We stayed here for a week. The campground is on the northeast end of Holbrook. There are two parallel one-way entrances lanes to the campground: use the right lane to pull up next to the office and check in.

Except for four back-in sites that seem to belong to longer-term residents, all of the RV sites are pull-throughs with gravel pads, gravel yards and picnic tables. Most sites have full-hookups as well as cable connections: a very few have just water and electric (and cable), while the sites marked on the map as being extra long might not have cable. Individual site amenities vary a great deal. Some sites have waist-high pine trees along the border, some have fences between sites, and some have adjacent tree (all sites are open to the sky, though) Some sites have patios that simply have chairs; others come with a gas-powered grill. A few patio and patio-free sites have a pergola, and some sites have small dog pens. Site 66 (likely because the campground is just off of old Route 66) is the ultimate site with a large patio area with a grill and pergola surrounded by a privacy fence. There are also a number of tent and cabin sites.

We stayed in site 50, which was the last site on the east end of our row. All east end sites have a tall fence wall on the right side of the site, likely to block some of the light and sound from I-40 across the way. Our site wasn't long enough to fit our 21-foot truck and 37-foot fifth wheel front to back, but it was a designated wide site so we easily fit our truck between the camper and the fence. Our site was level, and the hookups were all near the back.

The office building has a decent-sized souvenir and convenience store, with a laundry room located on the side of the building and bathrooms located in the back. There is a large playground on the west side of the office with a single basketball hoop and horseshoe pit, and beyond that is the swimming pool. Across from the office is the propane refill station, the dump station, and a communal area with a large petrified log and a small walk-up restaurant where they serve pancakes and host cowboy cookouts in season. There is also a second bathhouse at the back of the campground; all bathrooms are secured with keypad codes.

The best places to walk dogs are either along the dirt pet walk area on the east side of the campground or in the fenced dog park on the west side. The dog park has a grass and dirt surface without any of the usual KOA agility equipment (which means a bit more open space), a single bench, and no dedicated lighting.

In terms of cell service, the best bandwidth I saw on my Verizon Jetpack with MIMO antenna showed 16 Mbps down and 12 up, and other than very occasional buffering I had no problem working and streaming video. The best speed I saw on my AT&T smartphone with 5G was 86 down and 18 up. I tried out the campground WiFi the morning we left and got 3.5 down and just 1 up.

If you're a light sleeper, you may struggle here: I-40 is visible from the east and south sides of the park, and you can faintly hear the semi-trucks as they pass by as well as the occasional train.

We would stay here again if we were in the area.
