

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.
