Our 'go to' campground in Ketchum, Idaho (Sun Valley) is Boundary.  What we like so much about it is the cleanliness and the 'space' you feel, even though you are around others.  We also like that there are only 10 campsites, and that it's VERY close to The Village Station, where they have the best happy hour scratch margaritas around!  The bike path has recently been extended, and will continue, so that you can bike into town, directly from the campground.  Finally, we both work from home, and this campground allows us to do this very easily, yet still remain in nature!
