Historical/Interpretive Information/Exhibits, Scenic View/Photo Spot
Three Island Crossing Overlook is located on top of the bluff across the river from Three Island State Park (directions available at the park's education center). 30 miles eastward from this spot, the Oregon Trail left the Snake River and traveled across dry plains until near the overlook, where once again the trail descended to the Snake River. Emigrants would then attempt to ford the river, a risky undertaking that not all of them survived.
Emigrant Remarks
"Wednesday [August] 6 This morning we hired an Indian to show us the ford. After we saw him cross we determined to try it ourselves. We accordingly commenced making preparations. We crossed two slews to the second island. Here we put ox yokes under the wagon loads to raise them, and put four yoke of our best oxen to each of the four first wagons that crossed. These four got over safely. We then sent the teams back to fech the other three wagons... Suffice it to say we all got over, our cattle and all safely." Robert Haldane Renshaw, 1851

Today, the overlook is managed by the State of Idaho. Numerous trail ruts and swales can be seen on the high mesa surrounding the overlook. Amenities include a small gravel path, interpretive wayside exhibits, and parking. The three islands from which the crossing gets its name are visible from the overlook. Parts of the road to the overlook are unpaved but suitable for most vehicles in dry weather.
