Best Campgrounds near Firth, ID

Great place for our overnight stay. Easy access to pull through sites with ample space between the sites. Nice clean bathrooms with showers! Electric and water worked great. Would definitely stay again.

We were excited to find this CG on Dyrt and that it wasn’t difficult to find (in spite of a reviewer’s commenting); but when we arrived, the gate was pad-locked.  (Sign indicated open hours; but not that it would be closed for the season.)  

Fortunately, we went .5 mile further and found a small dry camping site— maybe 4-6 vehicles could be accommodated.  Sign there indicated that there was a 5-day limit for camping.  A couple of other vehicles came in; but none chose to join us for the night.  Camping area is right by the gravel road and there was traffic coming & going late into the evening & early in the morning; but regardless it was a great site w/ privacy from the road.

The place is big and the locals certainly come here. Each site has a picnic table, a fire ring and some grass. They’re fairly level. The bathroom and the showers are huge and very clean. Small trees at each site now so until they get big, there won’t be much shade in the summer. Very close to the town for the soaks. It’s very close to the highway which is a plus, but there can also be some traffic noise. Beautiful views.

This place was hard to find - I almost gave up. The GPS directions and coordinates on this app are both wrong. Take Warm Slough Rd off 4000 N. Ignore the no trespassing signs- they refer to the land on either side of the road. You can also search "Warm Slough Campground" in google maps. There is a smaller campground at the end of the road, and a larger one with pit toilets if you hang a right at the brown sign with the various camping rules.

Lots of options with fire rings and tables. Really nice and peaceful once you find it :-)

I reckon it’s a decent place to spend the night. The road up although somewhat steep at times can easily be accessed without 4WD. A few nice sites right as you enter with fire pits & picnic tables. Unfortunately most of the sites are right next to the road, which the locals seem to rule with their 4 wheelers and side by sides, making lots of noise and dust.

This place is in the middle of nowhere with no cell service. I drove all the way out here only to find the gate to someone’s ranch with a no trespassing sign. Super frustrating.

There are extra pull offs by the river before the main area, perfect for car camping!

Great camp ground with spring nearby

This park has very clean bathrooms, great showers, and grass so thick you don’t need to wear shoes! Great setting, helpful staff and out in an area of dark skies. Electricity went out at one point our first night here but we have solar panels so we’re ok.

The KOA is just off US-30, so easy to find. Our GPS and Waze did not have the exact address, but you can easily see the KOA sign coming in from the east. We were traveling with another couple and there were basically two marked check-in spaces. You have to pay attention to where you position your rig so you don't block office car parking. We had reserved a premium K-9 site and were assigned site 102 at check-in. Site 102 was 1 of 3 premium sites next to the office. The problem with site 102 was 1) there was a truck parked there with no owner in sight, 2) trees that would have scraped the top of our 5th wheel, and 3) a very difficult and tight back-in swing on this 90-degree site with our 40' rig. You need to be an expert backer, or very lucky, to clear the trees at the entrance of this site if you're in a larger rig. Sites 100 and 101 do not have these same obstacles and with the river view, are arguably the best sites in the park. We went back into the office to request a different site and were assigned a non K-9 premium back-in site, 200, in their new area. We would have enjoyed the original site as it does have a nice river view. Sites were under construction in the 200 area and each site is highlighted by 7-inch high and 6-inch wide cement curbs. Whoever designed much of this CG did not understand RVs. It was challenging to back into your site as there are also cement barriers to protect the sewer hookups off the curbs in front of sites on the adjacent pull-through sites. We almost tore off a snap pad getting too close to a curb as the curbs are not sloped to prevent this and based on the markings, a lot of tires have fallen victim to these curbs. Also, we had to be very careful going up and down our steps as you have the curb there as well. While we were getting into our site, a 45’ class A was trying to get into pull-through site 221 across from us. Just trying to make the turn onto this row, he ran his rear tires up on the curb around the shower/laundry facility. He still had his toad attached and had to disconnect it to avoid damaging his vehicle. Hopefully, the management of this park will mark that site for shorter rigs as he also had problems clearing the curbs when departing his site. Their free Wifi was decent. We got 3 bars on Verizon and no issues getting a shot to the north sky for Starlink as there are no mature trees in this new area. There are plenty of other CG options in the area, so we will not stay here again. The main positive of this CG is the staff. They were friendly and accommodating when we requested to change sites. They also credited us the diffrence in cost since we didn't get the K-9 site, without us asking for the credit.

Off the main road. Good location with swimming, Zip line golfing and hiking.

The campground itself is nice. Nice spots, beautiful river and waterfalls, and close to Lava Hot springs. The trains; however, were a drag at night. Not many ran during the day but at night we counted 8 that went by. The tracks are only about 100’ from most of the spots. The real kicker is, because there’s a crossing to get into the campground, the trains blast their horn literally right as they pass you. Like excessively so, unnecessarily so. It was not a great nights sleep.

Beautiful campground camp host was very helpful

Had some bugs. Lots of trees, some spots have river access. Wasn’t to busy

Great spot just 45 minutes out of Idaho Falls. Lots of sites, many are right by the river.

There are a few bathrooms along the road but may be a bit of a hike from some sites.

River is refreshing and nice to watch. Only complaint is the garbage left behind. We easily filled a garbage bag full of others trash when we first arrived. Remember to pack your garbage out to keep places like these pristine.

We arrive without a reservation and they were able to accommodate us. Brinley staff clean bathroom and showers. Nice view of the lake and had grass for the dogs to do their business. It was a gravel lot a pretty much leveled. It’s a great in between place going towards Yellowstone.

Bathrooms and showers are very clean, some sites are widely space, but some are crammed together, otherwise, a typical KOA.  EXCEPT it is expensive and they add on extra fees for people, pets, and vehicles; never stayed at a KOA that does this.  Oh, the road noise is pretty bad also.
