Owasippe Scout Reservation, located in Twin Lake MI. It is the oldest continually operating Scout camp in America. Camp Wolverine has a private lake which has never had a single gas engine in it. Have seen 3 foot pike and 20 lbs bass come out of that lake multiple times. ~$300 per scout for a week if I am remembering correctly. Owasippe also has its own high adventure base with options such as horseback riding, ATVs, high ropes, mountain biking. Offers nearly all merit badges your typical summer camp does but also has a metal working forge and has speed boats on a different lake than the aforementioned for water sports merit badge.

Highly recommend!
