For decades before the dam was built, Bonneville was popular as a picnic spot for people living along the Columbia River between Portland and The Dalles, and the railroad company maintained an "eating house" for travelers there.[2] Bonneville railroad station was named for explorer Benjamin Bonneville.[2] The name "Bonneville" did not appear on maps until the late 1880s.[3] Bonneville post office was established in 1900.[2]
Bonneville has a warm-summer Mediterranean climate (Köppen Csb).
