Budapest is a big city and a bus Tour is a great way to discover it.
Multi-stop buses, also known as hop-on hop-off sightseeing buses, run through Pest and Buda. They make regular stops and you can choose to stay on or get off and then take the bus later. In addition, you can listen to an audio guide available in several languages.
Several bus companies offer this service in Budapest with many options over one or more days:
CITY TOUR Hop on/off
CITY SIGHTSEEING Hop on/off
BIG BUS TOURS Hop on/off
RiverRide FLOATING BUS
The RiverRide floating bus offers a 1.5-hour tour of the main sights of Pest and a dip in the Danube from this amphibious vehicle with a unique view of Parliament and Buda. –
