Travel south on Hwy 280 - considered the most beautiful freeway in the US - to the Winchester Mystery House. In 1884, the Winchester rifle heiress Sarah Winchester began work on the 160 room Victorian. For 38 years she kept carpenters working 24 hours a day non-stop. The Mansion is filled with so many unexplained oddities, that it has come to be known as the 'Winchester Mystery House'. See 'The gun that won the West' in the 'Fire Arms Museum', one of the largest Winchester rifle collections on the West Coast. Also see the "Antique Products Museum", which has a rare collection of antique products once manufactured by the Winchester Products Company. There will be a guided tour of the Mansion, and time to see the beautiful gardens and museums before returning to San Francisco.
