if you can get in :)
Madison is very shady, set inside a forest of lodgepole pines. water and dump
Bridge Bay has a large open area on a slope, and a large area set in trees. water and dump
Mammoth is set on a slope with great views, etc and isn't hard to navigate. water and dump
Norris campground is small and pretty with good shade.
we like Bridge Bay best because we like being close to Fishing Bridge visitor center and Lake Lodge's dining room... decent food for decent price. and because it is kind of centrally located.
