Best RV Parks & Resorts near Castleford, ID

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!

We really liked this campground! First, the sites are nicely paved and level, and have full hookups which make an extended stay really nice. There is a picnic table and fire ring for having an enjoyable outdoor experience. there is a huge grass open area adjacent to the site which is nice for outdoor sports.

There is a hiking trail at the edge of the campground which takes you to a nearby winery for a flight of wine and some good food. Very nice for the adults! There is also a path that takes you to a park down at the river which is nice for the kids, and our boys loved the disc golf course. It is huge with 18 holes, but the front 9 are the best, as the back nine have a lot of cheat grass and bushes to lose your disc in.

Nearby there is also a museum about the Oregon trail and how the Three Island Crossing area was used by the settlers... Very interesting place!

Overall we had a great Memorial Day long Weekend.

We enjoyed this campground.  It is a part of a county park set aside for RV's, no tent camping is allowed.  It is FCFS and in October there were a good number of spaces available.   Each site has electric and water.   There are no sewer hook ups and no dump station here, but we were able to find a dump station that was free about a mile away.  The sites are all in view of the creek and there are several paths in the park for hiking and bike riding.  We saw a number of people fishing for trout and several had caught fish.  There are picnic tables with shelters scattered through out,  There are two playgrounds in the main park.  We had excellent cell signals on T-Mobile and Visible.  There are bathrooms but no showers.   It is about 20 minutes to Shoshone Falls and the park there is beautiful.
