An extremely well developed system of trams and buses operated by the wonderfully named ZTM providing a simple and fast way of getting around Katowice and its surrounding towns, now all part of the Silesian Metropolis. The tickets for the network are valid for both buses and trams. A three-zone system is used, of which Katowice is in zone-one and Chorzów in zone-two. Accordingly, a one-zone ticket is required for the former and a two-zone ticket for travelling between the two. A one-zone ticket costs 3.20zł and now also serves as a 20 min ticket allowing you to swap forms of transport (bus to tram and onto a different tram for instance) within that time period. A two-zone ticket costs 3.80zł and also serves as a 40 min ticket. There is also a three-zone/ 90 min ticket available for 4.80zł. A 14zł 24hr ticket allows travel across the entire metropolitan area, though it's hard to imagine getting your money's worth out of this without spending the whole day on the tram.
Almost all travel within Katowice and Chorzów can be accomplished using trams, most of which run through the new stops on the Rynek. Tram no.s 6, 11 and 19 run between the Rynek and Chorzów via Silesia Park and are the most useful trams for getting there and back. Tickets can be bought from any kiosk, or from bright yellow machines found at many tram stops around the city. Make sure you validate your ticket when entering the tram or bus. The penalty for riding without a validated ticket is 90zł (plus the price of the ticket) on the spot. (The normal price of the fine if you pay within 7 days is 125zł plus the price of the ticket.)
