Tip: Make sure to use the Metro and not the RER when travelling within the city. The RER may look similar to the Metro, but uses a different train system that mainly serves areas outside the city. Metro stations are labelled with a large ‘M’, while RER stations are labelled ‘RER’. Metro tickets are also valid for buses.
There are also a number of companies offering hop on/hop off tourist buses that stop off at all the major sites.
