Pick Slovakia if you want castles, big mountains, thermal spas and low-key cities for less fuss, and pick Slovenia if you want lakes, a small coastline and a compact country that is easy to drive in a few days. For a trip that starts with a cheap flight search, Aviasales is our first pick for comparing fares to either country.
The two names are easy to confuse, and the countries share a few things: both are small, green, EU members and use the euro. Beyond that they differ in shape, scenery and travel style. Slovakia is landlocked and about 49,000 square kilometres, Slovenia is about 20,000 square kilometres and has a short Adriatic coastline of about 47 kilometres.
This guide is for travellers choosing between them, not for people who mix up the flags. For a full Slovak trip plan see 7 days in Slovakia.

Mountains and hiking
Slovakia's highest peak is Gerlachovský štít at 2,655 metres, in the High Tatras. The Tatras are compact and steep, with lakes, marked trails and mountain huts. Start with the High Tatras guide and the best hikes. Slovakia also has gentler ranges, gorges and caves, covered in Slovak Paradise and caves in Slovakia.
Slovenia is known for the Julian Alps, which reach further north and west. We have not verified trail conditions or hut rules there, so check the official park and alpine club sites before planning a Slovenian hike.
Cities and culture
Slovakia's capital Bratislava has an Old Town you can cross on foot in minutes, a hilltop castle and a river promenade. It is also about 50 km from Vienna. See things to do in Bratislava and whether it is worth visiting. Košice, in the east, is the second city, covered in our Košice guide.
Slovakia is also strong on castles, see castles in Slovakia, and on thermal pools, see thermal spas. Food is hearty, see Slovak food to try. Slovenia offers lakes and a short coast, which Slovakia cannot.
Slovenia's capital Ljubljana is smaller and sits near the centre of the country, which makes it a convenient base for short day trips. Wikipedia describes Slovenia's capital as geographically near the middle of the country, so most places can be reached in a day.
Getting around and how long to stay
Slovakia is longer east to west, so reaching the Tatras from Bratislava takes real time. See Bratislava to the High Tatras. Slovenia is smaller, so a short trip covers more of it. If you only have four or five days, Slovenia is easier to see in a loop. With a week or more, Slovakia rewards a slower route.
Money and daily costs
Both countries use the euro, so there is no currency exchange to plan for. We have no verified side by side price table, and prices shift with season and city. Capital cities and lake or mountain resorts are usually dearer than smaller towns in either country. For Slovak numbers, see Slovakia travel cost and Slovakia on a budget, then check current Slovenian prices on booking sites for the same dates.
A fair way to compare is to price the same three things in both places: a mid-range double room for your dates, a typical restaurant main course, and the transport you plan to use. Do that before deciding, because a general claim that one country is cheaper may not hold for your trip.
Common mistakes
- Confusing the two when booking flights. Check the airport code and city before paying: Bratislava for Slovakia, Ljubljana for Slovenia.
- Planning too much driving in Slovakia. Distances from west to east are real.
- Assuming a coast trip is possible from Slovakia. It is landlocked.
- Skipping insurance for mountain activities.
Our verdict
- Hikers who want big mountains: Slovakia.
- Lake and coast lovers: Slovenia.
- City break plus Vienna: Slovakia, via Bratislava.
- Short drive-through trip: Slovenia.
- Castles and spas on a budget: Slovakia, but compare current prices.
You can also combine them over a longer trip, though the journey between the two is not short, so check current rail and road options.
