A realistic guide to the economics and logistics of getting around without taxis in unfamiliar cities.

The default mistake: arriving in a new city, being uncertain about local transport, and using a taxi or ride-share for the first 2-3 days while you figure out the buses and metro. This can cost $10-20/day that's entirely avoidable.

The research that prevents this: before arriving in any city, spend 10 minutes on Google Maps to plan the route from the airport/bus station to your accommodation using public transport. The directions will show you the metro line number, the bus route, and the fare. You arrive knowing what you need.

Metro systems: most large cities have straightforward metro systems with English signage and digital payment. The learning curve is usually one trip. Fares range from $0.25 (Bangkok) to $3.50 (London). Always better value than taxis for any journey under 30 minutes.

Bus systems: harder to navigate without local knowledge. The useful tools: Google Maps (usually has bus route data for major cities), Moovit app (transit directions globally), and simply asking a local or hostel staff which bus goes where.

City transport cards: almost every city with a metro or bus system has a reloadable transit card that provides a discount over paying cash per ride. Load a set amount at the start of your stay. In Tokyo the Suica card also works at vending machines and convenience stores, making it doubly useful.

The bike share assessment: most major cities have public bike share systems at $1-3/day. For a city with separated bike lanes or low car traffic, this is often the best transport option — cheap, fast, and you see more than from underground.
