Solage has become one of our very favorites in wine country. They renovated a handful of years back and did such a beautiful job. You can always expect incredible service, delicious food from both restaurants on site, and is an ideal warm weather pool-day resort. It's also very family-friendly! We also loved staying at Four Seasons. There are a little less of our favorites in Calistoga, so we usually spend most our time on properties when we stay up there.
