Snake River Park KOA was average. This KOA, like many others we have stayed at, tried to put us in one of their poor sites, even though I had reserved a site where we could "listen to Horse Creek." They have many pleasant staff members, a good-enough store, and acceptable restrooms and showers. Unfortunately, from our site, there was no path to the restrooms - you had to walk through other people's campsites. Laundry facilities were okay, although a bit pricey at $2 to wash and $2 to dry. This KOA is more concerned with their rafting enterprise than the comfort of the campers. Good things included location to the Tetons.
Yellowstone Park KOA was a disappointment. We had heard that it was excellent, and it was just average. When we checked in, we were "given" the worst site in the place - on the highway, no trees, and a big hole where you step out of your trailer, even after we had asked for a nice site. There were plenty. Returning to ask for a different site was problematic. After saying that we would pay for a pull-through site, we got one, again, with no trees - although there were ones available. Yes, there were tons of things to do there - from getting served a meal to miniature golf. We were there to see Yellowstone with our 8-year old, not hang out in the campground. But the worst - taking a shower was just disgusting. Although they "clean" once a day, they need to up their schedule to a second time during mid-morning. With only 2 shower facilities holding 4-6 shower stalls (in the women's) and 268 campsites, a mid-morning cleaning is essential. Paper towels in the restroom would come in handy for cleaning up the previous slob's hair and toothpaste. We would have liked this KOA to live up to its reputation.
Winnemucca RV Park. What a nice surprise! The owners were very friendly and put us at ease for our first time in an RV park. It was near the beaten path (I-80), but far enough off to get some peaceful quiet. Although few children, our's was happy in the pool.
Brigham City/Perry South KOA. What a dive. From checking in with the redneck meth-head, to being put in an awful pull-through site with dog doo-doo everywhere, we did not feel comfortable or welcome here. This KOA needs a complete upgrade to make level sites and healthy restrooms and showers.
Montpelier Creek KOA is the best KOA we stayed in on our trip this summer. The owners are working extra hard to update the 40-year old camp. New restrooms and showers make for a comfortable experience. There is new concrete everywhere - around the pool, in front of the new A-frame "office and store." Complimentary coffee and internet access are a bonus. The owners are friendly and accessible. An A+ experience!
