Ljubljana + Slovenia in 5 Days on a Budget

5 days: adding the cave nobody mentions first

Five days keeps the same spine as the 4-day itinerary , arrival, Bled, Postojna and Predjama, Bohinj, and adds the Skocjan Caves, a UNESCO site most visitors skip in favor of the more famous Postojna. Cut a day for the 4-day plan or the 3-day plan , or keep going with 6 or 7 days .

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. 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.

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 for the church and 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 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. Book a combined Postojna Cave and Predjama Castle tour if you’d rather not drive the roughly 55km, 1 hour route yourself.

Day 4: Lake Bohinj

Bohinj sits about 30km past Bled, inside Triglav National Park, with no fast direct bus, so this day works best with a rental car picked up for the stretch . The Vogel cable car from Ukanc runs 28 EUR return adult (22 EUR ages 14-25 and 60+), climbing to 1535m for views without Bled’s crowds. Swim, walk the shoreline, or sit with a coffee somewhere quieter than the icon lake a few valleys over.

Day 5: Skocjan Caves

Skocjan sits about 75km out via the A1 toward Koper; with the rental car still in hand from Bohinj, this is a straightforward hour’s drive, with free parking at the visitor center. It’s a UNESCO World Heritage site built around a collapsed doline and underground canyon, and it’s widely considered more dramatic and less crowded than Postojna, despite getting a fraction of the visitors. Ticket prices swing by season: 16 EUR in winter, 18 EUR in spring/fall, 22 EUR in late spring/summer and 24 EUR at peak summer (Jul-Aug); book ahead at park-skocjanske-jame.si in the busy months. Return the rental and head into Ljubljana for a final dinner.

Why put Skocjan after Postojna instead of first?

Sequencing works better this way because Postojna’s mini-train tour is the easier, more forgiving introduction to cave touring, while Skocjan’s walking route through the canyon rewards already knowing what cold, wet cave conditions feel like. Doing Postojna first also means the rental car is already paid for by the time Skocjan needs it.

Is Skocjan really better value than Postojna?

For the ticket price, yes: Skocjan runs 16-24 EUR against Postojna’s 34.90 EUR, and it delivers a UNESCO-listed underground canyon with noticeably fewer visitors. Postojna still wins on ease, its mini-train covers more ground with less walking, so the honest answer is do both if the schedule allows, and pick Skocjan first if forced to choose.

Five days at this pace runs close to 55-65 EUR a day per person, with the rental car covering three of the five stops cheaper than three separate tours would.
