Best time to visit Crater of Diamonds State Park
Spring (March through May) and fall (September through October) are the most comfortable months, with mild temperatures ideal for hours spent digging in the search field. Summer brings hot, humid days and frequent afternoon thunderstorms, though the seasonal water park and heavy rainfall that washes up new diamonds draw many visitors. Winter is quieter with cool, damp conditions, and serious diamond hunters often prefer it because rain exposes fresh stones on the plowed surface. Shoulder seasons offer the best balance of weather, campground availability, and search conditions for RV travelers.

Things to do at Crater of Diamonds State Park
- Search the Diamond Field EasyRV parking available
The 37.5-acre plowed search field is the park's main attraction and the only public diamond mine in the world where visitors keep what they find. Diamonds turn up in white, yellow, and brown, alongside amethyst, jasper, and quartz. The field is periodically plowed to bring new material to the surface.
- Diamond Discovery Center EasyRV parking available
The Diamond Discovery Center offers exhibits on the park's geology and free identification of any rocks or minerals visitors find. Staff can verify diamonds and register finds on the spot. It is a practical first stop for newcomers before heading into the field.
- Prospector Trail EasyRV parking available
The Prospector Trail is a short interpretive path near the search area that covers the park's mining history. Signs explain the geology of the lamproite pipe that formed the deposit. It is a flat, family-friendly walk.
- Little Missouri River Trail ModerateRV parking available
This trail follows the Little Missouri River along the edge of the park through hardwood forest. It offers birdwatching, shaded picnic spots, and a break from the open search field. Expect some roots and uneven footing.
- Diamond Springs Water Park EasyRV parking available
Diamond Springs is a seasonal water play area with a splash pad and small pools, typically open during summer. It is a welcome cool-down after hot hours in the search field. Hours are limited outside peak season.
- Visitor Center and Gift Shop EasyRV parking available
The visitor center introduces the park with geology exhibits, a short film, and rental equipment for diamond hunting. Shovels, buckets, and sifting screens can be rented on-site. It is the best place to start a first visit.
