Camp Marrowbone | YMCA Seven Fires

Y Camp Marrowbone

YMCA Camp Marrowbone provides a safe and supportive environment for kids to learn, explore, and grow. We focus on meeting each camper where they are and working with them to realize their greatest individual and collective potential. Our goal is to teach life skills through the character traits of Caring, Honesty, Respect, and Responsibility and traditional Lakota values. Our weeklong camp experience results in new friendships, the opportunity to try all sorts of activities, and a place to call home.
