The Paris Mapguide displays the route numbers of city bus lines. Along with this I carry a little booklet detailing all of the bus routes--"Le Bus" by Indispensable.

another vote for Streetwise - you can't go wrong.

For me, it will be the Paris plan-net
by arrondissement because if I need a certain number on a long street, it tells me where it is between which rues.

Whitey, that is a public bus map of routes that pass by touristic sights.

If you want an actual tourist bus, ie. l'Opentour, then go here:

You can get the complete map, or click on each 'route' and get a closer-in map.

One more vote for STREETWISE PARIS. Has almost every street in central Paris, a handy metro map, taxi stands. Its super laminated finish withstands constant use and won't fall apart if it gets wet.

My other favorite is the HUGE Michelin Paris Plan, #58. You don't want to be unfolding it out on a street corner, but to see EVERY single street it can't be beat. Also, it covers quite a large area, more than just central Paris.

Both can be bought at major chain book stores. I got mine at Barnes & Noble.

I can't do without the plan de Paris per arrondisement. There are so many places that I wouldn't have easily found without it. The details are great. Also see cigalechanta's reason for having this one: I can always figure out where someplace is by street number.

I am going to try Robespierre's approach on this - on my next trip, I am going to try to navigate using my PPC and its loaded maps.

I have used Streetwise maps in the past and like them better than any others, but I am kind of "directionally challenged", and I need more help than a map alone can provide.

Does anyone besides Robespierre use PPC maps on trips?

I vote for <i>Le petit parisien - 3 plans par arrondissement</i> which includes a listing of museums in each arrondissements, post offices, market days and taxi stands. The first map is of the m&eacute;tro stops, the second is the more detailed street map, and the third is the bus map of the arrondissement.

Here's another vote for the Middleditch Mapguide, seen at <b>http://tinyurl.com/bhzal</b>. I just got back from my first trip to Paris and found it indispensible, as it includes ALL the streets, not just the main ones. It was small enough to tuck in my purse and I didn't have to worry about folding and unfolding it every time I needed to look something up, just flip to the right page. It has a comprehensive index of streets and includes a Metro map.

Yet another vote for Streetwise map. On my first trip, I had with me the Eyewitness Guide to Paris, which has a superb series of maps in the back with a street index, a little more comprehensive than the Streetwise Map.

Michelin Paris Pocket Atlas is compact yet detailed. Easy to carry and more discreet than a fold out map.

Since my first visit to Paris in 1958 I have depended on the free maps found in many hotels. My favorite is from Galeries Lafayette.

It hardly matters that I occasionally get lost. If I hadn't been heading in the wrond direction I'd never have chanced upon a little shop with stuffed toys where I found a delightful little caterpillar for my granddaughter.

I also liked Paris mapguide by Middleditch. I think that the spelling is right. I found it easy to use because it is a book form so you are folding and unfolding a big map trying to get your bearings. I probably paid $9 or so. Let me add that my husband and I found Paris very easy to get around. We stayed in the central area and things are laid out well once you get used to the Left and Right Bank.

I meant to say it is set up like a book and you don't have to fold and unfold a big map.
