Does anyone know how visitor tram passes work? I know if you stay overnight in Basel and you are¨'automatically entitled to a Mobility Card, giving free tram and bus travel throughout the city; the card is available from your hotel at check-in.'
What if you do not stay in a hotel? My sister will be visiting me in Basel in February and i am looking for the cheapest option for her. Also, are there discounted visitor train tickets (like thr half tax residents can get)? Thanks in advance!!!

What I've done when people have visited is bought one of the 7-day passes from the tourist office or the tram company's office on Barfusserplatz.

They're 30ish francs, as I recall. The visitor stamps it on the first day of use then it's good for 7 days from that first stamp.

I don't know about train tickets, though. Hope the tram thing helps.

Edit - managed to find this: Travel Passes for Visitors - link to previous thread on here that I put in my favourites so it must be useful.

When I visit Basel I buy a card that you punch each time you get on a tram, I think it's a 10 journey one, don't think it goes by date. It's very convenient. Can't recall the cost but not too bad. I even got a bit of a discount last time as I had a Halb-Tax card for my other travel! Could be others, experts will advise!

A halb-tax will allow you to buy the mehrfarhtkarte for child prices. If you don't have a halb-tax, you get 6 journeys for the price of 5 (12 for 10). Make sure it covers enough zones.

You can also get day cards covering zones 10, 11 and 13 - that includes the airport, but excludes Pratteln, and other outlying regions. You can get 1-7 days cards covering the whole of the TNW region. Prices here. Note, you can't use halb-tax with these cards.

You can buy them at most ticket machines.
