Although the state recognizes this annual holiday Aug. 1, state parks celebrate the occasion with free entrance on the first Monday of August.
Colorado Day was created by the state Legislature to mark the anniversary of statehood, granted in 1876 by President Ulysses S. Grant.
All other park fees, including camping reservations and fishing licenses, remain in effect.
