Powered by GoogleI have three kids and all of them have been to Camp Keystone as their fifth grade culmination special. I have accompanied each of them each time and the they all had unlimited fun as well as pop corns, ice cream, and soda, ok, so did I and we all had no regrets. Lunch was served on time with fresh vege, burgers, hotdogs and side dishes as well as fresh cut fruit. Happiness with zero interruptions. Camp activities include swimming, water slide, jump house, tube sliding, and sports. Kids are busy! There are many trees so camp grounds are covered with shades which make hot summer days comfortable. I know there are other services such as zipline but our school didn’t raise enough funds to cover these activities this year. Not a problem since the activities they are able to do kept everybody occupied. My oldest kid did the horse riding camp in summer and really enjoyed it. These days we are finding it hard to sponsor such activities but for those who are able to, I recommend you to sign your kids up if they are interested. My kids found it to be safe and fulfilling.
We LOVE camp Keystone. Our family has been coming here for the last 4 years. We really missed last year due to COVID and were so happy that camp was back this Summer. My 3 kids love it here, it's like home away from home. The staff and counselors are super engaged and really go the extra mile to make sure the experience is memorable.
This is our 5 year olds first time at camp. I was a little hesitant about sending him at such a young age but actually he’s not the youngest. There are campers in Junior Camp with him this summer that are 3 years old! My son has completed his first week at camp and loves it. I would without a doubt send my daughter when she’s 3 after the great time I see my son having. I feel my son is very safe. I feel the counselors and directors want to give the kids a safe and great experience just as they likely had themselves as kids. I had every concern a parent would have about sending a 5 year old to camp without anyone he knows, but I’ll tell you what changed my mind. My husband and I decided late in the summer to send our son to camp before he starts kindergarten to give him some more social experience considering covid has kept his preschool experience quite limiting this last year and a half. The owner kindly met us at the camp one day even though tours had already happened on previous days we missed. He talked to us and gave us a tour of the grounds. After leaving we felt extremely confident this was the camp for our child. I looked into other camps but Camp Keystone had beautiful grounds, an owner that is extremely competent and passionate about his camp. He wants the kids to just be kids, especially after such a difficult year. I made a call to Cali Camp prior to making a final decision about where to send my son. They told me I would not be able to come for a tour unless I signed up for camp first. I felt very rushed on the phone as well. They did not make me feel valued. When I called Camp Keystone to inquire about a tour, the woman I spoke to took her time to talk to me. She didn’t rush to end the conversation. She told me about her personal experience sending her child to camp at a young age and how much the camp meant to her family leading to her eventual employment at the camp. I’m glad I signed up my son for 2 weeks. Summer camp was a big part of my husband’s childhood and he is happy we found a place for our son to start his camp experience. I wish my parents had sent me to a camp as awesome as this one! I expect my son and eventually my daughter will have great summer memories at Camp Keystone!
Our 5 year old went for spring break and then back for almost 2 months of summer camp. She loves swimming and all the fun outdoor activities. She also loved her camp counselors. As parents; We loved their extended care program, the office staff was very kind and accommodating. I do wish there was a bus option for us coming from Woodland Hills. Overall I’d say the Camp Keystone experience is like a big carnival. Great fun for kids. maybe a little too much emphasis on sugar (my daughter said there was only sugary food available in the snack shack, I haven’t verified that for myself) We’ll definitely go back
My kids LOVE Camp Keystone! They've attended for the past 5-years, and even as they grow, they enjoy new discoveries, new friends, and ALWAYS have great relationships with their counselors, who they tend to talk about for months after camp ends. We look forward to it year after year and feel that the summer camp programming offered are stand-out experiences making memories for kids for years to come. Thank you to their hard working staff!
