Missouri state-park sites open a full 12 months out — and the lake parks force a 2-night weekend minimum
Since June 2020, Missouri State Parks take reservations a full 12 months in advance (the window opens 7am CST, bookable up to 7pm CST the day before arrival) through icampmo.com or 877-422-6766. Eight of the highest-demand parks — Big Lake, Lake of the Ozarks, St. Joe, Table Rock, Mark Twain, Wakonda, Wallace and Watkins Mill — require a 2-night minimum on weekend reservations (Fri/Sat or Sat/Sun). Camping is also capped at 15 days within any 30-consecutive-day period at one park, so set a 12-month alarm and don't plan a single Saturday night at the lakes.
