During the day, there is an excellent system of public transport in Krakow, covered by trams and buses (but remember, you can spend a lot of time in traffic jams!). The rush hours are mostly between 7AM-9AM and 3PM-5PM.
Buy tickets before you get on board. Ticket inspectors are fairly common and though the fines are not steep, they are not worth the hassle. Single, one-hour, daily, weekly, and monthly tickets are available and can be bought from news agents and kiosks. For single tickets, as soon as you get on, punch the ticket in the machine. A ticket must be punched or it is not valid. Daily tickets and one-hour tickets need to be punched the first time you get on, but do not do it again after that. Do not punch weekly and monthly tickets.
Ticket prices: single 2.50PLN, one-hour 3.10PLN, 24-hour 10.40PLN, 48-hour 18.80PLN, 72-hour 25PLN, 7-day 39PLN, family ticket (Sat-Sun only, unlimited daytime travelling) 10.40PLN, monthly pass 94PLN.
ISIC and Euro26 student holders that study outside Poland can use discount tickets, but not the full, 50% discount student tickets. They can use "gminny" fare, which means: single 1.35PLN, one-hour 1.65PLN, 24-hour 5.70PLN, 48-hour 11.50PLN, 72-hour 15.60PLN, 7-day 23.60PLN, monthly pass 41.70PLN.
When travelling to neighboring villages and to the airport you need an agglomeration ticket, that is just 0.10PLN more expensive. Keep in mind you need it even if you have any sort of valid time pass mentioned above (as they cover just the city area).
Single ticket prices are doubled during the night. Tram and bus stops show routes and most kiosks will be able to advise you on route numbers.
