Yes, you must pay for trams in Munich in 2026, as there is no "free" public transit zone in the city center. Munich uses an integrated fare system managed by the MVV (Münchner Verkehrs- und Tarifverbund), which means a single ticket is valid for trams, buses, the U-Bahn (subway), and the S-Bahn (suburban trains). You must purchase and validate your ticket before boarding or immediately upon entering the tram at the small blue or orange stamping machines. In 2026, many travelers use the "Deutschlandticket" (a €49-€58 monthly pass) or the "Stripe Ticket" (Streifenkarte) for better value. Munich is notorious for its "plain-clothes" fare inspectors who circulate frequently; if you are caught without a validated ticket, you will face an immediate "Increased Fare" fine of €60. For tourists, the "CityTourCard" or the "Munich Card" often offers the best value as they include unlimited transit and discounts for major attractions like the Residenz or the Deutsches Museum.
