Fills up fast on rv side but great views.  1st come 1 serve. Lots of sites on the water and plenty of tent sites. Decent fishing, lots of bluegill and some crappie.

Great view

We stayed there this weekend. The campsite was perfect right by the lake and the campground was right next to us. Bathrooms and shower house were both clean. Our family is thinking about making it a Labor Day tradition.

Nice, quite camping spots with a serene view of Lake Diamond. ￼cell phone service is great for cricket and Verizon. The camp area was clean. 

Great views  

Arrived on late afternoon Wednesday and there were plenty of primitive spots available (can’t speak to hook ups). The lake is really clean and lovely, with lush grass and greenery all around. Great spot for birds—saw multiple heron, egret and hawks. 

Agree with the other reviews that the sites are rather close together so it could feel a bit crowded during busier times. I luckily didn’t have any occupants in the neighboring sites.

The only downside is you can hear the cars/trucks from highway 85. It’s not highly trafficked so this wasn’t a big deal.

As a solo female traveler, I felt very safe here.

A lush, quiet, pleasant surprise

Stayed one night on my way back to Maine from GNP.  Stayed in #12 just 20ft from waters edge.    Space had water and electric, fire ring and tables.  The only downside is that the lake water was very murky.  I would not want to swim there.  Other than that a great place for a nightover.

Peaceful, well maintained, but murky water

Very nice camping place very laid back and good people around, decent sized lake for fishing , shower houses and restrooms are clean and amazing they even have old style outhouse restrooms at one side of the campground nice trails to walk around as well most campsites have fire rings with grates for cooking 

Great campground 

Kept getting visits from the park ranger over nonsense from being parked on the grass when others were parked on the grass as well especially calling the office first and getting the approval from the person in charge just seemed like they were running ppl off the place was very much opened for Labor Day weekend which was a shock considering past years on the same weekend it was packed , hopefully they allow more freedom in the future was not impressed trash cans were full as well hadn’t been emptied in a while 

Great weekend 

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 &amp; beans, then there’s really just a few nearby options: Subway, Sauced Pizza &amp; 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!
