Roads:
Budapest is the most important Hungarian road terminus; all the major highways end there. Budapest is also a major railway terminus.
Ring road M0 around Budapest was recently completed and allows people to go around Budapest from East to West and from North to South, however there is no way from West to North - you must go around to the South.

Public transport:
Budapest public transport is provided by BKV,[57] the company operates buses, trolleybuses, trams, suburban railway lines, the metro, a boat service, a cogwheel railway, a funicular, and a chairlift, called Libego.
Budapest's tram network is extensive, and reliable despite poor track infrastructure and an ageing fleet. Routes 4 and 6 combined form the busiest traditional city tram line in the world, with the world's longest passenger trams (54-metre (177 ft) long Siemens Combino) running at 60 to 90 second intervals at peak time and 3-4 minutes off-peak and usually packed with people.
Day services operate from 4:30 a.m. until 11:30 p.m. each day. Night traffic (a reduced overnight service) has a reputation for being excellent.
There are three metro lines and a fourth is currently under construction. The Yellow line, built in 1896, is one of the oldest subway lines in the world, following London Underground and the Istanbul Metro that were built respectively in 1863 and 1875.

Railways.
Main articles: MÁV and HÉV
Hungarian main-line railways are operated by MÁV. There are three main railway termini in Budapest, Keleti (eastbound), Nyugati (westbound), and Déli (southbound), operating both domestic and international rail services. Budapest was one of the main stops of the Orient Express until 2001, when the service was cut back to Paris-Vienna. There is also a suburban rail service in and around Budapest, operated under the name HÉV.

Waterways
The river Danube flows through Budapest on its way to the Black Sea. The river is easily navigable and so Budapest has historically been a major commercial port (at Csepel). In the summer months a scheduled hydrofoil service operates up the Danube to Vienna.
