Winchester Mystery House
If you want an unusual tourist attraction while you're here, spend a day at the Winchester Mystery House. It's a crazy, sprawling mansion with stairs that lead nowhere, doors that lead to open space and windows that look out onto walls. Designed by the widow of the Winchester rifle magnate in a series of seances, it's a fascinating obsession made real.
