Tips from the Community

Alec B
June 2, 2025, Standley Lake Bald Eagle Viewing Shelter

Cool spot to watch one of the nests.

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.

Cottonwood Creek runs out of Cherry Creek Reservoir and continues south. You cross the creek on several occasions on bridges while following the bike path.

The Big Dry Creek Trail is located in Westminster and spans 12 miles from Interstate 25 to Standley Lake. The multi-use trail features a mostly flat terrain with occasional moderate uphill, passing through open spaces, parks, and neighborhoods. It includes a short on-road section near 99th Street and connects to the US 36 Bikeway, which links Denver and Boulder. Due to the Big Dry Creek stream bank restoration project, there will be periodic closures through fall 2024, and a section will remain closed through summer 2025, with detours available.

If you're a bird enthusiast, the Bald Eagle Viewing Hide is a must-see. It's in a quiet spot with an elevated view, so spotting eagles is way easier. The best times to go are early mornings or late afternoons when the eagles are more active. Don’t forget your binoculars and camera!
