Whether you’re looking for geodes because you love the thrill of the chase or you’re planning to add it to your wonderful collection, here are the confirmed places you can check out here.
What Are Ohio Geodes?
Geodes are spherical rocks formed by mineral deposits that accumulate over time. These mineral deposits fill a cavity within the rock, creating a hollow center filled with crystals or layers of minerals. The unique geology of Ohio makes the formation of geodes possible!
Here’s a quick and easy guide on how to identify unopened geodes to help you out.
Formed in a variety of locations including volcanic rocks, sedimentary rocks, and igneous rocks, geodes are often sought after by collectors and used for decorative purposes due to their unique appearance and the beautiful crystals inside. What’s more, they can be found in a variety of colors, depending on the minerals present in the area where they were formed. Such fascinating wonders!
The Types Of Geodes Found In Ohio
The world abounds in different kinds of this natural wonder and the price of a geode depends on it. Here in Ohio, below are some of the ones you’ll find:
- Barite geodes
- Calcite geodes

The Best Places To Find Geodes in Ohio
To help you in your search for geodes, we’re sharing with you the confirmed places where you can find them here. While you might already be familiar with the great places to mine gems in Ohio, they don’t necessarily have geodes in them, too. So while the places we will share here may not be well known, they are proven to be the best places to look for geodes here!
Known as the “world’s largest geode,” Crystal Cave is located about 40 feet under the earth’s surface in Put-in-Bay, an island in Lake Erie. Its crystals were formed millions of years ago when the water table was higher and the cave was filled with water. Over time, minerals seeped in and created the crystal formations we see today. It’s like a science experiment gone wild!
If you want to see for yourself this geode, you can ride the ferry from Port Clinton and take a short ride over to Put-in-Bay. From there, it was just a short walk to the cave entrance.
But before you bring any geode home, make sure to check first the updated guidelines from the State of Ohio.
Where we found geodes in Crystal Cave
Crystal Cave is home to the world’s largest geode with gorgeous formations of celestite crystals. This place is so popular, with visitors going over to Ohio with the sole purpose of visiting it. The largest celestite in Crystal Cave is estimated to be 12,000 to 15,000 years old and measures three feet in width.

Other Great Places To Dig For Ohio Geodes
While we’ve already share our favorite places to find geodes here, there are other places you can explore in our state for some geodes adventure. We’ve listed them down below by county to make it easier for you. For places where we put, “county wide”, we’ll prove more specific recommendations in the following item.
Our recommendations by county
|Adams||On the western edge of Serpent Mound|
|Coshocton||The Mohawk Dam spillway, western part|
|Highlands||On the western edge of Serpent Mound|
|Ottawa||Inside the Crystal Cave in Put-in-Bay|

Additional areas you should try
We know “county wide” may be too broad and wide a search for geodes for you, so while we put it in a number of our recommendations above, we’ll narrow them down for you. Here’s some of the places you should visit in those counties for geodes:
Mines and Mine Dumps
If you’re on the hunt for geodes, you have check out old mines and mine dumps. These spots are seriously a mine (pun intended) for geode collectors. They’re often full of all kinds of interesting rocks and minerals, some of them including geodes.
Geodes can form in all kinds of different environments, but one of the most common is in volcanic rocks, which you’ll often find in and around old mines. Another reason these are such great spots to find geodes is because they’re often already full of broken rocks and debris, which means you won’t have to do as much digging to find what you’re looking for.
Streams and Creeks
You can’t go wrong with streams and creeks when it comes to finding geodes. Like natural treasure troves for rock collectors, these bodies of water often run through areas with lots of exposed rock that are constantly being eroded and washed downstream. And sometimes, those rocks and minerals will include geodes.
Streams and creeks are also constantly changing. Water levels can rise and fall, and the movement of the water can uncover new rocks and minerals that were previously hidden. This means that you can often find new treasures each time you visit here.
These places are seriously a hidden gem for geode collectors! Because they’re often dug into areas with interesting rock formations, rocks and minerals including geodes are already exposed and ready to be discovered in quarries.
Another reason why quarries are such great spots for geode hunting is because quarries are usually owned by companies and are off-limits to casual collectors. But if you can get permission to hunt here, you might just be the first person to discover some amazing geodes in years!
Pay-to-Dig Mines are seriously some of the best areas when it comes to finding awesome geodes. They’re often located in areas with rich mineral deposits, so there’s a good chance you’ll find some amazing finds there. And because these mines are specifically set up for rock collecting, you’re more likely to find high-quality specimens than in other locations.
Another reason why pay-to-dig mines are so great is that they often have knowledgeable staff who can help you identify the rocks and minerals you’re finding. This means you can learn a lot about geology and mineralogy while you’re having fun collecting.
