Join us at Camp Ondessonk to experience the astronomical wonder of The Great North American Eclipse! We are so fortunate to be in the “Eclipse Crossroads of America,” where the center line of the 2017 eclipse passed over Camp, and now it will pass directly over us again on April 8, 2024!

Whether you stay with us for the entire weekend, or just for the 4 minutes and 9 seconds of totality, you won’t want to miss the breathtaking view that Camp Ondessonk offers.

About Camp Ondessonk

Camp is located on 983 acres of some of the most beautiful terrain in Southern Illinois for camping & hiking. We are uniquely situated adjacent to approximately 5,000 acres of uninterrupted Shawnee National Forest. A great destination for hiking, mountain biking, fishing or camping, our site is perfect for families or groups to spend the weekend in nature and sleep in a treehouse, pitch a tent, or for those who don’t wish to rough it, upgrade to a suite in our St. Noel Center.

Camp Ondessonk is a rustic and rugged campground with mostly open, non-climate controlled buildings. Camp is very spread out and the dining and activity areas may be as far as a mile from some of the units. No vehicles will be allowed inside the main area of camp due to the large number of guests expected. Expect to walk a lot over gravel roads and dirt trails while at Camp. The dining hall is modern and has air conditioning, but is located on a hill above most of the main area of Camp.



A “unit” is a cluster of 3-6 individual cabins that can accommodate 32-48 people. The units are rustic and there is NO ELECTRICITY. They are all unique in their own way. All units have fire pits, benches, picnic tables, a potable water spigot, an outhouse, and are within a short walk to a shower house. Each cabin includes no more than simply twin bunk beds with a mattress. Tent camping is allowed in all units, but only in previously impacted areas.

If anyone in your party has mobility issues, please contact the Office to arrange the best living situation for your while you are at Camp.

Below is a brief description of the various units:

Treehouses: The units of Goupil, Daniel, Lalemant, Garnier, Amantacha and Lalande are tucked away in the trees. These treehouse units feature A-frame roofs, three closed sides, and a labyrinth of connecting catwalks. Each cabin can accommodate up to eight people. Raganeau is unavailable to guests for this event.

Brebeuf Cabins: This unit resembles a treehouse, but the cabins sit on the ground. This unit is preferred if anyone in your party has mobility issues. Each cabin can accommodate up to eight people.

Chabanel Grotto: The coolest spot in Camp! This one-of-a-kind unit houses 16 people under a sandstone amphitheater and 16 people amongst two treehouses. Enjoy a waterfall if it rains!

Tekakwitha Cabins: This unit has three A-framed, fully enclosed, screened-in cabins, each holding 12 people. Uniquely located along a bluff line, its fire pit is underneath a cozy sandstone cave.

Aonnetta & Chiwatenhwa Cabins: Otherwise known as Monsignor Fournie Mini Camp Village, these units are co-located and share a common area, including a mini rope bridge, mini amphitheater and catwalks. Each unit has three 4-sided, fully enclosed cabins. Each cabin can accommodate 12 people.
PLEASE NOTE: These two units are designated as family-friendly units: quiet time begins at 10:00 pm, and alcohol consumption & smoking is prohibited at all times.

Check out photos of the various units on our website.


Camp Ondessonk’s St. Noel Center has nine private guest rooms. Each room includes private, comfortable hostel-style, climate-controlled lodging with a private bathroom, and free WiFi. Each room has one queen size bed (with linens), one full-sized bottom bunk (with mattress only-no linens), and several twin-sized bunk beds (with mattress only-no linens). Room capacity varies by room, but ranges from 6-11 people.

St. Noel is the only sleeping option with air conditioning. All guests have access to a shared meeting/dining space in the St. Noel basement, along with a kitchenette, barbeque grill, and outdoor firepit area.

Ahatsistari is one of two designated tent camping sites. This site is nestled in the woods, has an outhouse, fire pit, benches, picnic table, and shares a water spigot with the adjacent unit of Goupil.

Brebeuf Flats is a grassy, open area right off Camp road. It has its own fire pit and benches, and shares an outhouse and water spigot with adjacent units of Aonnetta and Chiwatenhwa.

Both areas are a short walk to a shower house.

Kane Lake, Pine Lake, Durbin’s Barn, Morgan’s Field & Pakentuck are unavailable for tent camping during this particular event. Sorry!

Tent camping is allowed in the units, but only in previously impacted areas.


We are not able to accommodate RV/camper parking during this event.
