I think we can say it without exaggeration that many Hungarians are quite proud of the river views and the riverfront in Budapest (it is also part of the UNESCO world heritage). No wonder there are so many scenic sightseeing boat tours in Budapest.
What is less known is that there is a nice tram route right parallel with the river Danube, the riverfront route of Tram 2 / Streetcar number 2. This tram runs between the northern and the southern bridges, with many stops along the Danube. National Geographic has picked Streetcar 2 in Budapest among its top ten panoramic streetcar route list - in the world. While in the world list Tram 2 ranks as number 7, according to the travel and nature magazine of National Geographic, In Europe the humble Budapest tram 2 got number 1, the best! Congratulations to the 19th century urban designers of Budapest!
Number 1 tram route: 501 tram, Toronto Canada
Number 2 tram route: George Benson Waterfront Streetcar, Seattle, US (the service ceased a few years ago, but will be restored in another ten years or so)
Number 3 tram route: St. Charles Streetcar (yes, the original Streetcar named Desire!!), New Orleans, US
Budapest Number 2 Tram by the river Danube
You can easily get on it and go down to Lagymanyosi Bridge where the Palace of Arts and the Ludwig Museum can be found, get to the most famous Budapest Market Hall, by the Liberty Bridge, reach Vaci street from the tram stops at the Erzsebet Bridge or at Chain Bridge, and reach the nice green Margaret Island by getting off at Jaszai Mari Square stop. A streetcar named City Views, a streetcar named Budapest Desire. The tram cars are sort of heritage streetcars. Taking the tram 2 along the river is one of the top things to do in Budapest, and if you are travelling as a couple, take the panorama tram to enjoy the romantic Budapest.
By the way, tram 2 in Budapest at Christmas time gets all fancy.
