Best countries for road trips

When travellers consider taking a road trip, especially in a lesser-known country, they have many factors to take into account. Plenty of questions come to mind, the answers of which can make the road trip smooth or bumpy. To make these considerations more manageable, we’ve analysed 31 countries in Europe and ranked them according to 17 factors in six categories.

The index below gives a ranking of how well-suited the countries are for a road trip. Each country’s final score was derived from the weighted average of all the factors and is presented on a scale from 1-100. However, we’re using each factor’s original values below for better clarity.

You can see how countries rank on the individual factors by clicking on the factor icons.

* Tolls policy has been categorised 1-4 with: 1 – denoting toll-free roads, 2 – payment required only for certain bridges/tunnels, 3 – some paid motorways, 4 – time-based vignettes
** As there is no official speed limit in Germany, 160 km/h was used for the sake of comparison with other countries

The factors presented are in the original data values but the total score is presented on a 1-100 scale, with 100 being the best, based on the normalisation calculations. For more information, please see the full Methodology.

Insights from the study

The rankings from this study are divided into six distinct categories: Weather, Safety & infrastructure, Pricing, Traffic & sustainability, Car hire and Nature & landmarks. Each of these categories uses multiple factors that each have different weights, depending on their impact on the attractiveness of a road trip.

The countries that are ranked the best for a road trip are likely countries with attractive pricing, great road conditions, plenty of nature to explore, competitive car hire rates and low traffic congestion. Subsequently, the countries that are ranked less attractive for a road trip likely have higher prices, unfavourable road conditions and/or don’t have as much nature.

Why Portugal, Spain and Luxembourg are the Top 3

Portugal landed the coveted No. 1 spot as the best country in Europe for a road trip. This is because Portugal scored well in several impactful factors, including road quality, amount of attractive nature and landmarks, and pricing of car hires. It also scored well in amount of sunshine, and has very little air pollution or road congestion.

Spain came in No. 2 for many of the same reasons as Portugal: good road conditions, good nature and landmarks, and lots of sunshine with little rain. It also has very few car accidents and reasonably-priced car hires.

While Luxembourg didn’t score high on weather, it came in No. 3 due to its amazing yet often-overlooked nature and landmarks. Reasonable car hire, accommodation and petrol prices plus toll-free roads also make it less expensive to explore.

Category winners

Deep dive into the six categories below to see the strengths and weaknesses of individual countries. Here too, you can see how countries are ranked by specific factors by clicking on the factor icons.


#1 Spain

It’s no surprise that Spain has fantastic weather. A combination of low precipitation and the most hours of sunshine makes Spain the ideal country to enjoy a sunny road trip.

Safety & Infrastructure

#1 Switzerland

Switzerland is a very safe country to drive in. It comes in first place as the country with fewest annual car accidents, and it also has the best road conditions. Generally, the countries that scored well here have fewer car accidents and good road conditions.

#1 Ukraine

This category ranks a country based on its petrol, accommodation and parking prices and its toll policies. Ukraine comes in first place because it has cheap petrol, very competitively-priced accommodation, great prices on parking and toll-free roads.

Traffic & Sustainability

#1 Netherlands

This category encompasses factors that affect traffic conditions like air pollution, congestion and number of cars per 1,000 inhabitants. It also takes into account the number of EV charging stations for those hiring an eco-friendly car. The Netherlands has an extremely high density of EV stations compared to its total land mass, plus relatively few cars for its population. Generally, countries that scored well here have less congestion compared to other countries.

Car Hire

#1 Slovakia

This category ranks countries based not only on how much it costs to hire a car but also car hire company ratings. Slovakia came in first with a winning combination of the second-cheapest car hire prices coupled with excellent car hire company ratings.

Nature & Landmarks

#1 Switzerland

This category comprises two factors that can often come to mind when considering a road trip in particular: the attractiveness of the country’s nature and the number of Heritage Sites. Switzerland takes the prize here with its majestic mountains, lakes and forests, but it also has the third-most Heritage Sites in Europe in relation to its land mass.

Data in six categories has been collected in order to rank European countries in terms of their road trip-friendliness: Weather, Safety & Infrastructure, Pricing, Traffic & Sustainability, Car Hire and Nature & Landmarks.

Within these categories, a total of 17 factors have been defined to reach a comprehensive overview of aspects that travellers may encounter and care about when deciding on the destination of their road trip.

A total of 31 European countries have been included in this analysis. The remaining European countries have been excluded due to incomplete data.

All sources have been accessed and data retrieved between 22 February – 10 March 2021. The numbers collected are based on the latest available data. See the full list of data sources.

  1. For each of the 17 factors, a weight indicating its importance has been assigned (1 – lowest, 5 – highest). Attractiveness of natural assets is considered to be the main driver for tourism, hence it has been assigned the highest weight. It is followed by Heritage Sites, road quality and a range of pricing factors influencing a decision for a road trip holiday. Lower weights have been assigned to factors in the weather category as well as others that are not considered the main decision drivers for road trip destinations (e.g. number of passenger cars per capita).
  2. Values within each factor were firstly normalised using formulas: score = 10 * (x – min(X)) / (max(X) – min(X)) and score = 10 – 10 * (x – min(X)) / (max(X) – min(X)) for inverted values (e.g. car accidents where the lower value is better).
  3. The weighted average score of the factors has been calculated for each country.
  4. Lastly, the weighted average score of the factors has been normalised using the formula score = 99 * ( ( (x – min(x) ) / ( (max(x) – min(x) ) ) + 1 to reach the final score on a scale between 1 and 100 (with 1 being the lowest and 100 the highest score).

The same procedure has been applied separately for rankings within individual categories to determine category winners.

Data sources & factor definitions


The Weather category comprises two factors:

Avg. sunshine hours per year in a country, based on avg. in major cities.
Source: Wikipedia

Avg. precipitation in depth (mm per year).

Safety & infrastructure:

The Safety & infrastructure category comprises three factors:

Speed limits
The highest possible speed limit has been taken into calculation (i.e. on motorways or the next highest speed limit in a country if no motorways exist). Since no official speed limit is in force in Germany, the value of “160 km/h” has been used for the sake of comparison with other countries.

Car accidents
Car accidents resulting in injuries and deaths per 1,000,000 inhabitants.

Road quality
The road quality factor is measured on a scale of 1(low) – 7(high).

The Pricing category comprises four factors:

Tolls policy
The countries have been divided into four groups based on their method of toll charging:

1 – toll-free motorways
2 – tolls only for certain bridges/tunnels
3 – toll collection at toll gates (fixed price or distance-based)
4 – motorway charged by vignette (time-based)

These four groups have been weighted with 1 ranked the best and 4 the worst. Due to the difficulty in comparing distance vs. time-based payment methods, the simplification has been made here that vignette as the unavoidable cost should be rated the lowest.
