Summer Programs for Advanced Kids

My 11 year old is taking college precalculus this semester and will likely take Calculus I next semester.  She is mostly interested in Cosmology as a career and I want to find a summer program that will encourage that interest in the topic; entertainment is more important than challenging her intellect.  She is already pushing herself hard enough during the school year, so I want her to see the summer camp as a reward for working hard this year, but I also want her to see the possibilities of a future in science.  Most of the science camps for kids her age are below her level so she is just bored.  I'm wondering if anyone on here has found a really high class summer camp for gifted kids.  I don't want to say money is no object, but I'd be interested in any programs that people know about. 

Thanks.
