Andrássy út, listed as a Unesco World Heritage Site, starts a short distance north of Deák Ferenc tér and stretches for 2.5km to the northeast, ending at Hősök tere and Városliget, Pest's sprawling 'City Park'. Andrássy út is such a pretty boulevard and there's so much to enjoy en route that the best way to see it is on foot, though the M1 metro runs beneath Andrássy út from Deák Ferenc tér as far as the City Park if you tire out.
