Here are some of the highlights from my first trip that I would recommend. I didn't spend much time around Taos, but their historical downtown has a lot of art shops, close to the Taos Pueblo.
Yuebo: One of the best SPAs I have been to, although I haven't been to much in the first place. Open till 10pm, so you can do star gazing in Jacuzzi which is very cool experience for me.
Yuebo: It's inside and associated with Ten Thousand Waves. It's on OpenTable. A bit pricy, but good food. And you can wear your Yukata to eat there inbetween your SPAs:D
Yuebo: Red rocks, close to home and studio tour in Abiquiu. There is another Georgia O'Keeffe's tour over there lol, showing the sighted scenes from her paintings around the sunset hour.
