Where to refuel on the way south
Slovakia is the shortest way from Poland to Hungary, to Croatia via Hungary and to the Slovak Tatras. On the Kraków – Budapest drive (523 km) the Slovak section is a large part of the trip:
| Country | Share of route | km | Petrol (95) | Diesel |
|---|---|---|---|---|
| Hungary | 47% | 244 km | €1.73/l | €1.93/l |
| Slovakia | 34% | 176 km | €1.85/l | €1.97/l |
| Poland | 20% | 103 km | €1.52/l | €1.77/l |
| Route average | 100% | 523 km | €1.73/l | €1.91/l |
- If Poland is cheaper, fill up before the border – at Chyżne, Chochołów, Zwardoń or Barwinek. A full tank usually gets you to Budapest.
- If Slovakia is cheaper, refuel just after the border rather than at motorway stations, which are usually above the national average.
- On the way back, do the same in the other direction – the table above also compares Slovakia with Hungary.
| Route | km | Petrol (95) 7 l | Diesel 6 l | LPG 9 l |
|---|---|---|---|---|
| Kraków – Budapest | 523 km | €63.23 | €60.03 | €41.49 |
| Warsaw – Budapest | 882 km | €104 | €98.93 | €66.57 |
Fuel names and paying
Slovak vignette
Slovak motorways and expressways need an electronic vignette. Buy it on the official eznamka.sk website – it is linked to your number plate, so there is no sticker. Short, multi-day and annual vignettes are available. Avoid reseller websites that charge more for the same vignette.
