Sequoia and Kings Canyon campground recomaditions

I would recommend either Dorst or Azalea -- large sites in both places. Don't try to come up through Three Rivers -- come in through the north. Dorst is more centrally located. Great hike to Muir Grove leaves right from the campground.

I would avoid Lodgepole with that big of a group -- too tight. If Dorst is booked up, maybe try Stony Creek, nearby.
