This state park offers 2 campgrounds, Wagon Wheel Upper (Sites 1-43) and Trailside Lower (Sites 44-82).  The upper sites provide more long distance views but can also be much windier.  The lower campground is closer to the Snake River and provides a bit more protection from the wind.  Both campgrounds offer nice shade.  There is a dump station on site easily accessible by both campgrounds.  Both Campgrounds offer companion sites at a bit higher fee that are simply wider sides. Two large rigs with slides would not fit in them side by side but can also be rented for just one rig (at the higher price). Two small rigs/trailers without slides fit easily in these wide sites. The best sitse in the Upper campground are 8,10,12,14,16,18,20, 25, and 29.


Both campgrounds are lovely with green grass and lots of trees and a park like setting.


There are terrific trees around the campgrounds…big and tall and beautiful.


The campground sits along the Snake River in an area called Three Island crossing.  The name comes from the mid 1800s when the emigrants were making their way across the Oregon Trail and needed to cross the Snake River.  Approximately half of the 53,000 emigrants that journeyed to Oregon used this crossing. This area has a few islands where they could leap frog their way across the dangerous, treacherous waters. It was a significant feat to accomplish. There is an Oregon Interpretive Center located at the State Park (closed for COVID), some wagons on display, and of course, you can see the wagon wheel ruts across the river.  There is about a 2 mile trail around campground area and along river which passes the wagons and the interpretive center.


Glenns Ferry Recreational Trail goes from the state park into Glenns Ferry. It is a lovely hike which takes you directly through the vineyard and golf course of the neighboring winery.


Yes, the trail goes right through the vineyards called Y Knot Winery. They have not only vineyards, but a tasting room, a golf course, and an RV Park.


The regional trail leads into the town of Glenns Ferry which is a quaint, charming town full of history.  Gus Glenn started a ferry service in 1870 to cross the Snake River. It was a bit late for the emigrants but it certainly still helped others later.


We saw a variety of small wildlife and quite a number of fish jumping in the Snake River. One of the small creeks to the river had a large variety of fish just hanging around. Maybe White Sturgeon? We weren’t sure.
