Funded by a dedicated, voter-approved 1/10-of-1% Parks, Soils and Water Sales Tax, which is why Missouri needs no entrance-fee/library-pass system. Only camping and certain facility rentals carry separate fees, booked via mostateparks.com.
Missouri is one of 10 states where the question is moot — parks are free to enter, which beats any pass program. Crossing a border? Arkansas, Illinois, Kentucky, North Carolina work the same way.
Free day-use entry means the gate: walking in, picnicking, trails and swim areas where they exist. It does not make the paid extras free — camping, cabins, shelters and boat launches are booked and paid separately, and specialty sites can carry their own fees (free day-use entry statewide; camping/rental fees vary by site.). The practical upshot for Missouri residents: a spontaneous day hike costs nothing and needs no planning, which beats even the best borrow-a-pass program.
For comparison, and for Missouri residents crossing state lines: the 20 statewide programs all follow the same shape — the parks agency or state library seeds day-use passes into public-library circulation, a resident checks one out like a book for one to three weeks, and the pass covers gate entry (never camping). California, Colorado and New York are the reference implementations.
There's no program because none is needed: Missouri doesn't charge day-use entry at state parks.
