Best RV Parks & Resorts near Rupert, ID

Smoky Mountain campground is very close to the entrance of City of Rocks NR and just slightly further is Castle Rocks SP, however, the grounds are managed by the state park. There are some RV/equestrian sites that have 30/50 amp power and water hookups. There is a dump station on the road to the grounds but it was closed for repairs when we visited. There are plenty of pit toilets around the area and the ones we used were quite clean. Spots are mostly back-in but pretty easy access. The camp hosts were very friendly and the camp reservation includes a parking pass for the State Park ($10 value). The RV sites are very private and nicely spread out with pine trees in between. Great views of City of Rocks. Plenty of biking and hiking trails around and TONS of climbing. The visitor center is about 2 miles away and a general store another half mile beyond that. There’s opportunity for gas and food on the way to the grounds (both Albion and Almo have options) but best to get what you need before you leave the major highway. Having hookups at a State Park with such awesome views was sweet and the grounds are very well maintained. Reservations seem hard to come by during the high season.

The relationship between City of Rocks National Preserve and Castle Rocks State Park is still not clear to me as this campground appears on the National Park Service website, although it is an Idaho State Park. That said, the park rangers seem to work cooperatively. This campground is delightful. Located about a 7-mile drive/walk to the entrance of City of Rocks, Smoky Mountain Campground is situated above the valley providing a wonderful view from many sites including space #19 where I parked my campervan.  I believe the walking distance to the reserve could be shorter by taking any of the hiking trails from the campgrounds rather than going along the paved roads which first go away from the City of Rocks then back up again, making a big "U". 

During my one-night stay in February, water, showers and bathrooms in the campground were closed for the winter season. A very clean, pit toilet is located in the equestrian parking lot across from the campground entrance. The distance from the campsites to the bathroom will vary from quite close to about 1/4 mile max. And during the winter season, there won't be much competition for the spaces close to the bathroom, as I was the sole user during my time there. 

In addition to the breathtaking views, the sites offer privacy from 3 sides though all face the loop access road. There are picnic tables, fire rings and electrical power. I did not note if water was available as it would have been shut off in February in any event.  There is a dump station about 1 mile down the road toward the exit. I do not know if it is open in the winter.

Check-in during the off-season is accomplished by envelope collected at the entrance or directly to the ranger who came by in the morning to check-in. The rate was $27 per night. Definitely worth the money to stay in this tranquil campground so close to the magnificent City of Rocks.

This beautiful state park is located right off of the freeway about 7 miles outside of American Falls, Idaho. There is a little bit of road noise at the park because of the proximity to the freeway but it wasn't a bother at all. The views of the river are beautiful and the sunset was amazing. There are a lot of trails to walk on here, and since the park is pet friendly our three big dogs walked the trails with us. There is a disc golf course, although we didn't try it out. The camp host was great. The bathrooms were clean, although only half of them are open in the off season. The only draw back we could see is that the spots aren't very spacious, so if you're new at parking your rig, or if you have a really large rig, it could be a tight fit. We were in a 33 ft TT and the pull through spot (17) was plenty long, but kind of narrow. Spot has 50 and 30 amp hook ups as well as water if you camp during the summer-no water in the off season.

We stopped here on our way home from a recent trip and was a good stop over point. I’m not sure what activities are possible as a destination campground but maybe water sports?

The good:

• Easy on and off from the highway
• Clean bathrooms
• Easy, pull through sites
• Very friendly staff
• They have a grill which will deliver breakfast, lunch or dinner to your site

The mixed:

• It is an RV resort laid out like a grassy parking lot
• A lot of resident campers

The bad:

• The highway was very loud from our site
• No picnic table or fire pit

OVERVIEW: The RV park is part of the county park- beautiful walking/bike path with the creek flowing through. Our back in site was nearby our neighbors, but felt spacious because it's an end site directly across from the camp host. Easy to navigate the concreted roads and the space was easy to back in to. 

Hard to beat $20 for W&E hookups. It's a quiet campground. Trashcans all around the park conveniently. The area as you drive up seems a bit run down, but as soon as you get into the park, it's great. 

There is a free public dump station 1 mile away in town since there is not a dump station on site. 

The park has unisex toilets around the grounds that are vault toilets so nothing fancy. Picnic tables, lots of green space around and the trail goes for at least 2 miles round trip. 

CELL SERVICE: We work remote- We used out AT&T hotspot and had an awesome connection. Reliable for video calls all week. Gradely harshly, giving 4 out 5, only because they don't have wifi and also ideally would have been nice to have sanitizer(especially this year) in the bathrooms. Everything was was lovely. 

GUEST SERVICES: Camphost was super friendly. We came in around 8:30pm on a Monday night with fingers crossed we would find a spot.. and we did with no problem. If it looks full as you enter, keep going past the camphost and you will find the pull thru options. The camp host came over on his gator and shined his lights to help us as we set up. He was very kind. 

NEARBY: Close to downtown Twin Falls with some cute coffee shops and breweries. Also about 50 mins away there is a place called Mammoth Cave that might be the most interesting cave experience you ever experience. I highly encourage it.

Because we'd usually rather be boondocking, we're all about cheap when we actually have to pay for a campsite. And if we're actually going to have to pay, we want the whole shebang -- 50A electric, water and sewer hookups -- because why pay for what we otherwise get for free? The Twin Falls County Fairgrounds delivers on both counts.

The RV Park is located on the east side of the fairgrounds and has 80 spaces with full hook-ups (water, sewer & 50 amp power); and 100 hook-up with (water & 30 amp power). Spaces with amenities cost $21.20, tax included per night, or $106 for a week (buy 5 nights/get 2 free). Dry camping with no amenities is available for $10.60, tax included per night. Maximum stay is 2 weeks. No reservations, everything is first-come, first-served.

Sites are located on grass, with dirt roads throughout the campground. Hookups for water, electric and sewer are located behind your RV. While the site itself is level, that makes it uphill for the sewer run so we wish that they had chosen a more traditional layout. Still, for this price I'm not complaining. Also, if the place actually filled up these sites would be crazy tight; however, during our visit July 2021 they're not even close to 50% capacity, so folks are leaving at least one site between themselves and their neighbors. 

Cell signal strength and data speeds are solid on both Verizon and AT&T. We've been both working and streaming with no issues whatsoever.

There's a separate dump station on site with potable water. The bathrooms are individual units with showers, and are immaculate. If you arrive after hours you have to call the after-hours number on the sign, and James will come out and determine your site and collect your money (cash or check only). The campground occasionally closes for events held at the Fairgrounds, and in 2021 that's for two events. Check their website for details. There was a lot of activity during our stay including equestrian events and even a monster truck rally, so there's lots to keep you entertained while you're in the campground and not out exploring the Twin Falls area.

Filer is a tiny ranching community just west of Twin Falls. Campers will find the surprisingly complete M&W Market just down the street, along with a True Value Hardware. And all of the chains and big box stores are nearby in Twin Falls, only 7 miles away.

No livestock are allowed in RV area, but boarding is available in stables adjacent to the campground for $10 inside/$5 outside. Dogs are not allowed to roam freely and must be under supervision of their owner, either on a leash or kennel. 

So when everything else was booked solid in July 2021, we found dirt cheap FHU sites aplenty at the Twin Falls County Fairgrounds!
