Unless I'm mistaken, the SUDAZUR Explore Pass in the French Riviera is good for "Unlimited access to trains, streetcars and buses in the 06 department and Monaco". The pass can be bought for 1, 3 or 7 days (for 35€, 50€, or 80€, respectively, plus 2€ for the card). Seems to me that for many visitors this is the best value and by far the most convenient means to pay for and validate all regional transportation.
However, unless I'm again mistaken, I can't find this transportation option mentioned anywhere in the brand new march 2026 Provence and French Riviera guidebook.
If I'm wrong about any of the above, please set me straight! If I'm right, what's the proper way to notify the Rick Steves Team to get this info into the online guidebook updates?
The only weird aspect of this is that as best I can tell, one cannot buy the pass from a machine at the Nice Airport, but must instead take the tram one stop (free), and buy the pass from a machine there. I guess that's to stay consistent with the principle that nothing in France can be completely simple and logical. :)
