It’s hard to imagine finding one cave in Iowa, let alone 13 of them! Maquoketa Caves State Park is a lesser-known geological paradise in eastern Iowa. Before you put on your headlamp and start exploring, you may be curious about how the caves formed and how to explore them.

This article will explore each of the 13 caves at Maquoketa Caves State Park in detail, including their formation, the necessary gear for exploration, and the difficulty of navigating through the caves. 

Exploring the Maquoketa Caves will require proper preparation, packing the right gear, and a few miles of hiking. Let’s start exploring!

How The Caves Formed

Let’s start at the beginning and take a trip down memory lane about 400 to 500 million years ago. At this time, the entire state of Iowa sat beneath a tropical sea. As time passed, the sea receded, leaving behind limestone and the various sediment layers that formed on top.

Tectonic plates shuffled around a bit over the next few million years, moving Iowa to its current position today. During that shuffling, cracks formed in the limestone, opening it to erosion by water.

As rain falls, it picks up other chemicals like carbon dioxide to form slightly acidic water. Over many millions of years, this acidic water eroded the limestone at the Maquoketa Caves, forming what you see today. By the way, it takes about 100,000 years for water to erode rock enough to form a cave big enough to fit a human!

Caves can form in many different ways, but this type of dissolution is one of the most common and can be found at famous cave locations like Jewel and Wind Caves in the Black Hills.

Now that we know how the caves were formed, let’s start exploring one of the most unique State Parks in Iowa!

Exploring The 13 Maquoketa Caves

Below, I’ll go over each of the 13 caves that can be found at Maquoketa Caves State Park. The caves will be in order according to the easiest way to explore all 13 in a single hike.

To start things off, we’ll explore the caves located on the northern side of the park. Check out a Maquoketa Caves State Park map to orient yourself around the cave areas and park.

I highly recommend wearing a sturdy pair of hiking shoes or boots and wearing clothes you don’t mind getting muddy. It’s also a great idea to bring a headlamp, as none of the caves are lit except Dancehall.

Here’s the best way to explore all 13 caves in a single hike at Maquoketa Caves State Park:

1. Window Cave

Once you park your car, head to the northern side of the park, across the road from the park store and restrooms. You’ll descend a set of concrete steps and eventually hit a boardwalk. From here, take the dirt trail to the left and follow it to the valley floor. Once you reach the valley floor, Window Cave will be the first cave you pass on the left.

Window Cave corresponds to #6 on the Maquoketa Caves State Park map. This cave has an interesting entrance with jagged rocks. Most will have to stoop to enter the cave, and the roof doesn’t get any higher inside, so watch your head!

Window Cave is short and sweet with an interesting ‘window’ that can only be seen if you’re inside the cave looking out. You’ll see it in the top right corner. Once you exit the cave, take a glance around to see the Natural Bridge, which we’ll be passing under a little later!

2. Match Cave

A little further down the trail from Window Cave is Match Cave, which will also be found on your left and up a set of wooden stairs. It’s a great cave for beginner spelunkers, but some belly crawling is required to explore the entirety of this cave!

A good pair of caving gloves can save your hands from scrapes when exploring a more difficult cave system. These Petzl Cordex Lightweight Belay Gloves allow for maximum dexterity while still protecting your hands from unexpected scrapes.

Match Cave has two passages, the largest of which is around 30 feet long. This isn’t the best cave if you simply want to walk through and see some cool formations. The cave’s roof is so low that you must be on hands and knees to enter, and must crawl most of the way. However, it’s worth a peek at least to see the passages!

3. Wide Mouth Cave

As you continue down the path in Maquoketa Caves State Park, you’ll come to an intersection. Left takes you to the campground, so we will instead take the right path to continue our cave exploration. The trail crosses Raccoon Creek, which feeds into the Maquoketa River, and then begins to head north.

On the way to Wide Mouth Cave, you’ll pass by a few offshoot boardwalk trails, which we will hit on the way back. For now, stick to the path until you come to a boardwalk trail that leads to Wide Mouth Cave.

This cave has a wide opening resembling a half-moon and requires stooping to enter. The cave is not very long and is more of a shelter from the rain. Before souvenir hunters raided this cave, it was filled with pure white stalactites and stalagmites. Unfortunately, none are left to see now.

After checking out Wide Mouth Cave, return to the trail and retrace your steps, heading back to the caves you passed along the way.

4. Dug Out Cave

The first cave you’ll pass on the return journey is Dug Out Cave, which will be located on the left-hand side of the trail. It’s not all that exciting, as it’s just a small sheltered cave with little exploring to be had. If you have to skip one cave in Maquoketa Caves, this would be the one.

5. Twin Arch Cave

Shortly after Dug Out Cave, you’ll return to the boardwalk trail, which hugs the limestone cliff. As you approach the intersection, stay left instead of heading back toward Match Cave. Just after the intersection is Twin Arch Cave.

Twin Arch Cave supports two arches and is worth exploring due to the many fossils that can be seen on its ceiling. These fossils are from shelled sea creatures that once thrived in the tropical sea before these caves were formed! Twin Arch is one of the most interesting formations at Maquoketa Caves.

6. Hernando’s Hideaway Cave

As you return to the boardwalk trail and walk a little further down, you’ll come across Hernando’s Hideaway Cave. To fully explore this cave, you’ll need to do some belly crawling and slithering. 

However, even if you don’t want to fully enter the cave, it’s still worth a stop for the unusual entrance and rock formations.

7. Up-N-Down Cave

The next cave you’ll come across on the boardwalk trail is the Up-N-Down Cave. The entrance is several feet off the ground, making it an enjoyable ingress for spelunkers.

The Up-N-Down cave is a fun traverse at Maquoketa Caves, but it requires belly crawling and is best suited for those with proper gear and knowledge of cave exploration.

8. Dancehall Cave

After Up-N-Down Cave, continue on the path toward Dancehall Cave, the most popular attraction at Maquoketa Caves State Park. Before arriving, you’ll walk underneath the magnificent Natural Bridge. This bridge was formed when a sinkhole gave way, leaving behind the natural arch. This area was likely once the entrance to Dancehall Cave.

When the Natural Bridge is behind you, you’ll see the large opening of the Upper Entrance to Dancehall Cave. Dancehall Cave is the largest cave in the park and the biggest attraction, so expect some company as you explore this geological beauty.

Once inside, there is a short section with a low roof, but afterward, the entire cave has a fairly high ceiling and is wide open. Electric lights are installed throughout the cave, but a flashlight can still be helpful to spot some of the cave formations.

Dancehall Cave travels beneath the parking lot and comes out on the southern side of the park. As you traverse through the cave, you may notice a small entrance on the right wall of the cave. This is Bat Passage and travels for around 75 feet before reconnecting with the main cavern.

As you continue to traverse the cave, you’ll eventually arrive at the Middle Entrance with daylight pouring through the opening and a set of wooden stairs visible. If you look to the right of the stairs, you’ll notice a small entrance. This is Steel Gate Passage, a twisty, curvy 500-foot passage that is considered difficult.

The Middle Entrance was caused by another sinkhole named “Devil’s Cavern” by the locals. Instead of exiting through the Middle Entrance, continue your journey through Dancehall Cave. You’ll pass a large, open area on your right. This is the dance hall, where locals used to come and dance in the cool temperatures of the cave.

Continue on the path until you exit Dancehall Cave via the Lower Entrance. 

9. Rainy Day Cave

As you exit the Lower Entrance to Dancehall Cave, you’ll continue downward on the boardwalk trail and eventually come to Rainy Day Cave, which is marker #15 on the map.

Rainy Day Cave has two rooms. The first is great for exploring, as it’s large and you can easily stand inside. As the name suggests, there is water in this cave in the form of a stream running through the cave.

Follow the stream back to the second room, which is slightly smaller and requires you to stoop. Once you’re done exploring Rainy Day, return to the trail and continue south.

Intermission 1: Fat Man’s Misery & Tall Man’s Misery

Before we explore the next Cave, you’ll pass by two interesting rock formations that are considered caves, but formed in a different way than the rest at Maquoketa Caves State Park.

From Rainy Day Cave, continue south on the trail, following the large rock wall. You’ll start to rise in elevation and come to a ledge that split from the rock face many years ago, creating a mechanical cave. This is Fat Man’s Misery, a narrow cave with stone steps carved in for easy navigation.

Despite the name, it’s fairly easy to navigate through this lean-to-like cave.

After squeezing through Fat Man’s Misery, you’ll encounter Tall Man’s Misery, another small mechanical cave formed by a cataclysmic sliding of rock. You can either duck under or go around (it’s more fun to duck!).

10. Ice Cave

Now, back to our regular cave exploration at Maquoketa Caves State Park. After navigating around Fat Man’s and Tall Man’s Misery, continue on the trail. You’ll encounter a set of stairs that lead to Ice Cave.

Inside, you’ll notice the temperature is much cooler than the other caves, indicating that a cave with actual ice in it is close by. Ice cave consists of two rooms to explore, with the first one being the largest.

11. Shinbone Cave

We’re getting down to the last few caves! As you exit Ice Cave, continue on the path until you see a trail on the right that leads across Raccoon Creek. Once you cross the creek, hang a left at the T-intersection and head up a somewhat strenuous and narrow trail that’s elevated above the stream before arriving at Shinbone Cave.

Shinbone Cave has a large opening and is a favorite roosting place for wrens and eastern phoebes in the summer, thanks to its numerous nooks and crannies. 

If you’re into spelunking, there is a deeper passage behind some rocks and rubble hidden within the cave. Be careful, this cave is called shinbone for a reason!

12. Barbell Cave

To reach Barbell Cave, you’ll have to do some backtracking. From Shinebone Cave, return to the main trail and head back toward where you crossed Raccoon Creek. However, instead of crossing, remain straight on the trail, following it until you reach Barbell Cave, which is marked as #8 on the map.

The trail to Barbell Cave is fairly strenuous, similar to Shinbone Cave.

Barbell Cave has two openings, but the one on the left is not passable. Check out the passage to the right, but note that this cave is best explored by those who don’t mind tight spaces. If you’re willing to withstand the tight fit, you’ll be rewarded with an opening into a second room filled with cave formations. 

Another tight-fitting passage can be found to the right of Barbell Cave.

Intermission 2: Balanced Rock

The final cave on our list is Wye Cave, but before we arrive at our ultimate destination, you’ll pass by yet another interesting rock formation: Balanced Rock.

When you exit Barbell Cave, take the trail back toward the parking lot, heading north. The path will take you right by Balanced Rock, a precariously perched boulder that seems to defy gravity!

Take in this magnificent geological wonder and continue along the trail. You’ll eventually come to a set of stone steps with a sign indicating the way to the Picnic Area, Wye Cave, and the Campground. 

Follow these steps to the stone WPA shelter. Behind the shelter, you’ll find a trail sign marking the way to Wye Cave.

13. Wye Cave

Wye Cave is off on its own and located at a higher elevation than the other caves on our list. The trail starts behind the stone WPA shelter, but can also be accessed from the Picnic Area.

Wye Cave is interesting because the opening requires the explorer to drop down about 6 feet into the hole, which is the debris from a sinkhole. The hole is located at the right corner of the cavern face. 

Once you enter, the left passage is the main tunnel to explore. However, it should be noted that Wye Cave is one of the most difficult caves to explore due to the need to crawl and shimmy through tight spaces. Those with wide shoulders may get stuck, so always explore with a friend in case you get stuck!

All that’s left to do is head back to the parking lot! During the summer, there is typically a gift stand with souvenirs located near the parking area. There is also a gift shop near the park’s entrance with information and live reptiles.
