Camp Onas is an overnight camp in Ottsville, Pennsylvania for children ages 8-13, founded in 1922 by the Religious Society of Friends and owned and operated by the Friends Camp Association of Pennsylvania. Daily activity periods include arts and crafts, sports, swimming, performing arts and limited-capacity options such as archery, canoeing and a high and low ropes course, with campers choosing most of their own activities; optional add-ons include a three-day Appalachian Trail backpacking trip for campers 12 and older and a day canoe trip on the Delaware River. The camp offers one one-week session and three two-week sessions, with check-in from 2-4pm on the start date and check-out from 10am to noon on the end date; registration runs through CampBrain, opening November 1 for returning families and November 15 for everyone. Camp is rooted in Quaker values, is technology-free, sleeps campers in open-air platform bunks, serves vegetarian, vegan and gluten-free options at every meal, and offers need-based financial aid plus a $75 sibling discount.

★★★★★wolff mprobably the best place on earth. i’ve attended as a camper for 7 years and some of the best experiences of my life came from this place. i’ve made lifelong friends here. everything is so fun and i don’t think i’m ever as happy as i am when i'm at camp. the counselors were always the nicest people ever, the activities were fun and interesting, and the food is sooo good. i highly recommend sending your kid here, you wont regret it. i attached a photo i took on my polaroid of the texas building+white house. it’s beautiful there.
★★★★★N CThe best camp. My 10yr old son just did a two week session at Camp Onas. He had a blast. Every one was so nice. This was my son's first time doing sleep away camp, I was nervous,but it was all for nothing. Holly was amazing,and so was all the counselors. 2019 summer he already said he's going for two sessions.
