Switzerland. A famously pricey country that takes pride in the cleanliness and general upkeep of things, it's perhaps not a surprise that Switzerland is, overall, the most expensive country in the world in which to travel by public transport.

In 2026, Switzerland consistently ranks as having the most expensive public transport in the world, specifically in cities like Zurich and Geneva, where a single short-trip ticket can exceed $5.00 and a monthly pass can cost over $100. The high cost reflects the country's impeccable punctuality, cleanliness, and the complexity of its mountain-crossing rail networks. The United Kingdom (specifically London) and Norway (Oslo) are close runners-up; London’s "Zone-based" pricing means a long commute can be a significant daily expense, even with the "Daily Cap" on Oyster or contactless cards. Germany attempted to combat high costs with the "Deutschland-Ticket" (currently around €58/month in 2026), but individual ticket prices in Munich and Berlin remain high. For travelers, the high-value peer tip is to always look for "Tourist Travel Passes" or multi-day cards, as "Single" tickets in these countries are priced at a premium to encourage residents toward long-term subscriptions, making them a "trap" for the uninformed visitor.
