Castles & Capitals of the Balkans (Serbia, Hungary, Romania & Bulgaria)

Belgrade → Sofia 14 days Up to 15

About this trip

Four countries in two weeks, tracing a route through Serbia, Hungary, Romania and Bulgaria that takes in capital cities, medieval towns and the castles of Transylvania along the way.

You travel with a small group and a guide throughout, with hotels, transport and entrance fees sorted, so the days are about taking in the places rather than working out logistics.

It's a broad sweep of Central and Eastern Europe — Belgrade's riverside setting, Budapest's bridges and views, Bucharest's grand boulevards, and Bulgaria's older, quieter villages and cities.

What you'll do

  • See Belgrade at the meeting point of the Sava and Danube rivers
  • Take in Budapest's bridges and skyline views
  • Explore Transylvania's castles and small towns
  • Walk Bucharest's boulevards, known for their architecture
  • Visit medieval cities and villages in Bulgaria
Good to know
  • Covers four countries in 14 days, so expect regular moves between bases
  • Guided throughout, with hotels, transport and entrance fees included
  • Suits those who want a broad overview rather than lingering long in one place
