Hi Thiengairrue73
1) Yes, but if you make only a single trip from Annecy to Geneva, it could be cheaper to buy two separate tickets:
— Annecy - Geneva CHF 19.20
— Day pass for Geneva Zone 10 CHF 10.00
If you return to Annecy on the same day, you can buy a Léman Pass Day Pass for CHF 38.30. You must also make the return trip with the train.
2) Yes, the passes with zone 10 include the tram or bus to Carouge.
3) For Annecy I don’t know, but I think that it is not possible. Please note that if you want use buses in Annecy, the Léman Pass should also include the zone 380.
In Geneva, you can use only the “Mouettes Genevoises”:
