How can I manage costs?
Generally, Slovenia is not as expensive as its other western and central European counterparts. But there are still options available for you to further manage your budget.
Ljubljana Card
If you are visiting the capital (which you should), then you can definitely consider getting the Ljubljana Card. It not only gives you free entry to the Ljubljana Castle (plus the funicular ride) and a free cruise along the River Ljubljanica, it also covers all bus rides within the city. There are 24 hour, 48 hour and 72 hour options and you can read more about the card in detail here.
The cruise, the entry to the castle, plus a guided walking tour of the city will be enough for you to cover the cost of the card. So if you plan to do these activities, it will totally make sense to purchase the Ljubljana Card.
Transport pass
If you are not intending to drive or take day tours to get around, chances are that you will need some form of public transport to visit places such as Lake Bled or Lake Bohinj. The Slovenian bus services are generally quite affordable and doesn’t cost very much. But if you are planning to visit many places within a day, maybe a 1-day or 3-day transport pass will work well for you.
The pass allows you unlimited travel all around Slovenia and costs €18 and €22 for 1 and 3 days respectively. However, in order to enjoy using this day ticket, you need to also purchase a IJPP chip card for €5. You can read more in detail about this here.
Generally, I found the bus rides to be affordable. And even though I made 5 bus trips on my visit to Lake Bohinj within a single day, the total cost did not reach €18. Therefore I think it is not likely that this is worthwhile. Nevertheless, you can check the cost and timetable on the Arriva bus website to make sure.
Julian Alps Card
There are a few variations of the Julian Alps Card – one each for Bled, Bohinj, Soca Valley and Radovljica. Each variant of the card gives you benefits specifically for an area of the Julian Alps. To read in detail about each variant, you can refer to this website.
More generally, each variant gives you benefits to the attractions within the particular region, and which one to get will normally be driven by where you are staying. This is because you need to stay for a minimum of 2 nights in Bohinj and Soca Valley to be eligible for those respective cards, and minimum of 3 nights for Bled and Radovljica. Also, the card for Bled and Radovljica are free of charge.
The cards are not available all year round, so make sure to check the Julian Alps website for their applicable dates.
