Yes, you can travel to Basel using the Deutschlandticket (49-euro ticket), but with specific conditions. The ticket is valid for travel to Basel Badischer Bahnhof (the German-operated station in the northern part of the city) because this station is treated as part of the German rail network for tariff purposes. You can take any regional train (RE, RB, S-Bahn) from within Germany to this station without paying extra. However, the ticket is not valid for ICE, IC, or EC long-distance trains, so you must plan your route using regional transport. If you wish to travel further into the city to Basel SBB (the main Swiss station) or use Basel's local trams and buses, you would typically need a separate Swiss ticket, although some regional German tickets have local agreements that allow travel to the city center. In 2026, the 49-euro ticket remains one of the best ways to reach the Swiss border economically, as long as you are comfortable with the slower pace of regional trains and ensure you stay within the "Badischer Bahnhof" boundary for the ticket's full coverage.
