1. Sonoma County, CA
It’s easy to swoon over Sonoma. While wine tasting is the main attraction, there's so much more to this sprawling California county. Get pampered at world-class spas (head to Dawn Ranch for an oasis set among the redwoods); dine your heart out at restaurants rooted in seasonal California fare (splurge on a multicourse tasting menu at the ultra-luxe Cyrus Restaurant); or head to the coast to take in stunning ocean views at boutique hotels like Nick's Cove or Timber Cove (grab a bite at their waterfront restaurants or stay the night).
