★★★★★Regan DoweCamp 603 is the preeminent summer camp in NH and for good reason! Joe Rider has been developing his vision for fun filled camp experiences for many years and draws on his experience as an educator when devising activities and experiences for campers. He has been able to recruit an outstanding group of counselors that the campers easily connect with. Camp 603 does an amazing job of exposing campers to amazing outdoor pursuits that has many campers signing up for multiple weeks over a single summer and returning year after year. You won’t regret a fun filled week with Camp 603 !!!
★★★★★Sarah SartorelliThis camp is so awesome! Each day is packed full with fun. The counselors are outgoing, welcoming and friendly! So much to say, my kids love Camp603. Every year they’ve tried something new, which is so exciting for them! From singing in the van, dancing on the beach, and making friendship bracelets to tubing on the boat, cooking dinner over a campfire and exploring NH. It’s the right amount of adventure for my kids. I highly recommend!!!
★★★★★Robin RaderCamp 603 is hands down one of the best camps my daughter (age 12) has attended! It is a camp like no other that will have your child wanting to go back each year. Joe Rider and his staff make every moment enjoyable! From the van rides to and from the location to the overnight sleeping under the stars! Each day is filled with different adventures and I loved hearing the stories from my daughter about her counselors, the boating/tubing excitement and even her hiking trips. This camp promotes independence in addition to team work and creating life long memories.
★★★★★Cindy AndersonBoth my children attended the 603 camp, 2 years in a row. My son did 2 different weeks one year. They had a blast, it is not your typical camp. I love the hiking, boating and beach. It is what summer is all about! Joe Rider does a great job!
★★★★★Denise GridleyOur daughter participated in Camp 603 for 3 years in a row and she LOVED it! Mr.Rider and his staff challenged the campers to go out of their comfort zone to embrace the beauty of NH and try new things. Each day after camp our daughter was SO excited to share the exciting adventures of that day! She is in high school now and still talks about the fond memories that she made at Camp 603. Thank you Mr.Rider and staff for providing this extraordinary opportunity for our daughter!
