This 10-day tour will leave you wondering why you waited to explore Europe's roads less travelled. Ride the rails from Budapest to Sofia and experience Eastern Europe’s charm firsthand. Soak in a thermal bath in Budapest or opt to visit Buda Castle, Hungary’s royal palace. Discover Romania’s countryside while visiting Sighișoara or marvel at the baroque architecture of Brasov. (Better yet, enjoy the contrast by seeing them both.) You'll also have time to sample Bulgarian cuisine that'll give you the energy you need to cycle your way through Veliko Tarnovo, one of the oldest cities in the world.
