Hohenschwangau Castle It's fairly easy to walk to this castle.

This romantic king loved the legend of the star-crossed lovers, "Tristan and Isolde," adored the opera and supported the composer Wagner, and tucked fairy tale castles that were more whimsy than substance into clefts in the Alps.  But the people of Bavaria accused King Ludwig II of insanity, and, according to our guide, "He went for a walk with the psychiatrist sent to evaluate him and both men were found dead in the lake of mysterious circumstances later that day.  The next week, his castles were opened to the public as museums."
