this was an incredible place. It was covered in snow when we went and we had to hire chains before entering the national park. Luckily we had a 4x4 so we didn't have to use them but you still need to carry them. You can rent them in three rivers for $40. A must!! we stayed up at wukasachi lodge for the night and waking up to snow outside was incredible...coming from an Australian that has only seen snow a few times. Nice easy walk on the general Sherman trail. Would have helped if we had snow shoes/boots.
