Budapest pairs Buda's hilltop Castle Quarter and the Fisherman's Bastion with Pest's Parliament riverfront, the thermal Széchenyi and Gellért baths, and the ruin pubs of Szimpla Kert in the old Jewish quarter.
Spring blooms across Margaret Island, Sziget Festival the second week of August aside, and the Danube cruise season opening with Parliament views haze-free.
Sziget Festival the country's biggest music event on Hajógyári Island, hits 32°C, and the thermal baths packed but the river cruises run dawn-to-late-evening.
Budapest Wine Festival mid-September fills the Castle Quarter, Café Budapest contemporary arts festival in early October, and Margaret Island chestnuts turning.
Christmas market at Vörösmarty Square considered Europe's most photogenic, Széchenyi and Gellért bath culture at peak, and the Buda Castle in winter snow striking.
