You’re standing in a 37-acre plowed field in Murfreesboro, Arkansas, staring at the dirt. It’s hot. Your back aches. Every shiny bit of quartz or jasper looks like a payday, but deep down, you know it’s probably just a rock. This is the only place on the planet where the public can hunt for real diamonds at their original volcanic source and actually keep what they find. But here’s the thing: most people treat the Crater of Diamonds State Park campground as just a place to park their rig or pitch a tent while they hunt for treasure.
That's a mistake.
If you don’t play your cards right with the logistics of this specific park, you’ll spend more time fighting for a spot or trekking back and forth to your site than actually finding anything worth keeping. Most visitors think they can just roll in on a Friday and find a spot. Nope. Not even close.
Why the Crater of Diamonds State Park Campground Is Actually the Secret to Finding More
The campground isn't just a convenience; it’s a tactical advantage. There are 47 AAA-rated campsites here. When we say "AAA," we aren't talking about a roadside assistance club. In the Arkansas State Park system, AAA means you're getting the full works: water, sewer, and both 30-amp and 50-amp electrical hookups.
Staying on-site matters because diamond hunting is exhausting work. Honestly, it’s brutal. You are essentially doing manual labor in a field that has been turned over by a tractor. If you stay at a hotel in town or a private park twenty miles away, you lose the "golden hour" of searching.
Ever wonder why some people seem to find diamonds every time they visit? They’re usually the ones who are on the field the second it opens. Staying at the Crater of Diamonds State Park campground puts you a short walk or a very quick drive from the Diamond Discovery Center. You can beat the heat. You can be the first one to scan the ground after a heavy rain has washed away the dust and left the diamonds sitting right on the surface.
Let’s Talk About the Sites
The layout isn't a perfect circle. It’s a bit of a winding loop, heavily shaded by tall pines and hardwoods. This is a massive relief. After spending six hours in the unshaded "crater"—which is actually the eroded surface of an ancient volcanic pipe—returning to a shaded campsite feels like finding a diamond itself.

Most of the sites are back-in. If you’re pulling a massive 40-foot fifth wheel, you’ll need to pay attention to the pad lengths listed on the reservation site. Pad 22, for example, is a decent size, but some of the others can be a bit tight if you have a long tow vehicle. The pads are paved, which is a blessing. Nobody wants to level a camper in Arkansas mud after a thunderstorm.
There’s also a tent area. It’s separate, with five walk-in sites. These are way more "woodsy" and give you a bit more privacy than the RV loop, where you're basically neighbors with everyone else.
The Reality of Booking (It’s Stressful)
You can’t just wing it. If you’re planning to visit during Spring Break or any long weekend, you need to book months in advance. The Arkansas State Parks reservation system is straightforward, but the demand for this specific park is through the roof.
I’ve seen people show up at the visitor center hoping for a cancellation. It happens, but rarely. If you miss out on the Crater of Diamonds State Park campground, your next best bet is usually Lake Greeson, specifically the Swaha Lodge or the COE (Corps of Engineers) parks nearby. But then you’re driving. And driving means less digging.
How the Weather Changes Everything
Arkansas weather is moody. In the summer, the humidity feels like a wet blanket. In the winter, it’s surprisingly mild but can get "bone-chilling" damp.
The best time to be at the campground? Right after a big rain.

Diamonds are adamantine. That’s a fancy way of saying they have a super high luster. They don't stick to dirt; the dirt washes off them. When the sun comes out after a rainstorm, the diamonds "pop." If you're staying at the campground, you can watch the radar, wait for the clouds to break, and hit the field while everyone else is still driving in from Nashville or Texarkana.
Diamond Hunting 101 for Campers
You’ll see people with elaborate setups. Giant screens, custom-built sluice boxes, and specialized shovels. You don't need all that. You can rent the basics—a bucket, a shovel, and a "saruca" (a circular screen)—right at the park.
Most people use the "dry flicking" method. You sit on the ground, move a little dirt, and look for a flash. But the pros? They wet-sift. They take buckets of dirt to the washing stations, use a series of screens to sort the gravel by size, and then flip the screens over onto a table. Because diamonds are heavy, they settle in the center of the screen.
When you’re staying at the Crater of Diamonds State Park campground, you have the luxury of taking your "concentrate" (the heavy gravel left after sifting) back to your campsite. You can sit at your picnic table under the shade, drink a cold soda, and pick through your gravel in peace. It’s way better than hunching over a dirty table at the wash station while twenty people stare at you.
What You’re Actually Looking For
Don't look for "jewelry store" diamonds. Most diamonds found here are small—about the size of a matchhead. They look like rounded bits of glass or oily pebbles. They come in three colors: white, brown, and yellow.
The famous "Strawn-Wagner" diamond, a 3.03-carat gem found in 1990, was eventually cut into a perfect 1.09-carat stone. It’s the highest quality diamond the American Gem Society has ever graded. That could be in the dirt right next to your tent. Seriously.

Beyond the Diamonds
The park isn't a one-trick pony. If you get skunked at the mine, there’s the Little Missouri River nearby. It’s great for fishing. There’s also a water park on-site called Diamond Springs. It’s basically a massive splash pad with slides, and if you have kids, it is the only thing that will save your sanity after they get bored of digging in the dirt.
The campground also has a very solid bathhouse. It’s clean. It’s heated. It has hot showers. When you’ve spent the day covered in the unique "lamproite" soil of the diamond field, a hot shower is non-negotiable. That soil is weirdly greasy and clings to everything.
Misconceptions About the Park
People think the park "seeds" the diamonds. They don't. These are 100% natural. The park staff just plows the field every month or so to bring new dirt to the surface. It’s a genuine geological anomaly.
Another misconception is that the Crater of Diamonds State Park campground is loud. Usually, it’s the opposite. People are so tired from digging all day that the park goes quiet pretty early. It’s a family-oriented vibe. You’ll see kids riding bikes and plenty of people Comparing their "finds" (mostly jasper and quartz) around campfires.
Essential Gear for Your Campsite
- A wagon: Not for your kids, but for your gear. Dragging two 5-gallon buckets of wet dirt across a field is no joke.
- Extra shoes: You will get muddy. The kind of mud that ruins carpets. Leave your "mine shoes" outside the camper.
- A 10x magnification loupe: Don't guess. If you find something shiny, look at it under a lens. If it has smooth, rounded edges and looks like it’s coated in vegetable oil, get it to the Discovery Center.
- Sun protection: The field has zero trees. None. It’s an oven.
Navigating the Murfreesboro Area
Murfreesboro is a small town. It lives and breathes diamonds. There are a few local spots to eat, like Hawkins Variety (it’s a classic soda fountain) or the various pizza and Mexican spots around the square.
But honestly, the best part of staying at the Crater of Diamonds State Park campground is the campfire cooking. There’s a grocery store in town (Cash Saver) where you can grab steaks and charcoal.
Actionable Steps for Your Diamond Trip
If you want to actually enjoy this trip instead of coming home sunburnt and empty-handed, follow this exact sequence:
- Book the site 6 months out. Use the official Arkansas State Parks website. Don't rely on third-party aggregators.
- Check the Plowing Schedule. Call the park office. They don't have a rigid "first Tuesday" schedule, but they can tell you when the field was last turned over. You want to be there shortly after a fresh plow or a heavy rain.
- Rent the "Diamond Mining Kit." It’s cheaper than buying your own gear and you don't have to haul it home. It includes the screens and a bucket.
- Go to the Discovery Center First. Look at the raw diamonds in the display cases. Your brain needs to know what a "raw" diamond looks like (hint: it doesn't look like a ring).
- Focus on the low spots. After a rain, diamonds wash down into the gullies and "natural riffles" in the field. Don't just dig a random hole; look where the water has already done the work for you.
- Take advantage of the free ID. The park staff will identify your rocks for free. Don't leave thinking you found a piece of glass; let them check it. You might be surprised.
The Crater of Diamonds State Park campground is one of the most unique camping experiences in the United States. It’s not just about the "get rich quick" dream. It’s about the weird reality of sleeping on top of an ancient volcano and spending your morning looking for something that hasn't seen the light of day for 100 million years. Even if you only leave with a pocket full of "fool’s gold" and some pretty jasper, the experience of the hunt is worth the effort. Just remember to bring a sturdy pair of boots and a lot of patience.
