Given the size of the camp and the number of colleges present, I am not sure that there is another similar college camp. Yes, other colleges offer fine camps, but none run quite like this one. Some college camps have no other colleges there, some college camps have some other colleges there and run like this one does generally but on a smaller scale numbers wise. This camp has a lot of other colleges there, from all over the country and at all levels (DI, DII, DIII, JC, etc.) They do not have other Pac10 schools there, however (understandable). The schools alls are on the higher academic side also. Most coaches work the camp, some do not but instead come to sit and watch. Plus it is just a lot of fun for the kids - hard work, but fun. And there are a lot of kids there, too.
Beyond this camp, if you are interested in a school and that school has shown interest in you, by all means you should attend one (or more even) of their camps. It does many things for you - lets you see their facilities and play on their field, lets you get to know their coaches, and they you, lets you see the school generally, and the level of talent that the college may be recruiting (besides you), so you will know how you fit.
My two cents.
