Geode State Park campground is one of those places that feels like it’s stuck in a time loop, but in the best way possible. You’ve probably seen the signs off Highway 34 in Henry and Des Moines counties, pointing toward a patch of green that looks like any other Iowa woodlot. It isn’t.
Most people show up here looking for the namesake stones. They want that satisfying crack of a hammer hitting a dull grey rock to reveal a sparkling, hollowed-out interior of quartz or calcite. But honestly? You can’t actually keep the geodes you find inside the park boundaries. It’s a bit of a bummer, but that’s the law. If you want to take one home, you’ve got to head to the private "dig sites" just across the Skunk River or down by Lowell. Despite that little rule, the campground itself remains a cult favorite for folks who want to escape the noise of more crowded spots like Ledges or Maquoketa Caves.
What it’s really like staying at Geode State Park campground
The first thing you’ll notice about the Geode State Park campground is the layout. It’s split into two main sections—an upper and a lower loop—and they have very different vibes. If you’re hauling a massive 40-foot rig, you’re going to be sweating bullets trying to navigate some of those tight turns in the older sections. It’s doable, but it isn't exactly a "pull-through paradise."
Most of the 80 or so sites have electricity, which is a lifesaver in the humid Iowa summers.
You’ve got 50-amp service at many of the spots now, thanks to some much-needed infrastructure updates over the last few years. The pads are mostly gravel, and while some are perfectly level, others will have you stacking leveling blocks until you feel like a structural engineer. It’s part of the charm, I guess. The shade is the real selling point here. Huge, old-growth oaks and maples dominate the canopy, which keeps the temperature about five degrees cooler than the open cornfields surrounding the park.
The Lake Geode factor
Let's talk about the water. For a long time, Lake Geode was... well, it was a mess. It suffered from major siltation and water quality issues that plagued many Iowa man-made lakes. But the Iowa DNR put in some serious work. They drained it, dredged it, and basically gave the whole basin a facelift.
Now?
The 187-acre lake is pristine again. The swimming beach is a huge draw for families staying at the campground. It’s got that classic 1950s summer camp feel. You’ll see kids with neon-colored floaties, parents reclining in camping chairs with half-melted coolers, and the smell of charcoal smoke drifting from the nearby picnic shelters. If you’re a kayaker, this is your spot. There’s a "no-wake" rule across the entire lake, meaning you aren't going to get tossed around by some guy in a fiberglass speedbot going 50 miles per hour. It’s quiet. You can actually hear the birds.
The "Geode" mystery and where to actually find them
People get confused. They arrive at Geode State Park campground expecting to walk out of their tent and trip over a sparkling crystal.
It doesn't work like that.
Geodes are formed in the Warsaw Shale, a geological layer that’s particularly thick in this corner of the Midwest. Millions of years ago, this was all an inland sea. As things shifted, cavities formed in the soft rock, and mineral-rich water seeped in, slowly—very slowly—crystallizing over eons.
Inside the park, the "Geode Trail" is a fantastic hike. It’s a roughly 1.3-mile loop that takes you through some pretty rugged limestone outcroppings. You’ll see geodes embedded in the creek beds. They look like lumpy, oversized potatoes. But again, look but don’t touch. The park rangers are pretty strict about the "leave no trace" policy. If you want the thrill of the hunt, check out some of the local farms in the town of Lowell, just a few miles south. They’ll often let you into their creek beds for a small fee, and you can keep whatever you can carry.
Practicalities: Bathrooms, Bugs, and Connectivity
Nobody likes to talk about it, but the bathhouse can make or break a camping trip. The facilities at the Geode State Park campground are respectable. They aren't five-star resort quality, but they are modern, tiled, and generally kept clean by the park staff. The showers have actual hot water, which isn't always a guarantee in state parks.
- Connectivity: If you’re hoping to "work from home" via your Starlink or a hotspot, it’s hit or miss. Verizon usually has a decent signal near the park entrance, but once you drop down into the lower camping loops, the trees and the topography conspire against your Zoom calls.
- The Bug Situation: It’s Iowa. In June and July, the mosquitoes can be aggressive. If you’re camping near the lake, the gnats are also a factor. Bring the heavy-duty spray or one of those Thermacell gadgets.
- Supplies: The park is somewhat remote. New London is the closest town for a quick grocery run, but for anything serious, you’re driving 15-20 minutes into Burlington.
Why this park feels different from others in the Midwest
There’s a specific kind of silence at Geode. Because it isn't right next to a major interstate, you don't get that constant low-frequency hum of semi-trucks. Instead, you get the sound of the wind through the hickory trees. It’s one of the few places where you can still see the Milky Way clearly on a moonless night.
The trail system is also underrated. While everyone flocks to the lake, the woods surrounding the campground are full of white-tailed deer, wild turkeys, and the occasional pileated woodpecker. It’s a birdwatcher’s dream. If you’re quiet enough in the early morning, you’ll likely see a doe and her fawns drinking from the edge of the lake near the boat ramp.
Navigating the booking system
Iowa’s state park reservation system can be a bit of a headache if you aren't prepared. You can book sites up to three months in advance, and for holiday weekends like the Fourth of July or Labor Day, you’d better be online the second the window opens.
However, Geode usually has "walk-in" sites available.
These are first-come, first-served. If you show up on a Tuesday morning, you’re almost guaranteed a spot. If you show up Friday at 6:00 PM? Good luck. You’ll likely be driving back to a motel in West Burlington.
One thing to keep in mind: Iowa recently changed some of its park fees for out-of-state residents at certain high-traffic parks. While Geode hasn't always been on the "premium" list, always check the current DNR fee schedule before you pull up to the iron ranger (the self-pay kiosk).
Beyond the campsite: Local highlights
If you get bored of sitting by the fire, there’s actually a fair bit to do within a 20-minute radius.
- Snake Alley in Burlington: Billed as the "Crookedest Street in the World" (sorry, Lombard Street in San Francisco), it’s a weird, brick-paved architectural marvel that’s worth a quick photo op.
- The Skunk River: If the lake is too calm for you, the Skunk River offers some great fishing and canoeing opportunities just outside the park limits.
- Lowell, Iowa: This tiny unincorporated town is basically the geode capital of the world. There’s a small shop there that sells incredible specimens if you failed to find any on your own.
Essential Next Steps for Your Trip
To make the most of your stay at Geode State Park campground, you need a plan that goes beyond just packing a tent.

First, download the offline maps for Des Moines and Henry counties. Cell service is spotty once you enter the valley, and you don't want to be guessing which gravel road leads back to the main highway.
Second, check the Lake Geode water status on the Iowa DNR’s official beach monitoring website. While the restoration has been a massive success, heavy spring rains can sometimes cause temporary spikes in bacteria levels—common for all Midwest lakes—and it’s better to know before you put the kids in the water.
Finally, if you’re serious about seeing the "raw" side of the park, pack a pair of waterproof boots. The best geode-viewing areas along the creek beds are often muddy and slick, even a week after the last rain. Forget the flip-flops for hiking; you’ll regret it the moment you hit the Warsaw Shale slopes. Don't forget to bring your own firewood, or buy it from the park host; moving wood across county lines is a big no-no because of the Emerald Ash Borer. Get your reservation sorted, prep for the humidity, and enjoy one of the quietest corners of the Hawkeye State.
