Are you looking for caves in Iowa? You are in the right place.
In this article, I have picked the best of the Iowa caves and given you all the information you need so you make a decision on which is the best cave for you to visit.
I have to say when I think of Iowa the first thing that springs to my mind is not caves. However, Iowa has some really interesting and somewhat magical caves and cave systems.
From deep caves full of stalagmites, caves that have rivers running through them, and caves with ice in them all year round, some are so majestic they wouldn’t be out of place in an epic movie.
With over 1000 caves Iowa really does have it all when it comes to underground exploring. Stepping into them is like stepping into another world.
When it comes to caves in Iowa there really is a cave for everyone.
One thing I will advise is that if you go exploring take a jacket or sweater these caves can get cold. Caves in Iowa are a constant 45 to 55 degrees.
Also, make sure you wear sturdy shoes suited for these environments as the inside of caves can get slippery.
In this list, I have included the caves that are open to the public and safe to explore. They all offer something a little bit different so I’m sure you will be able to find the right cave to visit.
So let’s put on our sturdy shoes, get out our flashlight and go exploring.
10 Amazing Caves In Iowa For You To Explore
Maquoketa Caves In Maquoketa Caves State Park
If you like your caves big and majestic with a side of awe then Maquoketa Caves Iowa will be for you.
Set in the unique Maquoketa Caves State Park there are 13 caves for you to explore here.
From the magnificent 1,100-foot Dancehall Cave which is the longest public, wild cave in Iowa to smaller ones you might need to crawl in.
Dancehall Cave is easy to explore as lights and passageways are set up and established.
However, if you want to explore some of the smaller caves like Bat Passage and Dugout Cave you might want to bring a flashlight.
The caves are all linked by a trail system so It’s easy to get around.
There are four types of caves here solutional, mechanical, talus, and rock shelters. All offer something different.
These caves were used by Native Americas and later became a popular picnicking spot for settlers, some of who stole the white stalactites.
Also definitely worth seeing is Natural Bridge and Balanced Rock which you can explore on the 6 miles of trails within the park.
Maquoketa Caves State Park Iowa is a natural experience unlike anything else. Hiking in Iowa is popular here. However, the Iowa trails can get wet and muddy, so be prepared.
The state part also has a campground if you fancy spending a few days exploring but other than toilets it is pretty primitive so make sure you bring all you need.
Oh the best part is these caves in Iowa are free to enter.
Decorah Ice Cave In Barbara Barnhard VanPeenen Memorial Park
If you want to see something unusual, how about ice in a cave in summer? Decorah Ice Cave is the largest ice cave in the midwest and is really quite spectacular to see.
When it comes to Iowa caves this one is unique. And it is located in one of the cutest small towns in Iowa.
The ice is formed in the winter by water trickling down the cold rock walls forming a layer of ice on the walls.
It begins to form in January/February and remains typically until August. The ice of the walls can be 8-10 inches thick and creates a white crust on the rock.
It’s easy to get to and just a series of quite steep steps and it can get very slippery. You really do need the right footwear here.
The cave is within the Barbara Barnhard VanPeenen Memorial Park which is a great place to visit. As well as the ice cave you will find a freshwater spring, 8 acres of tall prairie grass, and lots of hiking trails.
Entry to the park and cave is free, making this one of the premier locations to see caves in Iowa and the perfect Midwest weekend getaway!
Cave At Backbone State Park
If you are looking to go cave exploring while also doing some other outdoor activities this cave might be the one for you.
Set in Iowa’s first state park, Backbone State Park, is one of the most geographically unique locations in Iowa.
You will find caves, sinkholes, karsts, and active natural springs. You will find 2001 acres to explore.
The park is named after the steep bedrock ridge carved by the Maquoketa River that looks like a backbone,
Or more importantly, The Devil’s Backbone which is what it is referred to. It towers 80 feet over the ground below and the views from the top are spectacular.
The park has 21 miles of trail systems and really does have a hiking option to suit everyone.
The cave is low, four feet, and can get muddy but it makes a cool respite from the summer sun.
As you get further in you will find a stump of stalagmite, an hourglass-shaped column, and a flowstone-covered wall.
The cave is then a belly crawl if that’s your thing or you can just hang here for a while. If you don’t like tight spaces this is not the cave for you.
Again entry to the park and cave are free of charge.
Ice Cave And Horse Thief Cave At Wapsipinicon State Parks
One of the oldest state parks in the state Wapsipinicon offers up a couple of caves to explore, an ice cave, and a bowl-shaped cave known as Horse Thief Cave.
The park is 394 acres so there is much more to see and do here than exploring caves but I will focus on the Iowa caves here.
Horse Thief Cave really is a must-see. Legend has it that two horse thieves used this cave for their camp.
The cave is easy to get to and you can explore a few tunnels inside but you might need a flashlight to do that.
The entrance to the ice cave is up a few steps and is a bit of a squeeze.
It’s a small tunnel-like cave and while there is enough room to walk it is tight and you will need a flashlight.
The park’s caves can be accessed via a well-developed, multi-use trail system

Packing List For Visiting Caves in Iowa
A concealed travel pouch may be one of the most important items you bring along when on your vacations in the Midwest. It is always important to protect your personal information.
Read my tips on how to pack lightly here if you need packing tips.
This unisex RFID blocking concealed travel pouch is lightweight and comes in several colors. It has lots of organization to give you peace of mind.
If you have a pouch already that does not come with the RFID protection, as I do, these RFID sleeves are the perfect solution.
This configuration comes with enough passport and credit card sleeves that the entire family would be protected. They are slim too, so they will easily fit into your pouch or wallet.

I cannot believe how much they really do help with the organization. If you have not considered packing cubes, I would recommend giving them a try.
Hydration is so important. You want to remain hydrated to support your immune system which in turn will be stronger to fight off any germs you will encounter during your travels.
You will want to bring your own refillable water bottle with you.
I never leave home on a trip without my Bobble filtration bottle. The 18.5-ounce size is perfect for travel and it fits nicely in the pocket of a backpack or your purse.

Perhaps you need a more substantial backpack for your travel. This antitheft backpack has a charging port, is water-resistant, and can comfortably carry up to a 15.6″ laptop.
You will be walking more than usual during your weekend getaways in Ohio. A sturdy and comfortable pair of walking shoes are a must-have. These waterproof all-season shoes are extremely affordable and yet fashionable.
Mostly everyone is familiar with the Skechers brand, and these Air Run high fashion sneakers come in a lot of colors to match your outfits and are still affordable.
