I am considering travelling to Sequoia and Kings Canyon in January and I have a number of concerns.
A. Which parts of the park will not be accessible then? Will I be able to see General Sherman tree and Grant tree?
B. Are the roads into the park very bad that time of year? Do I need tire chains with a 4WD car? Do rental companies prohibit driving in these areas even with 4WD?
C. Lastly, is it overall worth seeing in the winter or should I hold off for another time? I live in NY, and if the parks are not worth visiting in January, I'll hold off on California until a better season.
