7. National Oregon/California Trail Center (Montpelier, Idaho)
If only those hardy souls who traveled the Oregon and California Trails had it this good: 2,000 miles in one hour. That’s the journey visitors undertake in this living history adventure on a simulated wagon train (with hydraulic oxen), offering hands-on experiences. The center, built at a documented encampment site, has seen increased visitation since opening in 1999. Last year, the museum also housed the “Abraham Lincoln in Idaho” traveling exhibit, showing Honest Abe’s ties to Idaho through artifacts on loan from the National Archives, Idaho Historical Society and private collections.
