  Linder Point Campground

  Well designed and maintained small RV campground j

  Natural setting with plenty of trees and located near Coralville Reservoir. Paved roads and sites. Ample roam for big rigs, but no pull through sites. Electricity only, with fresh water and a dump station nearby. Modern and clean bathhouse. Open sky at most sites for Starlink. No other amenities at this campsite for children, but there are hiking trails and activities at the nearby reservoir recreation areas.

  Newton KOA

  Highway Roadside Campground Oasis

  Following up on my review from over a year ago, I’m adding a bunch of additional photos as well as an abbreviated post pointing out the HIGHS and LOWS of this roadside pit stop of a campground in very rural Iowa.

  HIGHLIGHTS: (1) Fairly EZ access from I-80; (2) Incredibly well-manicured campground that is both very clean and well-organized; (3) Despite being next to the highway where we were concerned with errant late-night visitors who had no business being at this CG, there’s excellent security and a feeling of being safe; (4) Superb Midwestern hospitality from the KOA staff and camping community; (5) RV slots offer very nice FHUs and fairly spacious areas; (6) Picnic tables & fire rings are in pretty good condition; (6) If you need anything, there’s a handful of just OK restaurants like Cratty Shack Diner and grocery stores like Hy-Vee and Walmart Supercenter in nearby Newton; (7) Spectacularly clean bathrooms and shower facilities; and (8) Well-stocked catch & release fishing pond

  LOWLIGHTS: (1) You are literally right next to I-80, but the CG sits down below the swooshing traffic, so if you’re not looking, you almost forget that you’re camping next to the busiest highway in Iowa; (2) Lack of privacy between sites as there’s not a ton of trees, bushes or brush on the interior of the CG; (3) Most of the RV slots have no shade, so bring your own awning or shelter; (4) Some sites have very close proximity to their neighbors; (5) Some amenities feel dated and could be replaced and / or refurbished; (6) There’s a fairly nasty industrial park, complete with a junk yard and car mechanic garage with accompanying abandoned cars scattered around the entrance that you’ll have to navigate through before reaching this KOA; (7) This really isn’t a good place for tent camping, unless you can convince the staff to let you set up in the shaded area at the north end of the CG; (8) The pool was shut down for maintenance when we visited

  Happy Camping!

  Diamond Lake County Park

  Campground Diamond In The Rough

  Following up on my review from over a year and a half ago, I’m adding a bunch of additional photos as well as an abbreviated post pointing out the HIGHS and LOWS of this county park campground gem in a very rural part of Iowa.

  HIGHLIGHTS: (1) EZ access and just a 20 minute / 9 mile drive due south from I-80 via Exit 201; (2) Incredibly well-manicured campground – very clean and well-organized; (3) Superb Midwestern hospitality from the CG staff and camping community; (4) The RV area looks to be brand spanking-new and offers very nice FHUs and fairly spacious areas as well as most have an excellent view of Lake Diamond; (5) The hiking trails and bountiful fishing spots make this a simply wonderful campground; (6) Incredibly simple honor system to accessing any site on a first-come, first-served basis – simply stick your money in an envelope and pick out whatever location suits you; (7) While basic, the bathhouses were in pretty good condition and very clean; (8) Kid’s playground is fantastic and nearly brand new; (9) Reasonably priced bundles of pre-cut firewood; and (10) Overall the overnight price to stay here, whether RV or tent-camping is very cheap, so great value for $

  LOWLIGHTS: (1) There’s no security gate to prevent any wandering traffic in here, although you are so far out in the boondocks, it’s not really much of a concern; (2) The newly minted RV area slopes down to the lake, but as you park perpendicular, it shouldn’t be an issue; (3) Also, because the RV area is new, there’s no trees or brush, which creates a lack of privacy between sites; (4) Nearly all of the RV slots – save the few that are right next to the lake - have no shade, so bring your own awning or shelter; (5) Some sites have very close proximity to their neighbors; (6) Picnic tables & fire rings, at least in the tent camping areas, are worn-out and in pretty poor condition and should be replaced or refurbished; (7) The water in Lake Diamond is quite dark and murky, so unless you are an adventurous soul, I don’t recommend swimming here

  Happy Camping!

  River Junction

  Great views and location, but not private and not well-marked

  This was our first time camping here. We pulled in around 8pm when it was already dark and there was another car that had just entered the campground in front of us. After driving down the hill, he saw the basic “welcome” and “Pay here” signs next to a 4-car parking area. There were no signs marking where the bathroom was or any directions on how to choose a site. The group ahead of us chose to camp next to the boat ramp, so we circled around the loop and chose a dirt pad on the right side of the loop next to the river. We were very confused because the pictures on Dyrt showed picnic tables and fire rings at every site, but these were nowhere to be seen. It was getting late, so we set up the tent and went to bed. It wasn’t until the morning that we had discovered that we weren’t camping in one of the marked sites! As it turns out, all 4 sites were walk-in sites on grass behind the parking area that had been occupied by 2 cars when we pulled in. The signage didn’t clarify this and we couldn’t see the marked sites when it was dark! The marked sites were pretty close together and they offered no privacy between groups. Additionally, upon leaving we discovered that the toilet was on the top of the hill right by the entrance. Due to the lack of signage and privacy in between the official campsites, I rate 3 stars. It was very beautiful and peaceful, but it was very confusing in the dark.

  Diamond Lake County Park

  Diamond lake

  Clean showers & flush toilet’s. No hand towels. Sites are close together. Some road noise. But overall a nice campground for one night.

  Cedar River Campground

  Good place to go camping with friends and family.

  “This place became my wife’s and daughters’ favorite this year. It is a place where everyone who visits is very kind and respectful. The managers are always courteous and attentive.”

  Deerwood Park

  Cash Only

  Good place to camp. Seems safe and friendly. Only down side is that it's cash only. Who carries cash these days?!

  Lake Iowa County Park

  Very nice campground off the beaten path

  Wife and I met friends here in August 2025.  This was the middle between us & them as we live in CO and they live in NY.  The campground was very well maintained.  Shower rooms & restrooms were very clean and all were functional.  We really enjoyed the long weekend here.  Be advised tho, we were not adequately prepared for the humidity in August.  Being from Colorado where we live at much higher altitudes & we didnt expect the humidity to affect us as it did.  Not a bad thing, we were just used to 15% max and that weekend we saw 90% with 90 degrees.  Wife and I will likely return and see more of the Amana communities in the fall.

  Beyonder Getaway at Sleepy Hollow

  Neat place but it's not flat

  Super nice staff.  We stayed here for a few weeks while working in the area. The land is not flat.  The spots are good and most are pull-throughs but some are too short for a 30' camper.  Would definitely stay there again. 

  We stayed there in October, 2017
