St. Vrain State Park
Colorado Parks and Wildlife’s pond-dotted park just west of I-25 at Exit 240, a few minutes from Frederick: 689 acres of land and 228 of water, 87 campsites, seven miles of trail, fishing and bald eagles in winter. A daily vehicle pass is $10 to $12 for Colorado plates.
St. Vrain State Park sits on the north-west edge of Firestone where St. Vrain and Boulder creeks meet, open daily from 5 am to 10 pm with the entrance station staffed 9 to 5. CPW’s page counts 689 acres of land and 228 of water, 87 campsites, 20 picnic sites and seven miles of trail around a string of ponds, with a boat ramp at Blue Heron Reservoir (inspections mandatory) and stocked fishing ponds. A daily vehicle pass is $10 to $12 for a Colorado-plated car ($15 to $17 for out-of-state plates) and an individual pass $4. Leashed dogs and horses are allowed.
Read on 2 November 2026: the south campground road is closed and full-hookup sites 42 to 87 are unavailable; trails on the south and east sides of Bald Eagle and Coot ponds, and all of Red Tail Pond, are closed through November and possibly into December. Entry is free on November 11 for veterans and active military and on November 27, Fresh Air Friday, for everyone.
