A trip to Vienna is not complete without fully exploring its outskirts - woods included. The guided tour takes you from the city of Vienna through the enchanting Vienna Woods, the memorial chapel of Mayerling, the Abbey Heiligenkreuz and the Seegrotte Hinterbrühl, all in half a day. Opt for a pick up with your hotel or meet up with them at the Vienna State Opera, then head off to the southern part of the Vienna Woods. Take in the panoramic views of the former Roman spa town of Baden and Helen's valley as you make your way to the memorial chapel of Mayerling. The chapel, built on the former imperial hunting lodge of Mayerling, is famous for the tragedy that befell the lodge in 1889. Learn about the fateful events as your guide takes you around the chapel and showroom. Next up, you'll visit Abbey Heiligenkreuz, where you can find the medieval cloister and the burial place of the former Babenberger rulers. The tour ends with a trip to Europe's biggest underground lake, Seegrotte Hinterbrühl, where the Germans built an underground aircraft factory in World War II. After half a day of exploring the majestic and enchanting Vienna Woods, return to the city proper to explore the rest of Vienna.
