Horses and llamas are used for many of these courses. The natural history of the winter season can be explored through courses in snow ecology, wildlife ecology, and photography to provide students with a better understanding of Yellowstone's special winter season. Institute courses are generally limited to 10-15 students to ensure and individualized instruction. The Institute takes pride in its tradition of conducting high quality, yet informal and relaxed courses. The Institute facility at the Buffalo Ranch, where about half of the courses take place, creates a comfortable, retreat-like learning atmosphere.
Students prepare their own meals, often sharing recipes or pot lucking their specialties.
During the summer, meals often take place on the Bunkhouse back porch which overlooks the Lamar Valley to the west. After evening classes or a campfire, students enjoy a cool and restful Wyoming night in the Institute's log cabins. Classes having special requirements, such as horses, llamas, kayaks, or multiple instructors will cost more. Courses taking place away from the Lamar facility involve camping or staying in park lodging or local motels. Over the past two decades, the Yellowstone Association Institute has evolved into a respected educational program.
