How to Book Missouri State Parks: Cancellations, Release Times and Alerts
How Missouri State Parks works
Missouri State Parks (icampmo1.usedirect.com) is Missouri Department of Natural Resources, Division of State Parks's booking system for campgrounds. This page is PermitSnag's guide to booking on it, not the booking system itself; you'll reserve directly on icampmo1.usedirect.com.
When cancellations show up
Missouri State Parks opens its booking window on its own schedule — icampmo1.usedirect.com is the source for the exact date. What's constant is what happens after: sites fill, plans change, and cancellations go back onto the calendar. PermitSnag watches campgrounds here and texts or emails you the moment one opens up.
How a PermitSnag watch helps
A PermitSnag watch checks Missouri State Parks on your behalf and texts or emails you the moment a cancellation lands, so you are not the one refreshing the page. Set a watch on any permit or campground you can reach from the links below, or search for it from the full permit directory.
