|Subject: re: Yosemite National Park, California|
Yosemite is excellent in the winter for cross country skiing and snowshoeing. But you may find that there are few options outside of Yosemite Valley. The park is pretty much inaccessible now to all vehicles that do not have four wheel drive. In fact, the Yosemite website (http://www.nps.gov/yose) says Motorists should carry tire chains while visiting the park from November through March, and must have tire chains when entering an activated chain control area at any time of the year. This includes four wheel drive vehicles. Chain restrictions may be instituted at any time on any park road. You can get current road conditions at http://www.nps.gov/yose/roads.htm
Since you say that you love architecture, hiking and photography, why not head south to Monterey and Big Sur? You could easily spend four days along the central coast. The hiking is very good in the state parks near Big Sur. You can explore the historic missions in the area. If you don't mind driving a bit further south, you could visit San Simeon, the famous castle of William Randolph Hearst. And of course Highway 1 is spectacular. If you are lucky, you could even see grey whales on their migration. Sometimes they are visible from shore.
Hope you enjoy your trip!
