Statewide · Colorado
St. Vrain State Park is a Colorado Parks and Wildlife campground in Firestone, just off I-25 between Denver and Fort Collins. It is the sort of place we route through on purpose: a year-round public park with fishing ponds and a surprising calm given how close the interstate is, and it suits travelers who need a convenient first or last night on the Front Range or a hookup base for exploring the Denver-Boulder-Fort Collins corridor without a resort price tag.

St. Vrain State Park is a Colorado Parks and Wildlife campground in Firestone, just off I-25 between Denver and Fort Collins. It is the sort of place we route through on purpose: a year-round public park with fishing ponds and a surprising calm given how close the interstate is, and it suits travelers who need a convenient first or last night on the Front Range or a hookup base for exploring the Denver-Boulder-Fort Collins corridor without a resort price tag.
The practical picture is unusually good for a state park. Of 87 sites, 46 have full hookups with water, sewer and 30/50-amp electric and 41 are electric-only, all on level concrete pads that take rigs up to 40 feet. Rates in our guide are $36 for electric and $41 for full hookup, plus the CPW vehicle pass. Reservations go through Colorado Parks and Wildlife up to six months ahead, and because it is open year-round it works for winter transits too. The trade-off is setting: this is a plains park beside a freeway, not a mountain campground, so treat it as a comfortable base rather than the destination.
