Yes unlimited options and for all skill levels. Very active dual sport community down there. I fly in from Boston and do a couple weeks at a time. I like winter, but also Sep/Oct when I can get up into southern Utah and ride the red rock trails.
Plenty of people from this site have invited me to tag along and I have. I just have to make sure they know I am not a hardcore single track rider. Still, they drug me down something called Turkey Creek.

9 water crossings with rock gardens going in and climbing out! I didn't realize a motorcycle could roll that stuff!
I wasn't happy at the time, but I made it without too much drama so it feels good now.
You'll love it down there. I rode my 250 on the CDR and then left it at a friends house in Phoenix area. I may buy a condo down there eventually. I just have to make sure I'd use it. This past spring I replaced my KTM 950 with a spanking new 690R. I'll keep that as my main ride at home. LOVE that bike!
Have fun and post some RR's in the Day Trippin' section.
