Formerly named Barbour Ponds, St. Vrain State Park features 604 acres of land and 152 acres of water, split between several ponds.
It’s easy to reach in Firestone, located between Denver and Fort Collins on Highway I-25. The park features year-round recreation and stunning views of Longs Peak. It’s also home to great fishing and simple boating on the Blue Heron Reservoir.
Camping and other recreation are available year-round. There are miles of trails open to hikers and bikers around the park. Each is a relatively simple trek and perfect for an afternoon or morning excursion.
