Yellowstone Association, a non-profit organization, offers learning adventures in America's first National Park. The association's 3 and 4-day lodge and learning programs, the equivalent of summer camp, are guided by experienced naturalists and include a wide range of activities such as hiking, wildlife watching, painting and photography. Children 8 years of age and up are welcome on all family programs. Kids must be at least 12 years of age to participate in all other lodge and learning programs. One-day wildlife safaris (no minimum age) can be booked through Gardiner, MT based Flying Pig Adventure Company. Yellowstone Association also offers private one-day tours of Yellowstone National Park.
