To get to the rich new lands of the West Coast, there were two options: some sailed around the southern tip of South America during a six-month voyage, but 400,000 others walked there on an overland route of more than 2,000 miles (3,200 km); their wagon trains usually left from Missouri. They moved in large groups under an experienced wagonmaster, bringing their clothing, farm supplies, weapons, and animals. These wagon trains followed major rivers, crossed prairies and mountains, and typically ended in Oregon and California. Pioneers generally attempted to complete the journey during a single warm season, usually for six months. By 1836, when the first migrant wagon train was organized in Independence, Missouri, a wagon trail had been cleared to Fort Hall, Idaho. Trails were cleared further and further west, eventually reaching the Willamette Valley in Oregon. This network of wagon trails leading to the Pacific Northwest was later called the Oregon Trail. The eastern half of the route was also used by travelers on the California Trail (from 1843), Mormon Trail (from 1847), and Bozeman Trail (from 1863) before they turned off to their separate destinations.
