Facility Rental and Recreational Programming
When we are not hosting a special weekend event, Camp Ondessonk functions like a public campground and event venue. Our site is perfect for families or groups to spend the weekend in nature and enjoy our 983 acres and adjacent Shawnee National Forest. Sleep in a treehouse, pitch a tent, or for those who don’t wish to rough it, rent a suite in St. Noel. Larger groups can arrange for meals and programs, as well. We host families, scout troops, and church groups, but also have capacity for up to 400 people. Click here for more information about great things to do at Camp on your own during the non-summer months. Larger groups wanting meals and programs should contact Camp first about availability several months in advance – especially during the busier spring and fall months. Call (618) 695-2489 or email greg.santen@ondessonk.com

LODGING:
Camp Ondessonk’s Signature Treehouses
One of the highlights of an Ondessonk visit, our 3-sided treehouse cabin units take full advantage of their natural surroundings. They are intentionally designed and located to maximize visitors’ experience of tranquility and inspiration of Nature. Some are on the ground for ease of access, one is built under shelter bluff with its own waterfall, and others are walled in for a bit more security. Whichever unit you choose, you will be immersed by the natural world in a unique setting. Most cabin units have 5-6 cabins and sleep around 40 guests. Click here to see more photos. All cabin units have fire pits, benches, picnic table, water spigot, outhouse, and are close to a showerhouse.
