Three Island

This was a beautiful state park. Very well kept. We only stayed 1 night so we did not get to explore a lot. There is a train nearby so you will hear that. Within walking distance is a winery which has a restaurant and looked very nice. Our site was a back in with plenty of space. There was a small grocery in town. This park had an awesome museum area.

Scenic and Peaceful

This campground sits on the Snake River at the site of what was a perilous river crossing for travelers on the old Oregon Trail. The campground is clean and well tended and sites on the outer lower loop have gorgeous views. An Oregon Trail museum and interpretive center also sits on the property. This was one of my favorite campgrounds.

This was our first time out with the new trailer. We were very impressed with the whole experience. Spot was easy to get into and level. Well maintained area and clean bathrooms and shower area. Kids had fun running around playing and enjoyed the Oregon trail museum. Definitely will use this site again.

Convenient access while travelling

Sites have good shade. Many of the RV sites are close and open.  

There are"companion" sites which can accommodate 2 large campers side-by-side. Many of these are also more private, facing away from other sites.

The cabins are walk-in with parking 50 to 100 ft away.

History and great camping combined

We loves our stay. We were lucky to find a spot during peak season. We actually had to rent a companion site which was more than a single site. However, since we were traveling the state. We bought a annual pass. The discounts it provided paid for itself in no time. The sites were well spaced around a large common area. The grass was lush. There were lots of trees to keep the temps down. The bathhouse was dated. But so am I. LOL. The visitor center is realities new and very very nice. Definitely a must. As others have mentioned, it is where the pioneers following the Oregon Trail crossed. Amazing history. The winery next door was a good visit. They have a full bar and restaurant. We didn't sample the wine, but it's must be pretty good. It's a nice facility. They also run a small campground on property.

This campground has two loops. Both are nice with spacious spots. central lawn area for playing games. Plenty of open space for walks/hikes. Very close nearby is the site where Oregon trail pioneers crossed the snake river. There is a barge and other remnants of history to look at. Two RV dumpsites with water in this park.

Beautiful Park

We got here about 3:30 on a Friday and we got the last spot. They have a lot , but we’re full. The lady at the gate was very nice. It cost $36 for us since we were from out of town. The sites are very nice. Long paved with water and electric on one side and the pick-nik table behind us. It has 1 fire ring/grill in a box area. As crowded as the park seems, it’s very quite. We walked to the river on the hiking path and found some beautiful scenery there. All in all I would suggest staying here, just be sure to reserve first.

Beautiful and Historically Significantl

We were about I hour early and the really nice person at the gate welcomed us and directed us to the Day Use area to wait. Wow! We were blown away. It was a large, lush, green, tree shaded area by the Snake River. There is also a new, really nice, Visitors Center with a film and displays about the significance of Three Island Crossing to the pioneers on the Oregon Trail.

We stayed in the lower loop. It was as beautiful as the day use area. In the center of the loop is a very large common area with 2 1arge picnic pavilions. The large restroom was dated, but clean. The showers were closed for lack of staff to clean. The upper and lower loop have their own 2 way, dual dump stations. AT&T service was good.

Did I mention, there is a trail to the winery next door? Really good wine, full bar and restaurant. Tlhere is also a golf course at the winery. We will definitely be back. We definitely recommend.

A family favorite!

We love this campground in the spring and fall, I imagine it would be hot and full of bugs during the summer months. But it has stunning views (we only stay on the upper loop), great places to explore, and it’s easy to get to. The museum is fun to check out, and they often have events going on that are fun to check out. Our friends say the winery next door is great too, but we’ve never been yet.

Grassy and clean

Ok we thought this was going to be a good spot by the looks of it but our experience was mixed. It was hot when we were arrived at 5pm at around 101, but cooled down nicely as the sun went down.

The site had nice grass and was clean with nice shower facilities in the center of our loop fro site #38. The train goes through several times per night and is super loud!

Overall the sites are close together it was really noisy over the Labor Day weekend and we hardly got any sleep. The tree cover is nice but you can’t see any stars that way.

Nice and clean but won’t go back.

We were tent camping.

Too expensive

Based on the other Dyrt reviews, we originally planned to camp here on August 7 during our cross-country road trip. However, the price just didn’t seem worth it to us. We drove around the campground loops and saw that the sites were pretty close together and it was buggy. There were nice facilities at least. There were a number of sites open despite arriving at 10pm, though it was Wednesday. The total price of$40+ included the site fee+ non-res fee+ motor vehicle fee+ state sales tax. We had just come from paying$20 for a state park campground in Oregon with similar facilities, so it seemed silly to pay so much. In the end we stayed at the close by RV park which added a late arrival fee, so we probably only saved$15. Both campgrounds are near a railroad and local airway, so there is a lot of noise. If we could have done it again, I think we would have just skipping camping in this general area and kept driving a little further.

Nice place to take an RV

Went in mid July and stayed at site #14 which had a great view of the river and the cliffs. We really enjoyed the sunsets from there. Electricity and water (no sewer) temperature was in the 90s and so glad to have AC. Close to town and a winery nearby. Clean and well maintained. Campsites have very little privacy.

Nice campground near the river with several things to keep you busy.

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.
