★★★★Eric (Tesla)Decent place for family camp. Food was definitely rough but didn't expect much tbh. Definitely a lot of fun for the kids!
★★★★★Charles XavierI have never attended this camp but every year around the great American holiday they have a nice fireworks display that you can see over the trees in the nearby areas.
★★★★★Steven Horowitz54 years ago our youth group from Grand Rapids would enjoy your camp. The Biot..... I still remember the names of campers from Chicago. Leah Slavensky, Rael Slavensky, Brooke Garber, Barb Motenko, Beth Gomberg.
★★★★★Dustin HerlichIt's hard to describe. OSRUI campers and staff are a unique family. Ten stars. Except for the food. That's negative 20 stars. A well kept camp with loving staff and faculty. I love spending as much time there as possible. Year round.
★★★★★NicoleThe most awesome camp I have ever been to! The counselors are so kind, the food is good, activities were planned excellently, but most of all... I made new friends! Osrui is a great summer camp!
