Western Us Biking Suggestions

Hi Ladies,
My DH and I are going to get away for three days in two weeks and are unsure where to go. We live in SoCal and don't want anything local. We were thinking about Las Vegas and maybe riding out to Red Rock Canyon, but that looks like the only ride in the area. Any ideas? Anything in AZ, CA, OR, NV, WA or UT would be appreciated. We will be staying in a hotel or B&B no bike camping as we will be camping with the kids earlier in the week for Spring Break.
Thank You!!

Napa or Marin are lovely and lots of good riding.
