Parking at Castle Rock State Park

The main Castle Rock parking lot at 15000 Skyline Boulevard (Highway 35) has been filling to capacity on weekends and holidays. In order to get a place to park and avoid a parking citation, please follow this advise:

  • Arrive Early - The earlier you arrive the better chance you have to find parking. Castle Rock State Park is open for day use from 6am to Sunset. Remember that all vehicles will need to pay an $8.00 parking fee so bring exact change to self-register in case you arrive before the entrance station opens.
  • Come on a Weekday - Avoid the crowds and come during the week.
  • Car Pool - Fewer cars your group brings, the more space we save for other parks users. Plus, its better for the planet!
  • Park in an Alterative Parking Area - There are a number of parking areas along Highway 9 south of Skyline Boulevard (Highway 35). These parking areas give access to the same great system of trails and are FREE to use. Check out the Park Map for locations of other parking areas.
  • Take a Good Look for No Parking Signs - No parking signs are posted along Skyline Boulevard (Highway 35) to restrict parking in areas which impact or endanger others along the highway. Please look for no parking signs and do not park in restricted areas. Rangers and Highway Patrol Officers issue citations.     
  • Do Not Park in the Roadway - If you park along the highways, make sure ALL of your vehicle including side view mirrors are all the way out of the roadway to the right of the white line at the road edge.  

By keeping in mind these tips, you should be able to avoid a parking citation and find a place to park and enjoy Castle Rock State Park.

Visiting Castle Rock

Castle Rock State Park ViewCastle Rock State Park is a land of sculpted sandstone, lush forests, and sweeping vistas.
