What good transit means
Frequency (under 4 minutes peak), reliability (98%+ on time), integration (single ticket buses + metro + trams), 24-hour or extended service, intuitive wayfinding for visitors. Below: cities that excel.
Vienna
Vienna Wiener Linien — Europe's most reliable metro by independent rankings. Single-fare ticket €2.40 covers all modes. Annual pass €365 ("a euro a day"). 24/5 service Friday-Saturday nights. Innere Stadt base.
Helsinki
Helsinki HSL — fully integrated tram/metro/bus/ferry with single fare. €3.50 single, €11/day pass. Real-time arrivals universally accurate. Plus Tampere/Turku also excellent at smaller scale.
Zurich
Zurich Verkehrsbetriebe Zürich (VBZ) — Swiss-precision running. Tram + bus + Forchbahn integrated. Day pass CHF 9. Boats on Lake Zurich included.
Copenhagen
Copenhagen Metro fully driverless 24/7 plus bus + S-train + Cityringen ring line. DKK 24 single, DKK 80 city day pass. Strong cycle infrastructure adjacent.
Madrid
Madrid Metro Madrid — 13 lines, 302km (Europe's third-largest), modern stations, AC. €1.50–2 single. Strong frequency (under 5 min). Cleaner than Paris Metro by far.
London
London Underground (Tube) — historical icon but cramped, hot in summer, occasional delays. Contactless tap-and-go highly modern. Night Tube weekends (Fri-Sat). £6.50/day cap.
Berlin
Berlin S-Bahn + U-Bahn + tram + bus integrated. €3.50 single, €9.50 day pass. 24/7 weekend service.
Athens
Athens metro modernized 2004 Olympics — clean, AC, archaeological displays at stations. €1.20 single. Underrated quality.
Worse than expected
Rome, Naples, Amsterdam (canal-walks faster than transit at center), Lisbon (charming but slow trams).
Strategy
Day passes vs single tickets — calculate your daily uses. Most cities: 3+ rides justifies day pass. Tap-to-pay contactless universal in major cities. Read our walkability companion for the no-transit-needed cities.
