The world's 7 most expensive public transit systems

All-day fare: $13.50

Munich's system is unique in that travelers can purchase both single and partner tickets.

Companions reduce the cost per person from $13.50 to $8.34. But if you happen to be adventuring alone, expect the full fare.

All-day fare: $13.60 

Better buy your ticket before boarding the train or bus in Stockholm, or any other part of Sweden for that matter.

SL riders without a ticket will be charged a fee of roughly $142, since tickets can't be purchased onboard.

All-day fare: $16.89

Like many European countries, travelers in Norway can purchase tickets based on how much ground they'll be covering.

Zones 1 and 2 cover the entire Metro system in Oslo and bus routes to the suburbs. The fare covers an all-day ticket for those two zones.

All-day fare: $19.61 

Paying nearly $20 for a daily metro ticket is almost reserved for the foolish, since Copenhagen has such a sophisticated and convenient cycling culture.

Approximately half of all Copenhageners commute by bike each day.

All-day fare: $22.51

The cost for tourists to ride the water bus is sky-high compared to locals in Venice. A 75-minute trip costs $8.45, and the daily cost of $22.51 isn't a much better deal.

Many tourists are encouraged to walk the narrow paths snaking through the city.

Fare: $26.06

London is notorious for its high cost of living, public transit included. 

Visitors that buy the daily Travelcard for $26.06 can earn full access around the city or reduce their expenses by only traveling through certain zones.

Fare: $34.89

While a trip through Switzerland offers no shortage of memorable views, the ones found along the Zurich metro come at a cost. A day ticket comes in at over $34. 

And that's only the second-class ticket. First-class transit costs $57.84.
