I give this place a 🎩🎩 out of 🎩🎩🎩🎩🎩. The place is clean and has both electric and water. Has a dump station somewhere i hear. Way too crowded in spots though. Had possibly the dinkiest fire pit while the spot next to me had an actual round fire pit. Grass was nice bit did have some goat heads. The worst part was the camp hosts. Each spot is supposed to allow 2 vehicles but heaven forbid your car be 2 inches on the "grass". Kids can't even play on trees like kids do. They were out hust to enforce what ever they could. They should also move the river closer to the camp sites. It was too far away. Grass was green though.

Nice little park with a great interpretive center. Clean and neat campsites, restrooms & showers. Even though I was tent camping, my site had power & water. Windy in the afternoon but otherwise pleasant. No privacy as sites are close together. Nice walking trails and access to main highway.

Great quiet place to camp. Water & electric hookups in each rv space. Waste dump site. Walk to the river for fishing. Shade everywhere in common areas, sites are shaded depending on the time of the day. Very relaxing, just had a family reunion there for 4 days. We will definitely be coming back often !!

Stayed in site 2. Level site with water and electric. Gravel back in. Some shade. Sewer dump available. Nice state park museum about history of Oregon Trail. Be advised if you arrive before 2PM check in you will have to wait in the day use area. The museum is located there so we visited it while waiting for check in time. Several rigs waiting as well. Not a big deal. Would recommend and would stay again if in the area. Verizon service was good.

A beautiful and relaxing campground. Lots of birds, heard a barn owl in the tree above our tent, Osprey, King birds, Night Hawks, Swallows, Doves, Warblers, etc plus nice showers with bench option that folds up and down for accessibility and hooks for clothes.. Campsites have electricity and camp fire and picnic tables, very nice and comfortable camping. Some of the trees are close enough for hammocks so my son opted to sleep in a mosquito net covered hammock and said it was nice. The rest of us slept in our tents... Near the river but not accessible due to cliffs. Probably part of the reason there were so many cool birds.
