Summer months bring higher occupancy to RV parks throughout the region, particularly during peak tourist season from June through September. Cell service varies significantly between campgrounds, with stronger signals available at locations closer to towns like Sheridan and Buffalo. Most RV campgrounds in the area welcome pets, though specific restrictions may apply. Dump stations are available at several facilities including Peter D's RV Park in Sheridan and the Burgess RV Dump Station. Navigation to some campgrounds requires careful planning, as mountain roads can present challenges for larger motorhomes. Sites at many parks feature gravel pads that may require leveling blocks, especially after periods of heavy rainfall when ground conditions can change.

"The laundry and bathrooms were clean. The campground was clean. A fenced in area for dogs to run and play was fun. We would go back."

This is a huge area with plenty of spots on grass. Plenty of room for any size RV. 360° gorgeous views.
Arrived early mid-week hoping to snag one of the riverfront spots (#3 and #4) but both were taken. #2 was the easiest to access and was fairly private despite being right off the road. Traffic is minimal. Walked along the gravel road enjoying the rock formations and explored the river at various points. Not sure anyone was servicing the bathrooms in late August, have your own TP handy ! Otherwise a great quiet spot to enjoy the night sky. Would stay again.
The staff are very helpful. Showers and laundry are clean and tidy. Sites are spacious gravel, level with grass between. Road noise is low. We're here 1 nite and we're comfortable.
Easy to find, plenty of spots at a nice distance from others, great ATT service, gravel roads well maintained, we parked a 25’ RV towing a car and had no issues with access or mobility/turn around needs.
This delightful spot at the end of the toad is now day use only - no camping allowed. (As of Sept 2026.) There is a nearby campground with 7 sites that you pass on the way in. The road is one lane good gravel.
Was going to go to federal site, but they were closing as we pulled in. Found the great free dispersed site just down the road from the paid site. A little bumping coming in on the road, but not bad. Easy for 2WD, just go slow. Had a burn ban in the park, so no campfire…but the views were great!
It’s flat land and easy road to access. Just find any open area and drive up. I enjoyed this spot a lot.
Stayed here end of Sept. No wind and only a few other campers. Marina was closed. Beautiful and peaceful. Uh
This Camp!! site is fairly level right on the creek. We are the only ones here beside the Camp!! post. It’s absolutely gorgeous peaceful.

Fishing access points: The Tongue River Campground offers riverside camping with multiple fishing spots within walking distance.

Nature trails: At Deer Park RV Park, campers can explore the half-mile nature loop near the front of the property. "One of our favorite features was the nature trail near the front of the CG—about a half-mile loop—where we spotted several deer. A peaceful walk and a nice touch to the stay," reports a recent visitor who enjoyed the wildlife viewing opportunities.
Historical sites: Several campgrounds provide access to significant historical landmarks. "We visited here in June of 2019. Very clean and well taken care of campsite close to the Little Bighorn Battlefield National Park. Custer actually rested his troops at this site just prior to starting the battle," explains a visitor to 7th Ranch RV Park, highlighting the area's connection to Western history.
Mountain proximity: Many campers choose Dayton-area campgrounds for their access to mountain recreation. "Right off the highway leading into the mountains. Has a great coffee shop and bakery on the property. The owners are fantastic people as well. They don't have a TON of spots, and they're popular so if you're looking to go this way... call ahead!" explains a visitor to Lazy R Campground.
Clean facilities: Campground cleanliness rates highly in visitor reviews. "The bathrooms were spotless each time I used them, regardless of time of day. The showers were very clean, the temperature fluctuated some while using, but nothing to complain about," notes a camper who stayed at Sheridan/Big Horn Mountains KOA, appreciating the well-maintained facilities.

I highly recommend this as a place to stay," writes a visitor about Foothills Campground, appreciating the riverside location and town proximity.

"Sites at many parks feature gravel pads that may require leveling blocks, especially after periods of heavy rainfall when ground conditions can change," notes a visitor to Tie Flume Campground, highlighting the importance of checking seasonal availability.
Elevation considerations: Higher elevation campgrounds experience significant temperature changes. "This campground is over 8000 feet with no electric. There are several sites that are great for solar," explains a camper about Tie Flume Campground, noting the elevation challenges and power solutions.
Water availability: Access to water varies significantly between campgrounds. "Be aware that you will have to arrive with water in your tank if you are in an RV.

Wildlife viewing opportunities: The region offers excellent wildlife observation possibilities. "We enjoyed this park however, our site was not level and the water had an unpleasant taste.

Town accessibility: Peter D's RV Park provides convenient access to nearby attractions. "First off, Peter D is great. I was having an issue with my RV and he took notice and lended me a hand.

There is currently a fire ban so no fires but that was to be expected," explains a visitor to Deer Park RV Park, noting the spacious layout but seasonal fire restrictions.
Hookup logistics: Full-service RV parks near Dayton offer varying levels of hookups. "We have a 38 ft fifth wheel and there is plenty of space. Their cabins look a little run down, but if you need a cheap, quiet, close to the interstate place to stay with your camper, this is a nice stop," shares a visitor about Foothills Campground, providing practical information for larger rigs.
Cell service variability: Mobile connectivity varies throughout the region. "We had two bars on Verizon and four bars on T-Mobile.
