The 18 Best Places To Find Ohio Geodes in 2023

By Dr. Keith Jackson - Geology PhD


Geodes are some of the world’s most amazing wonders, but they’re also some of the most challenging ones to find. In Ohio, in particular, they’re are not exactly common sight. But if you’re planning to discover your own geodes here, fret not because we did the hard work and know all the places where you can find them.

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
  • Celestite geodes
  • Dolomite geodes
  • Fluorite geodes
How We Found The Best Geode Locations in Ohio
When it comes to choosing the best options for finding Ohio geodes there are plenty of things we consider. Many of the best locations are closely guarded secrets which can make it really difficult for more casual geode hunters to find success. The key factors in our recommendations are:

  • The deep experience and understanding of our team about the area
  • Recommendations from local groups and clubs
  • How easy it is to get the a particular location
  • Safety and potential hazards when collecting
  • Weighing private and public locations
  • The ability for both experienced and novice geode enthusiasts to find great samples

With these factors in mind we’ve been able to put together a fantastic list that just about anyone can use!

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!

Always Confirm Access and Collection Rules!

Before heading out to any of the locations on our list you need to confirm access requirements and collection rules for both public and private locations.

These requirements are subject to change without notice and may differ from what we state below.

Always get updated information directly from the source ahead of time to ensure responsible rockhounding.

Crystal Cave

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.

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.

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

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.

Common Geode-Hunting Questions

When others search about geode in Ohio online, they often follow it up with other specific questions. We figured you might have these questions, too, and so we’ll tackle them here:

Where can you find amethyst geodes in Ohio?

Amethyst geodes are lovely treasures, but they are quite difficult to find. Unfortunately, this kind of geode does not naturally occur in Ohio. If you’re really looking for one here, you might want to check out a great local rock and gem shop (we have a list of them below).

Is it illegal to collect geodes in Ohio?

If you are following the local collecting laws of our state, you would have no problem, legally speaking, collecting geodes in Ohio. Just make sure that, if you’re collecting on government land, you’ll stick to local regulations and that, if you’re collecting from any private land, you’ll seek permission from the owner first.
