Getting to Ljubljana is simple if you fly to the Ljubljana Jože Pučnik Airport. However, it's often cheaper to fly to Venice or Trieste and take a Flix Bus (or other) to Ljubljana. Busses cost around €20, one way.
Summer and winter are the big seasons in Slovenia for tourism. However, the weather in late spring and early fall is still very warm.
Depending on what you want to do (hiking for example) consider that snow stays in the higher Julian alps (above 1500m) until late May/early June, or even July sometimes.
In the summer, there are many free festivals and events happening in the city, generally around Tivoli Park, Park Zvezda, or in the Presernov Square.
Prices for restaurants and attractions are quite reasonable. You'll find plenty of options in the €5-20 range. Vegan, Thai, vegetarian, Balkan, Indian, Chinese, Italian, Mediterranean... it’s all there! Go to Visit Ljubljana to find out more about the city.
Taxis, or the city's bike share program, are the best ways to get around. Go here for more information.
Here are some other things do in Ljubljana:
Slovenia is home to many quality ski resorts: Kranska Gora, Krvavec, Vogel, and Kanin are some of the highlights.
Prices for lift passes vary, however they are almost all under €35 for day passes.
It's possible to connect to the resorts via ski shuttles, which depart from the main train station near the city center.
The Julian Alps are often referred to as "the biggest little mountains in the world".
In the summer months, you can hike to the summit of Mt. Triglav, Slovenia’s highest mountain. There are plenty of other itineraries for early season, such as Golica and Krn. You’ll need a car for this.
In my opinion, this is the best way to get around Slovenia; it’s affordable, flexible, and fast.
At Avant Car, you can rent a car for the weekend (3 days) WITH excess insurance coverages for only €55.
For an example itinerary, you can make a complete circular tour of the Julian Alps by driving from Ljubljana towards Kranska Gora, then to Bovec, Tolmin, and eventually back to Ljubljana.
Points of interest along the route:
Driving in Slovenia is a breeze. The roads are generally good, well marked, and traffic outside the cities is light. But regulations on drivers are strict and you can be stung with a hefty fine if you don't follow them.
Bosnia & Herzegovina might be the Balkan’s best kept secret. With cultural diversity, incredible landscapes, and a sad history, the country still feels undiscovered and exotic.
