The 8th annual Sierra Oro Farm Trail kicked off Saturday morning in many parts of Butte County. More than 30 wineries and farms are participating this year, which happens to be one of the largest turnouts. A ticket for the passport weekend includes a wine glass, and free entry into all farms and wineries, which have samples available at each site. The farm trail is the only weekend that all of the farms and wineries on the Sierra Oro Farm Trail map will be open. The farm trail will continue Sunday from 10 a.m. until 5 p.m. Tickets can be purchased for $25.
