Skip pricey tours – instead, embrace the trams, buses and boats that give a more authentic (and cheaper) perspective of a city, with this extract from The Best Things in Life are Free.

Tram 28 – Lisbon, Portugal
Clatter into Lisbon’s steep, tight-packed Alfama aboard a classic yellow tram. The Remodelado streetcars (designed in the 1930s) that work route 28 are the best way to get into the district’s medieval alleys, although they can get packed so go early.
Single €2.85, day pass €6.

Number 11 bus – London, England
Ride a regular bus for a squeezed-in-with-the-natives view of the metropolis. Route 11 runs from Fulham to Liverpool Street Station via Chelsea, the Houses of Parliament, Trafalgar Square, St Paul’s Cathedral and the Bank of England.
Single £1.50, day pass £5.

Vaporetto – Venice, Italy
You’ll have to forgo the crooning gondolier, but opting for a public vaporetto (water taxi) instead of a private punt will save big bucks, while still offering views of Venice from water level.
Single €7.50, day pass €20.

Tram number two – Budapest, Hungary
Trundle alongside the Danube, with views up to the spires and turrets of Castle Hill, the Jewish Memorial (sculpted shoes on the riverbank) and grandiose parliament.
Single 350Ft, day pass 1650HUF.

Bosphorus ferry – İstanbul, Turkey
Travel between Europe and Asia for less than an English pound? Ferries crossing the Bosphorus strait do just that, linking both sides of this continent-straddling city. Sail at sunset to see the minaret-pierced skyline in silhouette.
Single 4TL.

Bateau bus – Monte Carlo, Monaco
Monte Carlo’s electric-powered ferry boats offer a smidgen of waterborne glitz in this razzmatazz Monaco harbour. They might not be billion-dollar yachts, but they offer the same views, and leave you with change to spunk at the casino.
Single €2.

Kusttram – Belgium
The ‘Coast Tram’ skirts Belgium’s North Sea shoreline – 68km, from De to Knokke-Heist. Some 68 stops dot the route, enabling a bargain Belgian beach adventure.
Single €3, day pass €5, week pass €20.

Transport card – Geneva, Switzerland
Pretty but pricey Geneva can make the impecunious weep. To ease the blow, the city will do you a deal: stay overnight and get a free Geneva Transport Card, covering travel on buses, trams and taxi-boats.
Free.

Mersey Ferry – Liverpool, England
Hop aboard Europe’s oldest ferry service on the 10-minute Seacombe-Pier Head commute, and as the Royal Liver Building’s twin towers inch closer, just try to stop yourself bursting into song...
7.20-9.40am, 5-6.40pm Mon-Fri; single £2.50, return £3.
