Lots of opportunities in Arizona and Southern California. Just be aware that you must check the current weather forecast, since the November scene can be highly variable. A lot of trips involve going to higher altitudes for at least part of the journey. During November you might encounter snow on the ground, though it is not likely.

If you want really warm temps, consider forays in Anza Borrego, the Sierra Pinacate (Mexico), and Organ Pipe Cactus and nearby areas.

If you want something really different, inquire at Channel Islands National Park about backpacking on Santa Rosaa Island - probably not a possibility this year, but 2012 will be a whole new ball game.
