Lost Gold Trails Loop

Follow the Lost Gold Trails Loop through rolling terrain in eastern Idaho. This byway runs along an early Gold Rush route, historic sites like the Heritage Hall Museum, the gateway to the Nez Perce Historic Trail and Beaver Canyon. When the gold near Spencer disappeared, opals took over, and you can still dig for opals in this area today. During the spring and fall, this route often features wild game grazing along its length.
