My kids thought this camp was a lot of fun! They came home happy and exited to share all of there adventures at camp! They mentioned they felt very safe with the counselors and had a deep sense of belonging. They count down the days until they are back at camp and still make references every single day! This camp also gave them so much confidence in themselves me to step out of there comfort zones.

My kids love this camp. They had a wonderful time with the overnight and loved the food even after hearing it was bad; they thought it was yummy. The counselors were amazing and took great care of the kids. They made sure they had plenty of water and that they were saying hydrated throughout the day as well. They made many friends that even after camp they keep in touch with. The hikes that they went on and activities were challenging in a good way, and very fun. Overall this camp was great and my kids had a great time! My children were in week 5 and really enjoyed everything about the camp, especially that they got beads anytime they did anything well. I think it was a good system to keep kids in check but also make sure they had loads of fun. Even after camp they still talk about it all the time!

Our two kids (10 and 11 years old) just finished a one week Discovery camp. It was their first overnight camp experience. They loved it! There was lots of adventure including an overnight hike , white-water rafting and summiting a 13,000 foot peak. They made great friends and the loved the counselors. As parents we were taking a bit of a gamble coming from out of state but were immediately re-assured by the staff when we arrived and by the consistent updates (and pictures) about our kids while they were at camp.

I searched and researched camp options in CO for a long time! I came upon keystone and really wanted my girls (9 and almost 13) to experience overnight camp and all the joys outside and nature has to offer. The counselors were literally amazing humans! They were empathetic compassionate and Inclusive! I remember going to a faith based camp when I was younger and it was an awful experience but this camp was just so amazing! All of the campers were kind to my girls and although I was worried how they might do in the outdoors, doing activities they have never done, the counselors were there to ensure they had what they needed and made this an experience they will remember for a lifetime. I accidentally packed the wrong type of backpacking bag but they made sure they had an appropriate one. They did so many awesome activities in just 5 days, my girls were singing camp songs the entire way home, and had so many cool stories! My youngest cried when it was time to go home because she had so much fun and they're already talking about how ready they are to go back! It's an amazing place with an energetic amazing staff!!!!!! I wish I could send them more than just one week they'd probably go the whole summer if they could haha

My son has attended multiple camps at KSS including Discovery, Expedition and now the Counselor Assistant Program. He has learned how to make new friends, wilderness and perseverance skills and how to be a patient leader. We are so grateful for his experiences at KSS and how they have helped shape him into a responsible young outdoorsman.
