Best RV Parks & Resorts near Marengo, IA

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!

Little Bear Campground is located right off I-80 at the West Liberty exit. It is right next to a trailer park. There are a few tent sites ($22/ night)and Rv sites($33/night). We pulled in late to stay the night. It had full hook ups with a fire ring and picnic table. The spot was good sized and clean. There is an office/ gift shop and a convent store within walking distance. There is 2 cute little cabins which run $49 a night. There is a pool(closed for season), and a playground for kids. I was surprised that the interstate noise was much quieter than I thought it would be. All and all it was a pleasant place to stop over.

Check-in was quick and easy. We proceeded to back-in site 61 with water and electric(50/30/20 AMP). We were one and done on what we thought might be a more difficult back-in, but there was enough level ditch in front to allow an easy swing. Our site was somewhat level, but we did have to put blocks under the passenger-side tires. We could back far enough in our site to park our F-450 in front of our rig at an angle and still put our back deck out. We got 2 bars on Verizon and could put out our Starlink. They have a double-hole dump station that can be accessed in both directions. This large COE has a variety of sites, with the 300 loop being full hook-ups. The sites down by the boat launch have electric only and tent sites. There are shower houses throughout the CG. Compared to other COEs we’ve stayed at, the sites here are closer together. The CG wasn’t full during the week but filled up on the weekend while we were there.
