Residential (overnight) marine-biology summer camp at Toyon Bay on Catalina Island, about 2.5 miles from Avalon, for ages 8-17. One-week and 2.5-week sessions combine ocean adventure and hands-on marine science - kayaking, scuba diving and marine-biology labs - with traditional camp evenings and campfires; campers stay in dorm-style housing with a waterfront dive deck.

★★★★★Andrew Smithfile:///var/mobile/Library/SMS/Attachments/ef/15/12BB48ED-9F57-44CE-870B-93A9202C7218/IMG_3543.heic My son Hunter absolutely loves Catalina Sea Camp. From the time summer break starts, all he talks about is, “Dad, when am I going to camp?” After this last camp session, I saw so much maturity and growth in my son because of this camp. He told me all about his snorkeling experience and how he saw leopard sharks, Garibaldi, shovelnose guitarfish, kelp bass, and so much more. He also loved rock climbing, making new friends, and all the other activities, but snorkeling really stood out to him. It is well worth the money. I highly recommend Catalina Sea Camp. Sincerely Hunter Father Andrew Smith

★★★★★Bridget AThis was my daughter’s first time at sea camp and first time being away more than a week. She did three weeks at Toyon Bay and cannot wait to go back next year. She particularly liked the art class where she snorkeled at different locations and then made art of what she saw. She got homesick but the director and counselors were so on it. They called me and checked in on her and by day 4 she didn’t want to leave. I want to make a special note about how the camp handled the massive IT outage on pickup day. Just brilliant. They stayed with the kids who were flying alone all the way to their gate and had airport hotels setup for kids whose flights were canceled. I really appreciate how organized and positive they were throughout camp but especially with such an unexpected emergency. We will definitely be back!
