We spent a wonderful 3 days in the Loretto unit of Fournie Lodge at Camp Ondessonk. We used our stay as a hub for hiking a number of Shawnee NF trails nearby. The unit has 2 bedrooms, bath and a large great room with gas fireplace. The kitchen is well appointed and there is an outdoor grill and fire pit. Beautiful touches throughout. Lovely views of the lake and amazing stargazing. It was a blesse... We spent a wonderful 3 days in the Loretto unit of Fournie Lodge at Camp Ondessonk.

2025: My child return - still just as fun and so well-kept. Food is still awful with very limited options. Yogurt and salad bar were empty when they got to the cafeteria each day. 2023:Extremely well kept and clean camp, lots of activities for kids, and plenty of space. The only feedback would be the need for better food. Edit: Meals-- D1 - Sloppy Joes/sweet potatoes and meatloaf/baked potato.... 2025: My child return - still just as fun and so well-kept.

(no additional veggies or sides - ground beef for 2 meals) D2 - Breakfast was fine but lunch was just a plate of ham (no cheese or turkey) with chips and granola bars (no veggies or fruits).

What a fun place for my kids! Wall Climbing, horseback riding, archery, food decently priced, face painting, all kinds of good, fun stuff! My only complaint is you feel pretty directionless. When you go to the wall climbing area, like other areas, there's no telling who came first for the staff and no doubt you will have those families that won't respect someone else being there before them and gi... What a fun place for my kids! Wall Climbing, horseback riding, archery, food decently priced, face painting, all kinds of good, fun stuff! My only complaint is you feel pretty directionless. When you go to the wall climbing area, like other areas, there's no telling who came first for the staff and no doubt you will have those families that won't respect someone else being there before them and giving them their due turn. It turns into a push and shove so you know your child is having fun too. It's a shame it is this way and why staff members should maybe come up with a way to make this easier on the families attending. Otherwise this place is pretty awesome.
