Leave central Vienna and ride along the Danube toward Hasslau an der Donau, then continue east along riverside bike paths toward Slovakia. The scenery shifts between Roman traces, modern reconstructions, quiet riverbanks and borderland views. By afternoon, arrive in Bratislava, a compact capital with a layered identity shaped by its location between countries and cultures. Join your leader for an orientation walk, then keep the evening simple: dinner, rest and recovery.
