The California Trail carried gold seekers west from the Midwest across the Great Salt Lake Desert during the 1849 Gold Rush.
The route began at several trailheads along the Missouri River and crossed the Great Plains, the Rocky Mountains, the Great Basin, and the Sierra Nevada before reaching California. It was used by emigrants traveling in wagon trains, especially after gold was discovered at Sutter’s Mill in 1848.
The trail was not one single perfectly fixed road. It had branches, alternate crossings, and difficult sections shaped by terrain, water availability, weather, and wagon traffic. The Hastings Cutoff, used by the Donner-Reed Party, became one of the most notorious alternatives.
The California Trail differed from the Oregon Trail even though the two shared much of their eastern route. Its principal purpose was migration to California, while the Oregon Trail primarily served settlers heading toward the Pacific Northwest.
