Pioneer Historic Byway (ID-34)

A 127-mile state byway from the Utah border to the Wyoming border in southeastern Idaho, tracing pioneer emigrant and freight wagon routes. The primary corridor runs on US-91 from the Utah line north to Lava Hot Springs, then transitions to ID-34 through Soda Springs, Montpelier, and north to the Wyoming state line. Passes the Oregon and California trail ruts, Bear Lake overlook, Lava Hot Springs, and the Caribou Mountains. Remote, lightly-trafficked two-lane through volcanic tableland with big sky views.
