Ljubljana + Slovenia in 3 Days on a Budget
3 days: Bled and the caves, the classic combo
Three days is enough for Ljubljana’s two biggest Slovenia day trips without rushing either: land and get oriented, then Lake Bled, then Postojna Cave and Predjama Castle. Add Lake Bohinj with the 4-day itinerary , or keep going with 5 , 6 or 7 days .
Book these before you go
- Book a Lake Bled day tour if you’d rather not time the bus yourself.
- Book a combined Postojna Cave and Predjama Castle tour , or buy the cave’s own bundle ticket at postojnska-jama.eu to skip the queue.
- Rent a car for the two days out if you’d rather drive both trips yourself.

Day 1: land and get oriented
Fly into Joze Pucnik Airport (LJU), about 26km north with no rail link at all. The regular public bus to the main bus station runs roughly 4.10-4.50 EUR and takes 30-50 minutes; a prebooked GoOpti shared shuttle runs about 12-15 EUR a seat if booked well ahead, or 35-50 EUR for a taxi door to door. Check into somewhere near the bus station, since that’s where tomorrow’s Bled bus leaves from. Spend the afternoon on Ljubljana’s free core: Preseren Square, the Triple Bridge, and a walk along the Ljubljanica embankments, all free and walkable in a couple of hours. Grab an Urbana card if you’ll ride buses more than once; a single fare costs 1.50 EUR with a 90-minute transfer window, versus the same 1.50 EUR but no transfer if you just tap a bank card.
Day 2: Lake Bled
An Arriva bus from the main bus station runs roughly every 30 minutes and costs about 6-8 EUR one way, cheaper on weekends than weekdays, reaching Bled in about an hour. Take the first bus you can catch; the lake fills with tour buses by mid-late morning. The pletna boat to the island runs 20 EUR adult, cash only, plus a separate 12 EUR if you want inside the church and up the bell tower. Bled Castle above town costs 19 EUR adult. Skip the lakefront cafes for kremna rezina (cream cake) at 7-9 EUR a slice; walk a few streets back for the same cake around 4 EUR. Book a Lake Bled day tour instead of the bus if you’d rather not time it yourself.
Day 3: Postojna Cave and Predjama Castle
Postojna Cave alone costs 34.90 EUR adult; Predjama Castle, billed as Europe’s largest cave castle, adds 24 EUR separately. Check the park’s own bundle (cave, castle and the Vivarium) at postojnska-jama.eu first; it typically beats buying the cave and castle apart by a few euros and throws in a third stop for free. The cave sits at a constant 10C year-round, so bring a layer even in August; rain jackets rent for about 6 EUR on-site if you forget. Book a combined Postojna Cave and Predjama Castle tour if you’d rather not drive the roughly 55km, 1 hour route yourself. Return to Ljubljana in the evening for your onward trip.
Is 3 days enough to see Bled and the caves properly?
Yes, for a first pass at both. A day each gives Bled its early-morning window before the crowds and gives Postojna and Predjama a full afternoon without rushing the cave tour or the castle climb. What it doesn’t leave room for is Lake Bohinj or the coast; those need the longer versions of this plan.
Should you do Bled or the caves first?
Either order works, but Bled first uses your freshest energy on the trip that rewards an early start the most; the caves run on a fixed tour schedule regardless of what time you show up, so there’s less to lose by doing them second.
Three days at this pace runs somewhere around 45-60 EUR a day per person once buses, tickets and a casual dinner are added up, cheaper than any version that swaps a bus for a private tour on both days.
