St Stephen's Basilica area
Start around Szent István tér and St Stephen's Basilica to anchor yourself on the Pest side. Keep this block on foot so Parliament and the riverbank feel like a natural walk north, not a metro hop.

Budapest, Hungary
A first-time Budapest route through Pest center and the Parliament riverside, Castle Hill with bastion views and at most one timed castle museum, then Heroes' Square, City Park and a single Széchenyi bath entry—without stacking paid tickets or ping-ponging across the Danube all day.
Day 1
Start around Szent István tér and St Stephen's Basilica to anchor yourself on the Pest side. Keep this block on foot so Parliament and the riverbank feel like a natural walk north, not a metro hop.
Drift to Kossuth Lajos tér for Parliament façades and the wide Danube promenade—exterior and riverside photos without committing to an interior tour today. Stay along the embankment so the Jewish Quarter is an easy evening extension.
Finish around Kazinczy utca and the ruin-bar lanes for local nightlife and casual dinner. No mandatory synagogue or museum ticket—keep the evening flexible for energy and crowds.
Day 2
Begin on Castle Hill with Fisherman's Bastion terraces and Buda Castle courtyards—prefer bastion views and castle grounds. If you want one paid interior, book a single timed slot for the castle history museum on the official site, not a second ticket in the same morning.
Loop past Matthias Church and the square below for Gothic tiles and skyline photos—exterior focus after a dense hill morning. Stay on the Buda side so you are not tram-hopping before the bridge walk.
Cross Széchenyi Chain Bridge at dusk and stroll the Pest embankment back toward your base. Keep dinner and timing flexible rather than adding another paid stop tonight.
Day 3
Open at Hősök tere and walk into City Park paths and the Vajdahunyad Castle exterior—strong architecture without a second museum morning before the baths.
Book Széchenyi entry on the official site for a midday or early-afternoon slot—one bath ticket for the whole day, not a morning soak plus a second spa later. Treat this as your main paid block on Day 3.
Wind down along Andrássy út past the Hungarian State Opera House façade and cafés. Keep the evening flexible for a show only if you already have tickets—no stacked performances after the bath block.
