Croke Reservoir

Croke Reservoir is a small urban lake tucked into a residential neighborhood in Northglenn, Adams County, offering a surprisingly pleasant escape for fishing, walking, and wildlife viewing just minutes from the Denver metro area. With a 0.7-mile trail circling the water, a fishing pier, and a scenic wildlife viewing platform, this city park punches above its weight for a neighborhood lake.

Fishing is the primary draw at Croke Reservoir. Bluegill are plentiful and easy to catch, making this a solid spot for beginners and kids learning to fish. Several reviewers also report surprisingly good-sized largemouth bass in the water. The fishing pier has five benches, though only two offer good casting positions, so competition for prime spots is real. Dedicated anglers arrive well before dawn to claim the best seats. One visitor reported catching five fish between 5:30 and 7:00 AM with a child, so early mornings are productive. Access from the Huron Street side is also possible but lacks railings, making it a concern for families with small children.

The paved loop trail around the reservoir makes for a pleasant walk in any season. Reviewers describe it as a wide gravel path with good shade from mature trees, and the fall colors are a particular highlight. The trail can become overgrown in certain sections during warmer months, which may bother visitors with allergies. A picnic pavilion and playground round out the amenities for families.

Wildlife viewing is a genuine bonus at Croke Reservoir. Visitors report diverse bird species making the lake their home, along with various insects and amphibians. The dedicated wildlife viewing platform gives you a good vantage point. The park has sentimental value for many longtime Northglenn residents who grew up climbing its trees and fishing its waters.

Be aware of a few restrictions and considerations before visiting. Dogs and bicycles are not permitted in the park, which has frustrated some visitors who biked over with pets. There is no dedicated parking lot, so you will need to find street parking along nearby residential streets such as Naiad Street. The bridge at the midway point provides lake access. Some reviewers have noted litter and occasional homeless encampments in the area, so conditions can vary.
