Bus, subway or car rental: what’s the best way to explore Portugal?
Share
Portugal is compact, diverse and surprisingly rich in landscapes. From historic cities to hidden beaches, vineyards, mountains and small villages, there’s a lot more to discover than what fits on a subway map. That’s why choosing how to get around is one of the most important decisions when planning a trip.
Public transport options such as the subway, metro, bus, coach or train are useful, especially in large cities or on popular routes. However, they are not always the most practical or flexible way to explore the country in depth. Fixed schedules, overcrowding during peak seasons and limited access to rural or coastal areas can quickly restrict your travel experience. When time is limited, the way you move around Portugal can shape your entire journey.
Public transport: practical, but with limits.
In major cities, public transport is often the first choice. It’s affordable, familiar and usually well-connected. For short distances and urban exploration, it works well. But practicality doesn’t always mean flexibility, especially when your goal is to explore beyond city centres.
Subway or metro: fast, punctual and ideal for big cities.
The subway is the champion of urban efficiency. It avoids traffic and runs on predictable schedules. For city commuting or short stays in metropolitan areas, it’s hard to beat. That said, its advantages tend to fade outside city centres. Coverage becomes limited, stations are fewer and reaching less touristy destinations can be difficult or even impossible.
Even within cities, rush-hour overcrowding, reduced comfort on longer journeys and little flexibility outside peak hours can affect the overall experience. In practice, the subway often requires you to adapt your plans to the transport system, not the other way around.

With a car, you gain:



Bus: affordable, but time-dependent.
The bus is one of the most accessible transport options and often reaches areas the subway doesn’t. It’s generally cheaper and can be a good solution for travellers on a tight budget or those staying close to main routes.
However, traffic, delays, strikes and rigid timetables are common limitations. Add peak-hour overcrowding and longer travel times, and what seems convenient on paper can quickly become frustrating. When making the most of your time matters most, relying solely on buses or coaches can significantly limit how much you get to see.
Is it practical? Yes. Is it cheap? Also yes. But if time is a priority, the bus might not be the right transport option. These limitations become even more noticeable during peak travel periods, which is why travelling outside the high season can make a huge difference. Exploring Portugal in the off-season allows for quieter roads, fewer crowds and a much more flexible travel experience.
Why renting a car changes everything?
Renting a car shifts the entire travel dynamic. Instead of planning around transport schedules, you plan around what you want to see and when you want to see it. With Guerin, this flexibility goes even further. Thanks to a diverse and modern fleet, you can choose the car that best suits your trip, from compact models for city breaks to spacious options for longer journeys or family travel.
With a car, you gain:
- Full freedom over your schedule.
- Easy access to less touristy destinations.
- Comfort on long journeys.
- The ability to carry luggage or equipment without restrictions.

This flexibility is especially valuable in Portugal, where distances are short, roads are in excellent condition and the variety of landscapes makes road trips particularly rewarding. With Guerin’s wide range of vehicles, you can adapt your choice to every stage of the journey, whether you’re driving through historic city centres, coastal roads or rural landscapes.
