No, trams in Brussels are not free for the general public. They are operated by STIB/MIVB, and you must have a valid ticket or a validated MOBIB card to ride. As of 2026, a single-trip ticket valid for one hour costs around €2.50 to €3.00 if purchased via contactless payment or a ticket machine. However, there are exceptions: children under the age of 6 travel for free when accompanied by a paying adult. Additionally, the "Brussels Card" for tourists includes unlimited public transport for a set period (24, 48, or 72 hours), which can make the rides feel free once the initial card cost is covered. It is important to note that fare evasion is taken seriously, and plainclothes inspectors frequently board trams to check for validated tickets. If you are looking for free transport in Belgium, the city of Hasselt famously offered free buses for years, but in the capital city of Brussels, you should always expect to pay for your journey on the extensive tram, bus, and metro network.
