Enjoy a scenic excursion through the Roman city of Baden and the dreamy Helenental Valley. Visit Heiligenkreuz Abbey and the hunting lodge of Mayerling. In a forested highland area of Vienna Woods, explore the Seegrotte (sea cave), a cave system hiding the largest subterranean lake in Europe.
Pass through the Roman city of Baden en route to the former Mayerling hunting lodge. The lodge is now a commemorative chapel, remembering the deaths of Crown Prince Rudolph and Baronesse Vetsera, both of whom died tragically during the infamous Mayerling Incident of 1889.
Marvel at an intricate medieval cloister in the Cistercian Abbey of Heiligenkreuz before continuing on to the Seegrotte. Here you jump on board a boat and delve into an underground cave system and across an underground lake—Europe's largest. Sit back and relax as you head back on a comfortable journey to Vienna.
