we will be driving from yosemite to las vegas in second week of july and would like to stop at sequoia / kings canyon and see the general sherman tree and the grant tree as well . assuming i make it to kings canyon around 1 in the afternoon can i see both of these icon trees within say 4 hours so i can make it to the vegas halfway point early enough to shack up for a night ? and good suggestions on where to stay between this park and vegas to do some early morning sightseeing before heading on to vegas ???
