I'm not sure what you mean by "leading with how smart he is"? It might help me understand his experience at the outdoor camp a bit better if you could explain it - and please excuse me if I'm a little dense this morning!
Our EG science whiz ds always enjoyed outdoors camp in the summers. We didn't worry (there) re whether or not he was in with other EG kiddos, and it didn't seem to be an issue. He enjoyed the games etc and I think being outside gave him opportunities for his brain to think deeply in its own way. The camp he was at gave kids lots of opportunities to explore whatever they were learning about but there wasn't much guided learning - which was good, guided probably would have been boring at his level. For the more science-oriented camps, I'll be honest, we fudged his age to be older than he was to bump him up into higher-level camps a few times. Other times we just asked if he could attend with older kids and that usually worked out well... except ds had more fun with the same-age kids at his outdoors camps, gifted or not.
