Okay, I have a map called "Sequoia National Forest and Giant Sequoia National Monument," which is available at the ranger station. The ISBN is 978159351509-6 and it was printed in 2011. The place where we camped was east of the Grant Grove Visitor Center and the King Canyon Overlook, off of General's Highway. We were close to Horse Camp and Buck Rock. There is a lot of dispersed camping available in that area and it's beautiful. Some areas are a little more crowded than others. But you should be able to find lots of dispersed camping in that area, even on Labor Day weekend and even a more secluded site. For the Buck Rock Lookout open house, check out their flyer at: http://www.buckrock.org/Labor%20Day%...0pdf%20(1).pdf
. Good luck and have a great time!
