Day 1 — Danube axis: Parliament → Chain Bridge → Castle Hill
🚶 Start your morning at the Parliament building (Országház) on Kossuth Square: neo-Gothic, sharp spires, and bronze guards reflected in the waters of the Danube. Walk along the Danube Promenade to the Széchenyi Chain Bridge—the city’s first permanent bridge. The walk across (≈ 15–20 min) offers the best view: tram no. 2 glides along the water, and the Buda panorama looks like a postcard. Head up to Castle Hill either by funicular (2–3 min) or on foot via the switchback path (≈ 15–20 min). At the top: the Palace complex, bastions, multi-level courtyards, and views of the “parliament crown” on the Pest side. Plan 1–1.5 hours to take it in from the Fisherman’s Bastion terraces and around Matthias Church: sunset here gathers the whole city into a single panorama.
