Three Island Crossing State Park – Glenns Ferry, ID


We just returned from a wonderful weekend stay at Three Island Crossing State Park. This was our third time here (we camped here the past two summers). This was a very nice campground!

The park is divided into two areas. One overlooks a river, the other does not. Both areas have plenty of well maintained grass areas. Most of the sites are quite large, gravel pull-thrus & back-ins. Interior roads are paved and in good condition.

The campground was very clean, well maintained and quiet. The mature trees throughout the park make the sites nice and cool during the summer. Big rigs can navigate throughout the campground without much trouble as the roads and turns are nice and wide.

We recommend this park and plan on returning the next time we are in the area.


  1. We stayed in a cabin near the river and it was really enjoyable. The wild life is excellent and the grounds are emmaculate. Great place for all. The history is interesting. A must!!!

  2. We just returned from visiting Three Island Crossing in Glenns Ferry and found it to be a beautiful setting to camp. When we drove in to the lower part, there were insects flying all over everywhere so we went back up top where the view is better and the insects seemed fewer. We think we got the best site overlooking the river canyon but We were disappointed and somewhat enraged to find that the flying things are moths and were able to get into our trailer by the hundreds!!!! They were hiding in every crack and crevice and we had to take everything up and clean. Fortunately we had brought our little small Dirt Devil vaccum and sucked them up as they flew, however we didn’t get them all and for the next four days they flew around. The camp host said that this is a once-in-ten-year invasion. I don’t know where they go the other years! They are so dangerous as they fly right in your face and my husband nearly ran us off the road batting at one. We were going to stay two days but left the next morning, as did about 10 other campers. Don’t know if they will refund our money for the second day but will soon find out.

  3. An Oregon Trail site. This park marks the point at which the pioneers crossed the Snake River on their way to the Oregon Territory. There is a small museum in the park, and once a year they reenact the river crossing.
