Philmont Scout Ranch is a large, rugge, mountainous ranch located near the town of Cimarron in the Sangre de Cristo Mountains of the Rocky Mountains of northern New Mexico. The ranch, formerly the property of oil baron Waite Phillips and now that of the Boy Scouts of America, is currently in use as a National High Adventure Base in which crews of Scouts and Venturers take part in backpacking expeditions and other outdoor activities. It is the largest youth camp in the world by size and number of participants.
