If you visit Abiquiu, New Mexico to tour Georgia O’Keeffe’s home, which I highly recommend, you may wish to find the White Place (Plaza Blanca) before you drive back to Santa Fe. You just need to make a 30 minute detour off route US-84 onto a dirt road. You can get a map and directions when you have lunch at the Abiquiu Inn, which I also recommend.
You can’t beat the clear, dry air in New Mexico as well as the wide open spaces. Santa Fe and its environs are a wonderful destination for scenic beauty, art and delicious food.
