Embark on a historic journey dating back to 1821, when the Santa Fe Trail was a commercial highway between western Missouri and New Mexico. The trail, which is about 400 miles, crosses Missouri, Kansas, Colorado, Oklahoma, and New Mexico. See Old West-style prairies, mighty-looking volcanoes, and almost-deserted towns. Don’t forget to stop by the famous Philmont Scout Ranch, the Sugarite Canyon State Park to see the early 20th-century coal-mining camp, and the Capulin Volcano National Monument.
