The International Music Camp opened in 1953, with a one-week band camp session. Now it runs for at least 8 weeks each summer, and includes programs in music, dance, drama, art, photography, creative writing, drumming, and more. There are sessions for ages from 5th grade to adult. Costs range from $300 to about $500 for a week, all meals and lessons included, depending on your session and if you take one-on-one classes in addition to group classes.
The camp is located within the boundaries of the International Peace Gardens, on the US-Canada border between North Dakota and Manitoba, in the beautiful Turtle Mountain area, a region of rolling forested hills with lakes. When I attended (I won't say how long ago....) students were housed in a "barracks" like building with rows of bunkbeds. We also each had a day on bathroom cleaning duty, KP duty, and so on. There are now new buildings, including a really pleasant dorm that resembles a newer college dorm, so housing isn't the shock it once was.
Students choose the subject they want to spend their week studying, and each week offers several different subjects. You can check their website (internationalmusiccamp.org, I think) for more info; if you pay before May 15th, the tuition is discounted. The instructors come from all over the world, as do the students, and they are generally among the best in their field. Speaking for my experience, I was amazed at how much I improved in a mere week. Now I wish I were younger and could experience all the subjects they offer.
One other benefit for high school graduates are two, two-week sessions for those students who plan to major in music in college or university, and make it their career. These are intensive sessions with both group classes and one-on-one tutoring sessions in playing music, music theory, composition, and more. At the end of each week of camp, there is a public concert (or drama performance, or art gallery show) on the Peace Garden grounds. By then, the campers feel like pros.
For worrying parents, they should know that there is a nurse on-site, and clinics and hospitals within 20 minutes on both sides of the border. I highly recommend the Interational Music Camp both to students wanting to improve at their art, and for parents who are looking for something much more for their kids than water sports and hiking. Neither student nor parents will be disappointed; the memories from one week at this amazing camp will stay with you for the rest of your life!
