 “I cannot begin to express how lucky I feel to have been able to send my boys to CYO this Summer. What an incredible experience you created every single day across all age levels.  From the friendly greetings each morning as employees assisted with parking, to the friendships made, dance parties, nature experiences, friendly positive competition, beautiful artwork, to the fact that my boys have become extremely confident swimmers in a matter of 2 months.  I thank each and every one of you for making CYO the very best way to spend a Summer!  We will see you again next year! (And the next and the next and the next….) Christine Bischoff

“I have 6 year old twin boys that were in group 3 for the full summer.  This was our first summer in camp and we specifically chose the CYO based on the reputation.  My boys have been in day care since 5 months old (total of 3 centers) so we have had our share of child care experiences, the CYO program is exceptional.  We had heard excellent reviews and even at one time tried to get in the day care but there was a waiting list, which didn’t work out for us but is always a good sign.  As a first timer, the program did not disappoint.  From the initial Orientation to the last day of camp, everything was done top notch.  For various reason we had to communicate with carious CYO team members specifically Pat, Nurse Joyce, Counselor Michelle, and Kara DeBonis and EVERYONE could not have been more responsive, helpful, and professional.  My one son has a serious food and seasonal allergies and the staff took every precaution, going above and beyond, to ensure that he was safe.  I believe this Summer at camp reinforced and helped build my boys independence and confidence.” Jennifer Dromboski


In our 65th year of operation, our CYO Day Camp, which is located on a beautifully maintained 23-acre wooded site on Yardville-Allentown Road in Yardville, New Jersey, is better than ever! Each year our CYO Day Camp Staff strives to help each camper to enjoy a healthy, happy summer while developing in body, mind, and spirit. The CYO is proud that our Day Camp is accredited by the American Camp Association, a prestigious honor, and the gold seal in the camping industry.  The CYO Day Camp is accredited through the ACA until August 31, 2023.

Yardville 50th Anniversary of Day Camp (1958 - 2008)


The CYO Yardville Day Camp celebrated its 50th Anniversary during the Summer of 2008. The Day Camp, which opened on July 7, 1958, celebrated the anniversary with many fun and special activities and events for the campers all Summer long. On July 12, 2008, a special 50th Anniversary Picnic was held at the camp for former and current camp staff, families, and CYO friends.


Hundreds of people attended the picnic; many staff from the first year the camp operated, and they reminisced with old friends and former co-workers that they haven’t seen in years. Many guests toured the 23 acre campground and recalled fond memories of summers past.


The legendary CYO Camp founder and former Camp Director, the late Monsignor Leonard Toomey attended the picnic and visited with former staff members. Bishop Smith was in attendance as well, and blessed the new CYO Peace Garden, a reflection area in the camp that has been dedicated to all former CYO Day Camp staff members that have worked with the children here over the last 50 years.


The CYO is proud that over the last 50 years the Camp has gained the prestigious honor of being accredited by the American Camping Association. In addition, we had over an estimated 10,000 campers enjoy all we have to offer and over 1,200 staff members work here. We are looking forward to another 50 plus great years at the CYO Yardville Day Camp!

Yardville Counselor - In - Training (C.I.T.) Program


This Program is designed to train 14 and 15 year old CYO Day Camp graduates with the skills to become successful Junior and Senior Counselors. Eligible (former CYO Campers) and interested candidates should contact the CYO in February to receive an application packet. All candidates would need to fill out an application, write an essay on why they would like to be a Camp Counselor, submit their most recent report card proving passing grades, and interview with one of our full-time staff members.


A one time, $25.00 application fee is required. Second year, 15 year olds re-applying do not need to submit an essay for the second year, however, they still need to re-apply, submitting their report card, and possibly re-interviewing. The Program is very competitive, and spaces are limited, not guaranteed for being a Day Camp graduate.


Costs of the Program are as follows for 14 year olds: $100.00 for session 1 and $75.00 for sessions 2, 3, and 4. There is not cost for 15 year olds, and second year 15 year olds are paid $5.00 per hour. We do provide a complimentary lunch for each CIT; however, we do not provide transportation. Candidates can be chosen to work the entire Summer, or by the session (s). In conjunction with the CIT Program we also offer a 4 week Teen Travel Camp Program for 14 and 15 year olds.
