Camp Ondessonk — Camp O Day 2025

Celebrating 66 summers of Camp Ondessonk with Camp O Day!

On June 28, we celebrate the moment the first campers walked through the Camp Ondessonk Gate in 1959 - and the beginning of a legacy that continues to shape lives today.To honor this incredible legacy, we’re inviting YOU to be part of the week of giving - a chance to give back to the place that has given so much to all of us.

Thank you for your interest in providing an in-kind gift! Whether you choose art supplies, maintenance tools, camping gear, or kitchen items, every purchase brings us closer to this goal - and directly supports the daily experience of our campers and staff.

Your participation is vital to the success of Camp O Day by helping maintain Camp Ondessonk’s programs. There is a wide range of supply needs to give you plenty of opportunities to get involved and show your support.
