Crater of Diamonds State Park Travel Guide — Arkansas

As the Visit America editorial team, we’re here to cut through the noise and deliver the essential guide to one of the most unique geological wonders in the United States. This isn't just another state park; it's the world's only diamond-producing site open to the public, offering an unparalleled opportunity to unearth your own treasure. We've explored the 37.5-acre plowed field, sifted through countless buckets of soil, and gathered all the crucial details to ensure your visit is as sparkling as a freshly found gem. From practical tips on finding diamonds to the best places to stay, consider this your definitive resource for exploring this remarkable Arkansas destination.

Why Visit Crater of Diamonds State Park

The allure of Crater of Diamonds State Park is undeniable: it’s the only place in the world where the public can search for real diamonds in their original volcanic source and keep whatever they find. This isn't a staged attraction; it's a genuine, active diamond field, the eroded surface of an ancient lamproite volcanic pipe that brought diamonds to the earth's surface millions of years ago. Since becoming an Arkansas state park in 1972, visitors have unearthed over 37,377 diamonds, with an average of one to two diamonds found per day among all visitors. Beyond the sheer thrill of discovery, the park offers a fascinating glimpse into geology and history. Imagine walking the same ground where the 40.23-carat "Uncle Sam" diamond, the largest ever found in the U.S., was discovered, or the 16.37-carat "Amarillo Starlight". We find the blend of outdoor adventure, the possibility of striking it rich, and the educational opportunities truly compelling. It’s a hands-on experience that captivates both seasoned rockhounds and curious first-time visitors, making it a bucket-list stop for any Arkansas adventure.

Who It's Best For

Crater of Diamonds State Park truly offers something for everyone, making it a fantastic destination for a diverse range of travelers. It's unequivocally best for families with children, who will delight in the hands-on activity of digging for treasure. The "finders keepers" policy sparks a unique excitement in kids (and adults!) that few other attractions can match. Educational groups and science enthusiasts will appreciate the geological significance of the site and the interpretive programs offered at the Diamond Discovery Center, which explain the volcanic history and diamond formation.

Avid rockhounds and amateur prospectors will find themselves in a paradise, with the chance to find not only diamonds but also other semi-precious gems and minerals like amethyst, agate, jasper, and quartz. The park's unique environment provides a rewarding challenge for those keen on the hunt. Even if you don't find a diamond, the satisfaction of sifting through the earth and identifying other interesting rocks is a fulfilling experience. Finally, outdoor enthusiasts looking for a unique adventure will appreciate the opportunity to spend a day outdoors, whether digging, wet sifting, or simply surface searching in the 37.5-acre field. It’s a place where patience and a keen eye can truly pay off, creating unforgettable memories for all.

Getting There & Parking

Reaching Crater of Diamonds State Park, located in Murfreesboro, Arkansas, is a straightforward journey, though it takes you into a charmingly rural part of the state. From Little Rock, the state capital, we recommend taking I-30 West to Exit 73, then following AR-26 West directly to the park. The park's roads are well-maintained and are even big rig-friendly for those traveling in larger RVs. Murfreesboro itself is about 2.5 hours from Little Rock, making it an accessible day trip or a perfect anchor for a longer Arkansas exploration.

Once you arrive at Crater of Diamonds State Park, you'll find ample parking available. There is dedicated RV parking conveniently located near the diamond field and the visitor center. During the summer months, additional parking spaces are available at the Diamond Springs Water Park. We've noted an estimated day-use parking capacity of 300 vehicles, which generally accommodates visitors well. It's important to remember that once you park, the best and only way to get around the park's main attractions, including the diamond search area, is on foot. So, wear comfortable shoes, grab your gear, and prepare to explore!

Top Things to Do

While the primary draw of Crater of Diamonds State Park is, without a doubt, the diamond search area, our team has found that there are many more things to do at Crater of Diamonds State Park to round out your visit and make it a truly memorable experience. Here's our curated list:

• Dig for Diamonds: This is the main event! Spend hours in the 37.5-acre plowed field, sifting through volcanic soil in search of white, brown, and yellow diamonds, as well as other gemstones like amethyst, garnet, jasper, and agate. The "finders keepers" policy means everything you unearth is yours to take home. We highly recommend visiting 2-3 days after rainfall, as the rain washes away lighter soil and exposes heavier diamonds near the surface.
• Learn at the Diamond Discovery Center: Before heading out to the field, stop by the Diamond Discovery Center. Here, you can learn about the park's unique geology, the history of diamond finds, and the best techniques for searching. Park staff offer free identification and certification of any diamonds you find, and can help identify other rocks and minerals too. You can also rent all the necessary equipment here, from shovels and buckets to screen sets and sarucas.
• Cool Off at Diamond Springs Water Park: During the warmer months, especially from Memorial Day to Labor Day, Diamond Springs Water Park offers a fantastic way to beat the Arkansas heat. This mining-themed water play area features a wading pool, spray geysers, water slides, and waterfall hideaways, providing a refreshing break for families after a day of digging. Note that it's seasonal and typically closed on Mondays and Tuesdays, with potential weekend-only operations in mid-August.
• Explore the Hiking Trails: While not the primary focus, Crater of Diamonds State Park offers pleasant walking trails that allow you to appreciate the natural beauty surrounding the diamond field. These trails provide a different perspective of the park's landscape and are a great way to stretch your legs.
• Enjoy a Picnic: The park features numerous picnic sites, perfect for enjoying a packed lunch amidst the scenic surroundings. It's a great way to refuel and relax before heading back to the search area.
• Visit the Gift Shop: Commemorate your visit with a souvenir from the park's gift shop, offering a range of diamond-themed items, geological specimens, and other mementos.

These things to do at Crater of Diamonds State Park ensure a well-rounded and engaging visit, whether you strike it rich or simply enjoy the unique experience.

Best Time to Visit

Our team has found that timing your visit to Crater of Diamonds State Park can significantly enhance your experience, both in terms of comfort and your chances of finding a diamond. Generally, the best conditions for finding diamonds are 2-3 days after rainfall, as the rain washes away lighter soil and exposes diamonds closer to the surface.

Considering the weather, spring (March-May) and fall (September-November) offer the ideal balance of pleasant temperatures, moderate crowds, and good chances of rain, which aids in diamond exposure. Spring brings ideal weather and frequent rain, while fall provides cool temperatures and fewer visitors.

Summer (June-August) can be hot and crowded, with temperatures often reaching over 110 degrees F in the search area. If you visit during summer, we strongly recommend arriving early in the morning to beat the heat and the largest crowds. The Diamond Springs Water Park, open seasonally from Memorial Day to Labor Day, is a welcome respite during these hotter months.

Winter (December-February) is the coldest and least crowded season, though there might be less rain, which can impact diamond finding conditions. Regardless of the season, we advise wearing old clothes and shoes you don't mind getting dirty, and bringing plenty of water and sun protection, as the diamond search area is an open field with limited shade.

Where to Stay Nearby

While Crater of Diamonds State Park offers excellent on-site camping, our team recognizes that not every traveler prefers roughing it. Fortunately, the charming town of Murfreesboro and the surrounding area provide a variety of lodging options to suit different preferences and budgets, ensuring a comfortable stay after a day of digging.

For those who wish to maximize their time at the park, staying within the park's campground is an excellent choice. The Crater of Diamonds State Park camping facilities are well-regarded, featuring 47 Class AAA campsites with full water, electric, and sewer hookups, capable of accommodating RVs up to 60 feet. Each site includes a paved RV pad, picnic table, fire ring, and lantern post. Additionally, there are five walk-in tent sites for a more traditional camping experience. The campground is tree-shaded, providing natural cooling, and includes two modern bathhouses with hot showers, along with a coin-operated laundry facility available from March to November. Pets are welcome in all campsites. Reservations are highly recommended, especially during peak seasons, and can be made through the Arkansas State Parks website.

In Murfreesboro itself, you'll find cozy inns and motels. The Queen of Diamonds Inn, for example, offers Victorian charm with modern comforts just minutes from Crater of Diamonds State Park. For those looking for lakeside access and a bit more tranquility, Swaha Lodge and Marina on Lake Greeson provides a scenic retreat.

Beyond Murfreesboro, travelers can consider a slightly longer drive to nearby towns for more options. Hot Springs, home to Hot Springs National Park, is about an hour and a half away and offers a wider array of hotels, resorts, and dining experiences. For a truly unique Arkansas experience, consider venturing further north to explore the Eureka Springs Historic District, though this would be a multi-hour drive and best suited for a separate leg of your trip.

Whether you opt for the immersive experience of Crater of Diamonds State Park camping or prefer the comforts of a local inn, you'll find a welcoming base for your diamond-hunting adventure.
