Ljubljana and Postojna Cave Day Trip from Zagreb

Postojna Cave is a 24,120 m long karst cave system in Slovenia.

Postojna Cave is one of the top attractions in Slovenia.

Not only will you see the cave, you will have some time to explore the capital of Slovenia-Ljubljana.

In 1872, cave rails were laid along with first cave train for tourists. At first, these were pushed along by the guides themselves, later at the beginning of the 20th century, a gas locomotive was introduced. After 1945, the gas locomotive was replaced by an electric one. About 5.3 kilometers (3.3 mi) of the cave system are open to the public.

Ljubljana has no world-famous attractions, which is just great: there's no need to hop from one place to another, taking photos and crossing the items on your checklist. You have all the time to stroll around and enjoy the city itself.

With a population of 300,000, it is one of the smallest capital cities in Europe. Slovenia's capital and largest city also happens to be one of Europe's greenest and most liveable capitals. Car traffic is restricted in the center, leaving the leafy banks of Ljubljanica River, which flows through the city's heart, free for pedestrians and cyclists.
