Hi- I will be travelling to Paris and would like to know the best way to get around the city on a budget.Thx?

The Paris subway is inexpensive and very clean.

the best would be the metro, the 2nd the buses... the metro is easier/cheaper but the buses allow you to see the city (but some metro stations are cool too)

Depend on how far u wanna travel in Paris. The metro has zones 1-8. The cheapest ticket you can get is either the individual trip ticket or the 1 wk pass of zones 1-3.

This is the RATP website (Paris Metro), check out their "Occassional Traveling" and "Travel Pass"

the metro or a bus

If you're staying toward the city center, most of the city is really accessible on foot. I was there for a week and only took the metro once and the train twice (to Versaille and the airport, too far for the metro).
If you are not up to a lot of walking though and you think you will be taking the metro often you can get a pass for it, which will cut down the cost.
I really enjoyed just wandering through the city on foot though, I think you find more interesting things that way.

The Metro is the quickest and cheapest way to get around Paris. Depending on how long you plan on being in Paris, I would suggest getting a Carte Orange, a weeklong Metro pass, also good for the bus. You'll need a 1x1 passport-style photo for the pass. You can purchase it at any ticket booth in the Metro. The price is around 15 Euros. It works Monday-Sunday and they stop selling it on the Wednesday of that week.

Your other option is to purchase a carnet of Metro tickets. You get 10 tickets for around 11 Euros. Individually, the Metro tickets are 1.40 Euros. Buying them individually isn't the best idea if you're on a budget.

I'd go with the Carte Orange.

Use the metro.
