Keep in mind that much of Pole Canyon Rd is a dirt road, and in the winter months you'll likely have trouble getting a regular vehicle up there, but you could easily drive a snowmobile or snowshoe/cross-country ski up here if you were so inclined. A solid 4x4 vehicle might get the job done too IF the snow isn't too deep.
