Andrássy út starts a short distance northeast of Deák Ferenc tér and stretches for 2.5km, ending at Heroes’ Sq (Hősök tere) and the sprawling City Park (Városliget). On Unesco's World Heritage list, it is a tree-lined parade of knock-out architecture and is best enjoyed as a long stroll from the Opera House out to the park.
On the way, don't miss the New Theatre , Művész Kávéház , the House of Terror and the beautiful Kodály körönd, a square (or more accurately a circus) just over halfway along.
