There was litter everywhere in this campground. Mostly in the small category. Evident that hosts were not focused on this issue. Outhouses were clean and stocked.

We had a GREAT time at Warm River Campground! The hosts were incredible! Everything was clean and well-maintained. The site was beautiful!
@TamaraM7621289 · Camped on Jun 27, 2025 at Campsite #18
We love this campsite. Hosts are so friendly and helpful, and the site itself is beautiful. We love being right near the river

Very clean campground and facilities. Great bike trail and river access. Only downside mosquitoes
@JEFFH5417641 · Camped on Jun 5, 2025 at Campsite #23
Christine, Mike, and Kim were great! They were very helpful and accommodating. We will be back. Our children and grandchildren had a great time.

We had a fabulous Warm River adventure, once again. Weve tent-camped there for years and it is our all time favorite campground. This year since our timing was a little later than usual, we worked with Outdoorsy and had a camper placed on our site. Under that wonderful canopy of trees with the river singing, it was again perfect! Well be back next year as Warm River calls us

Close to the Tetons and Yellowstone.

We stayed in site 27 and really enjoyed it there! We had our own little dock down the steps on the river. The only downside of staying at this site was that it was directly across the river from the platform for others to enjoy, so not much privacy at all. Also, apparently the best fishing is on the other side of our campsite and we had people literally walking through our campsite to get to the favorite fishing spot every single day.

Very clean campground, with lots of hungry trout in the river.
@Katherine76321 · Camped on Jul 25, 2024 at Campsite #20
Hosts were friendly and helpful. Clean vault toilets. Nice, large camp lots. Warning: there is nothing "warm" about Warm River.
@KamasP7A7985F0 · Camped on Jun 24, 2024 at Campsite #2
Our favorite camping location. We go every summer. The facilities are always clean and the grounds are taken care of. We love to fish and float the river. Not to mentioned its a great location to take day trips to West Yellowstone, Island Park or to go into Yellowstone National Park. This year was the most excellent due to the camp hosts. They worked hard to make it a great experience. Super friendly and approachable.

Warm River is an amazing campground. Floating the river is always fun. Lots of beautiful birds. We visited Mesa Falls. Had a great huckleberry milkshake in Ashton!
@RussL6390095 · Camped on May 19, 2024 at Campsite #4
We enjoyed our stay at Warm River, but it was marred by the theft of a sleeping bag that was left to air out while we ate breakfast in our camper. Apart from that, the place was well-kept and beautiful.
@JohnA6427447 · Camped on Sep 13, 2023 at Campsite #4
One of our favorite all-time campgrounds! The camp hostess and host were incredible. They are the absolute best hosts we have ever had. Mesa Falls and Teardrop Lake are close by and great places to visit. The hike from the campground is great. Just an incredible place to be!
@DonWC30C75E3C8 · Camped on Sep 10, 2023 at Campsite #23
Best camp hosts very helpful. A lot of bear activity
@JessicaM36C796 · Camped on Jul 14, 2023 at Campsite #16
Our camp was near the river and fully shaded. Just perfect!
@Shaunt594A6C25 · Camped on Jul 2, 2023 at Campsite #18
The camp hosts this year were amazing!! They were kind and yet kept the campground clean and orderly.
@MarshaS5838305 · Camped on Jun 30, 2023 at Campsite #18
The camp hosts were the best we have ever had. Donna and her husband made our stay delightful!
@DedraW7E0EA0BB · Camped on Jun 28, 2023 at Campsite #19
Such a beautiful area! I enjoy the trail for walks/runs, husband loves the river for fishing. So much to see around the area too. Camp hosts were AMAZING! We just loved them! Also, I’ve NEVER seen such clean camping restrooms EVER! We love it at warm river, we don’t love the mosquitoes…but love the area it’s beautiful!
@RenieG0F545709 · Camped on Jun 28, 2023 at Campsite #15
Clean campground with level spots for tent camping.
Lots of mosquitos because it's right on the river.
Tenters didn't have parking right at their spot which meant schlepping stuff back and for to the parking lot. That was a drag.
There is firewood for sale at $8/bundle. It was not great wood and there was no kindling available.

Great camp hosts this year (2023). We stayed in site #2 which is one you reserve. The grounds are well cared for and the bathrooms are clean. It’s one of our favorite campgrounds to stay at.
@BrenanD2B4C1A8 · Camped on Jun 16, 2023 at Campsite #18
Great camp host and great place to camp
@MaryLeeRE9A5C8 · Camped on Jun 12, 2023 at Campsite #18
Campground, landscape and toilet facilities were very well cared for. Wonderful campground.
@JohnR2194126 · Camped on Sep 1, 2022 at Campsite #15
Lack of hand cleaner in the potty forces one to use the nearby stand pipe. All the hand cleaners were empty
@ChrisT3416096 · Camped on Aug 24, 2022 at Campsite #2
The Hosts were super friendly

I just used PerfectCamp.com to book six consecutive August nights at the most popular campsite in one of the most popular campgrounds in Humboldt Redwoods State Park in California. That is not anything I could have accomplished anywhere else with the ease I did here! Thank you, PerfectCamp! I LOVE this site! You will find me on several other camping sites but the design, format, functionality, and personality of this the best. It’s fresh and clean.

Wow! Woke up this morning to a notification that a favorite had opened at Paulina, and when I went to check, it was there. This membership just paid for itself in the first 24 hours I owned it. Couldn't take the site it conflicted with a trip already set, but it truly was there. Thanks Tons.
