Best Dog-Friendly Camping near Marshalltown, IA

This campground has many sites to choose from - RV with hookups as well as some non-electric tent sites. There are quite a few activities in Marshalltown, and it is within the Marshalltown city limits.

The downside is proximity. It is right next to the highway. When I was there in a tent, the hog trucks would drive by all night (loud and smelly). The RV sites are closest to the road, so maybe it is not so bad in an RV, but it is not particularly enjoyable in a tent.

Pros:

+ Marshalltown has quite a few places to eat

+ Nice bike trails (and a great bicycle store downtown)

+ It is near the Iowa River

+ Nice park in general with activities like a dog park

+ Camp host on-site

+ Decent sized campsites

+ Playground for the kids

Cons:

+ It can get busy on a summer weekend

+ Noisy - right by the highway

+ Mosquitos are really bad here

While it was our first time camping in Iowa, we were extremely lucky to land upon this slightly hidden fresh water centered campground just a 20 minute drive south of Route 80 near Montezuma, wherein one needs only follow Road#63, before coming across Diamond Lake County Park. With the fall colors being in full bloom when we visited, the entire campground was awash in bright yellows, reds and oranges from the changing colors of the leaves. Also, as we were visiting in mid-October, versus some of the other reviews here, we found that we had the place mostly to ourselves, which made for a rather peaceful sublime respite we were searching for. 

As for the campground itself, what we enjoyed most was how this location is, for the most part, very well organized in keeping the RV'ers and 5th Wheeler crowds together, while preserving a nice slice of verdant lakeside pasture for us primitive camper types. Each of the sites for camping come equipped with (in most cases) fairly new aluminum picnic tables, fire ring with folding BBQ grill. While we didn’t stay in the RV areas, given our tent-pitching persuasion, what we did see was fairly impressive and looked altogether rather brand new with freshly poured concrete slots and fairly mint-looking RV hook-ups (50 amp electric and water) and this same area also boasted a brand new restroom facilities. 

Obviously, the main attraction here is Diamond Lake itself, with its more than 90 acres of fresh water, albeit murky fresh water, was certainly a hit with this camping family. We enjoyed being able to get out on the lake with our kayaks and canoes as well as go for very long walks around the circumference of the lake itself, with which you will find simply splendid trails. And if that’s not enough exploration for you, then head further inland and away from the lake to explore this parks other 660 acres of grassy prairieland. 

From an amenities standpoint, there’s a decent amount, including: three shower houses, four shelters, 2 dump stations, three his / her latrines (some much more dated than others), boat ramp and fishing dock, a dedicated fish cleaning station and what looked to be a fairly new kids playground. In all there’s a total of 120 sites to choose from, with 80 designated for RVs / 5th Wheelers and 40 earmarked for primitive camping, which do not come with any electric, which was on one hand the biggest bummer, but on the other hand, offered up front-row access to lakeside camping bliss as many of these primitive campsites are located right on the water’s edge. 

Insider’s tips? Here’s a few: (1) Check-in is self-registration and is done onsite, so net-net, this place is first-come, first served as no online or advanced registration is taken. While we didn’t mind this, and given that we arrived right around noon as folks were actually checking out, we got the ‘pick of the litter’ of campsites. Electric sites are $20 / night and non-electric are $10, so this place is incredibly affordable; (2) If you are looking for some grub nearby after growing weary of another meal of franks & beans, then there’s really just a few nearby options: Subway, Sauced Pizza & Pub, Casey’s and Yolanda’s Tacos over in the little town of Montezuma; (3) While there are actually few different campgrounds here at Diamond Lake, for primitive campers, the best sites IMHO are located as far southwest as you can possible go around the lake, where there’s more than a dozen or so sites that sit right in front of the water and present a completely isolated surrounding. 

Happy Camping!

Wonderful trails, lots of space.  Access to DM River, has nice pond, playgrounds, just a beautiful area.  Fishing not the greatest, Pond is silted to about 9ft deep, have caught few small bass, bluegill.  Never tried the river here, but is known for big cats.  Camp sites are best around, large flat white rock cinder size area with picnic table, fire ring.  Sites are well spaced.  Shaded.   Double lane dump station.  Close to home, can usually get site without reservation, IF you roll in on Wed.  By Thurs night, it's full.  Few reservables, 90% i'd say are first come.  The way it should be in my opinion.

This place is great! There are 10 beautiful campsites, all with new picnic tables, fire ring and cement pad so you’re chairs are actually level! The fire ring even has a grill you and flip over the fire to cook. There is a vault toilet up on the hill where the campsites are. FYI - the women’s side did not have a lock. The sites were very spacious, some massive and very spread out. You could see neighbors but you aren’t on top on them. And it’s free! You can stay for up to 14 days. They do have registration cards up on the board to complete and post on your site. I had 2-3 bars of LTE via AT&T. The closest gas station is about 7 minutes away and a grocery store about 10 minutes away.

Let’s talk ticks!! I travel with my dog and during the 3 nights I stayed, I was constantly removing them from him, myself and within the inside of my van. They always got on his feet every time he used the restroom and made their way inside. If you travel with a pet, check them constantly and make sure they are on a tick med!

This site was great, it has a reserve site to its right, (the people never showed up) and a FCFS site to the left. No one showed up there either and it was Father’s Day weekend! Super quiet and relaxing. Each site towards the front of the 400’s is BIG. You have plenty of room for 2 vehicles and two sizable tents. There was four of us and a dog.

A couple minor complaints that I developed would be that it is right next to the golf course so there is a lot of near by traffic, and people like to cruise on motorcycles and drive muscle cars through the twisty roads. The nice bathroom in the #300s camping area is a bit of a walk BUT has showers and really clean toilets. Some of the cleanest I’ve seen at a campground in Iowa. DO NOT USE THE “TOILETS” in the #400s area, they are dirty and basically a hole in the ground.

Another downside is that things are pretty spread out, and with it being pretty hot out we weren’t able to walk miles to get to the different trails at the park. The short trails we did walk on were nice and up kept though.
