Rain does not ruin Budapest; it redirects it. This is a city of grand interiors, covered markets and hot water, and a wet day pushes you towards the things that are genuinely best here anyway. This route keeps you under cover almost from breakfast to last drink.
Key facts
- Book the Parliament tour and any Opera House tour online in advance — both run in timed slots and sell out.
- The M1 metro line runs the length of Andrassy Avenue and connects several stops below; a 24-hour travel pass is the simplest ticket.
- The Great Market Hall is usually closed on Sundays. Check before routing your morning through it.
- Bring flip-flops and a towel for the baths, or budget for renting them.
9:30 – Start with the twentieth century
Begin at the House of Terror on Andrassy Avenue, which occupies the building used as headquarters by both the fascist Arrow Cross and the Communist secret police. It is a heavy, atmospheric hour and a half, and it explains a great deal of what you will see later. If you would rather start further back, the Hungarian National Museum covers the long arc instead.
