Google Fuge Camps. I'm looking at doing a summer mission trip that through organization, but it looks like they have summer camps too. They're mostly in the southeast part of the U.S., so I suppose it would all depend on where you're from. If that is too far away or sounds too expensive, try googling camps in your area and ask for lots of details, brochures, etc... plus see if you can visit and check it out for yourself. You also might want to try talking to other area youth pastors to see if they had suggestions for camps in your area.
