Flat, easy trails make a leisurely stroll around the park a comfortable experience. There are more than 7 miles of interconnected trails, some specific routes are as follows:
Pelican Pond Trail is 1.3 miles and follows the shoreline of Pelican Pond, overlooks St. Vrain Creek, and crosses a footbridge to Mallard Pond. It can also be accessed from Blue Heron Reservoir Parking, which adds 0.4 miles round-trip. The Weld County Legacy Trail connects with this trail from below I-25 along the creekside. This section from I-25 all the way to the park entrance is paved in concrete.
Muskrat Run Trail is a 1 mile loop that connects Sandpiper, Avocet, Killdeer, and Mallard Ponds.
Bald Eagle Pond Trail is a 1 mile loop that encircles Bald Eagle Pond and connects to Coot Pond.
Coot Pond Trail is a 0.6 mile loop that connects to trails on Bald Eagle and Pintail Ponds.
Red Tail Pond Loop is a short 0.35 mile loop for shoreline access at Red Tail Pond. This trail is not as accessible as the others because of steeper grades, narrow trails, and erosion/sink holes.
Blue Heron Reservoir Trail is a 1.6 mile loop that provides shoreline access to Blue Heron Reservoir.*
* This trail joins with another 0.6 mile section of trail that crosses County Road 7 westbound onto the LaFarge property at St. Vrain. This section of trail is part of the Colorado Front Range Trail at St. Vrain and will eventually connect to the City of Longmont trail system from Sandstone Ranch; however, until that time the trail is a dead end. No access is permitted on any other portion of the LaFarge property at this time and is signed and fenced as such. This area is very good for wildlife viewing, especially for birding, including a close look into a Great Blue Heron rookery that was once the largest in the state.
