The Muskrat Run Nature Trail, within the St. Vrain State Park circles Sandpiper Pond and is about one mile in length. Here you will find picnic shelters on the north side of Sandpiper Pond, while the cattails and tall reeds rustle in the wind along the east.
The trail also connects to smaller honey holes at Killdeer and Avocet Pond, before running along Mallard Pond and the Camper Services Building.
