This is a very nice campground , mostly set up for RVs with a separate tent camping area. Most of the pull-through sites can accommodate a 35 ft. RV plus tow vehicle, all with full hook ups. The back-in sites on loop B are mostly shorter and probably have the loudest train noise. There is substantial tree cover and decent amount of privacy for the sites. The camp hosts are diligent and very available and the rangers drive through frequently. It is not a party campground and is very quiet (other than the trains!). We didn't use the showers or bathrooms. There is a small play area with a couple of swings and a tether ball pole. There is also a dog area that is not well-marked or easy to find. Overall a great location with many waterfall hikes nearby.

Nice little state park campground. The Columbia River George Trail (bikeway) is located right outside- be sure to bring your bikes! Great location to explore the Columbia Gorge, and highly recommend a stop in at the fish hatchery and the hydro power station! The campground is very pretty, set in the forest below the escarpment and sheltered from the wind on the river. Unfortunately not a great location to set out on foot as you need to walk on the road to get anywhere; but certainly great for bikes and access to the falls and other attractions by car. Back in sites are quite tight for tow-behind trailers. Recommend site B06 for both easy back-in and a clear view of the sky for those wanting their starlink to work!

A very lovely park with the added bonus of easy access via tour trolley, for a price) from the campsite entrance to the many waterfalls nearby. The campsites themselves are relatively small and tight (only one or two spots can really handle a 35 ft. Fifth wheel. This is also a very popular spot due to the distance from Portland and the closeness to the aforementioned waterfalls. If it wasn't for our overall size, I would go here again.

I stayed in the park for 5 days starting August 4, and the weather was amazing. We stayed in site B-7 with a 36 ft 5-wheel and didn’t have any space issues. Several reviews said rv spots were too narrow or short. Spots do slope rgt to lft so have levelers ready. Close to Multnomah falls & plenty of hiking trails. No open fires.

Great spot for quiet camping (except my beagle - apologies everyone!). 🙃 There’s a small pet exercise area just off the trail next to the end of the a / b spots (on the curve). It’s not rooster rock (which is like 2 football fields) but super nice to have when you’re camping and pups get the zoomiez. Photo below is taken from my camping spot. Don’t miss sunrise or sunset on the gorge - totally changes colors.

Very very clean. Unlimited hot water that requires no quarters. Hosts are really really nice. Only reason I didn't give a 5 is because it is close to a train track that does run all night so bring earplugs if you are a light sleeper.

Nice wooded private campsites. Close to all the falls in the area, and good hiking. Friendly helpful rangers and camp hosts. Loved it!

Clean bathrooms. Gorge trail 400 access. Full hookups. There are around 5 first come first serve sites. Some sites are not level. Most likely you will need a few leveling blocks if you don't have leveling jacks. It's off the historic US 30 with many places and trails to see and hike.

The campground itself is great and well maintained- we stayed in one of the tent sites that are nestled in the trees. They are very well spaced out from each other! The only kicker is the highway and train noise. It is constant, and very loud. If you are a light sleeper, or hoping to get away from city noise, this is not your spot!!

Nice park. Very close to everything Columbia River Gorge. It does have its drawbacks. On a hill, so difficulty leveling RVs. Heavy traffic on scenic hwy 30, and the trains. I'd still recommend!

Ok, so I wish I would have read the reviews prior to making our reservation here.........If you love the sound of trains then this is the camping spot for you, lol, especially if you dream about them or should I say you will think you are dreaming about them at 2 am in the morning on the hour all through the night!! Plus I think they switch the tracks up so you not only will hear the trains blaring their horns but you'll hear the clunking of the train tracks switching routes. It was also super windy through the night that we wished we tied our pop up down:/ Yes, the location is nice and everything is clean. Our campsite was B24 and it was not at all private. Close to the wood storage(fire ban so no need for wood) and camp hosts. All campsites seem to have power and water located at them which was nice to charge our phones. Other than that we only stayed the 1 night left a day early cuz of the train activity. We will not be ever staying where trains are running!

I was concerned after reading a recent review about possible white supremacy intimidation. We didn't experience any of that(thank God, but I pity the fool that would try lol) Showers remain closed, bathrooms are open. Sites are pretty private, I liked that! BEAUTIFUL surroundings and nice camp hosts!

DO NOT STAY HERE - WHITE SUPREMACY ACTIVITY My partner and I hoped to stay in Ainsworth State Park on our way up to Seattle. We are queer women. As soon as we got out of our car, a man with slicked back blonde hair approached us with the heil hitler. We did not recognize this motion initially, thinking it was a strange wave, and proceeded to our site. The man followed us up to our site and blocked our path without saying anything. Again, we thought this was strange but moved on to retrieve our supplies from the car. When we returned, we found the man standing in the middle of our site. We let him know it was our reserved site but he would not move or say anything, only turning to reveal sharpie written on the back of his t-shirt: "happy, healthy, wealthy" and some symbols we didn't recognize. We felt deeply unsettled and unsafe and decided to leave immediately. Later that evening, we researched the symbols and learned that they were affiliated with the kkk. We also discovered that the campsite has been host to an aryan festival not long ago. This history, in conjunction with the current age of COVID, George Floyd demonstrations, and recent white supremacist hate incidents in PNW parks, amplified our alarm. We attempted to make a report to Oregon State Parks but have not heard back despite several calls and messages. We will not be staying in Oregon State Parks again and recommend others stay clear.

We tent camped at Ainsworth Campground in the Columbia River Gorge in early April during the week. The friendly ranger told me the campground is 100% full from late April throughout the summer, so book early. This is mostly an RV and car camping campground. There are only 6 walk-in only tent spots. These tent spaces are nestled in trees and have a good amount of room separating one from another. Very lovely. Alert for Light Sleepers: The night we arrived we stayed in a car / RV space near the road. The train noise kept my husband, who is a light sleeper, up all night. The following nights we were in one of the 6 tent only walk-in spaces which worked fine for him. The trees seemed to muffle the train noise. Be aware the trains come through the whole Columbia Gorge with their horns blaring several times a night. If I was a light sleeper, I might choose to stay near but not in the Columbia River Gorge. Other Amenities: This campground is perfect aside from the train noise. It's close to the waterfalls and trails. The bathrooms are large, clean and there are even free showers. There are a few other things like a tether ball court. We found the wood we bought was poor and heard others say the same, so you might want to bring firewood with you.

This park is very clean, a lot of trees & a hike through the campground to two beautiful waterfalls. I only gave it 3 stars because trains come through all night & day.

Great campground, full hook ups. Train does pass nearby. Not too bad in an rv, but a tent you'd probably be annoyed. Trailhead to upper Horsetail Falls is at the west end of campground. Intermediate trail. Campsite B14 had plenty of shade. Most spots have trees for shade.

This is a nice little campground. Right off the highway centrally located on the Columbia Gorge. It's likely going to be a while before all the trails are open. But for a short stay or with kids it's a really nice little spot. I'd like to apologize to the maintenance staff and people who clean the restrooms as I don't normally eat that kind of bacon

Walk in test site was excellent, we certainly thought we found mid-week camping nirvana! Close to hiking trails, private camp sites (only if you choose the hike in option). But the fantasy ended abruptly when the Union trains blew their horns incessantly throughout the night, about every hour! It feels like its coming right thru the campsite. Terrible night if sleep despite the gorgeous setting. What a shame. Camp if you must, and not really sure what the next option would be, but I hope to discover that answer on the next trip.

Thanks again to Oregon state parks! Ainsworth state park is great! Clean, Quite, and close to waterfalls. Yes there is an occasional train but I hear them at home so it didn't bother me. One thing though make sure you have a food supply for the days you stay. Closest store we found was a mom and pop in cascade locks. But they have stuff it just cost a bit more. We stayed in the A loop it was more spacious. Kids liked the swings and tether ball in between hiking.

Hot showers. Individual changing stalls just outside of personal shower. $17/night for walk in site. $24/night for RV hook up. C5 walk in site is ultra convenient. Camped here for 3 nights during our stay in the gorge. You can hear the train at night but after the first night, you don't even mind it. Make sure you arrive and set up tent around 4pm or you will be SOL. This campsite fills up nightly. Don't have exact change? Don't worry! The rangers will give you change in the morning. Campers get showers included in fee. $7 extra per night for an extra automobile. A total steal of a deal here.

Nice clean campground, didn't use the showers but the bathroom was clean. It in a little on the noisy side with trains going by fairly constantly and the 84 right there. The highway noise is constant day and night so it is more like white noise. The firewood they sell in the campground is awful so buy some before you get there. Great location for hiking and seeing the amazing waterfalls. You can hike right from the campground. Stayed in A loop, it is the farthest from the trains and highway. Full hookups and pull through sites in A loop.

We were able to find a walk in camp site last minute for a Friday night this weekend. Our daughter had a water polo tourney close by so it worked great for our needs. Everything was very clean and the staff was helpful and nice. Having said that, if you are looking for a quiet campground this is NOT ideal. The train runs by every 15-20 min all night long. If that doesn't bother you than this is epic place to explore the area.

We stayed at the state park in the fall of 2018. The staff was rude. Their greeting was "we don't open until 4p" rather than "welcome, sorry we can't let you in just now but you can park here if you like and there is a coffee shop down the road with wifi." The trains roared through (it sounded like they were 6 feet from our heads) blaring their horns loudly every 20 minutes 24 hours a day. We had prepaid for 3 nights but left after one even though they have a no refund policy. Awful, just awful.

If you are looking to escape the city noise, get away from people, find some peace and solitude in the wilderness, this is NOT the place to camp. If you want to car camp with all of the conveniences, including hot showers, super clean flush toilets, wood for sale, water and hook-ups in most of the camp sites, a convenient, close location to Portland and to fantastic hiking and waterfalls, then this is a good camground for you. On a busy summer weekend, you will experience the sounds of dogs, kids, generators, RV's and Trucks, radios, and the train runs close-by around the clock. $20 per night for most sites is a little on the expensive side. It is super clean and the host and rangers were very friendly. Thumbs-up on their efforts to recyle, too, with bins for separating trash. Overall, a good place for car camping, but not a place to escape civilization!

This was a nice campsite, but you aren't going to find complete seclusion here. Then again, anyone who thinks they could find it by turning off of a highway into a state park is a little crazy... There is a nice shower house and restroom in the main section of the park. There are only a handful of tent sites, but they are spread out from each other for privacy and space. The going rate for a primitive tent site was a pretty steep at $17 a night. For an extra $3, you could get a full RV site with water and electricity! It shouldn't cost more than $10 (and that's even a little high) to set up a tent on an used piece of public ground with no facilities.

Magnificent waterfalls easily accessible from I-84. Horsetail Falls was a real treat before continuing on to the much more popular Multnomah Falls. Spectacular scenery and very few tourists.

Really enjoyed this well run park. Beautiful tree filled setting. Trains pass by often but not a nuisance on upper campsites, lower sites get a good dose but only added to camping experience to me. Great location for site seeing the area.
