Fees
Colorado State Parks charge camping fees under a statewide flat fee schedule by site type, not park-specific nightly rates: Backcountry $13-$18/night, Basic (no hookup) $22-$28/night, Electric $27-$36/night, Full hook-up (water/sewer/electric) $32-$41/night, Accessible/Group $22-$41/night - plus a separate daily park entrance pass ($10-$11/vehicle) required in addition to camping fees. Individual park pages quote sub-ranges of this same schedule depending on which site types that park offers. (Source: cpw.state.co.us/camping fee schedule.)
