Pula airport to Labin is about forty-five kilometres and takes forty to fifty minutes. That is the easy part. The question worth answering before you book is whether you need a car for the rest of the week, because that decides everything else.
Hire car
The desks are in the terminal, which is small enough that you cannot miss them. Book ahead in July and August; the fleet at a regional airport is finite and August exhausts it.
The route is straightforward: out of the airport, around Pula on the bypass, then east on the road that runs across the peninsula towards Labin and the Kvarner coast. It is a normal two-lane road, well surfaced, with a few slow stretches through villages. No tolls on this stretch.
Take the car if you plan to see anything beyond your own beach. Istria's interior — the hill towns, the vineyards, the truffle country around Motovun — has no useful public transport at all, and half the reason to come here is up those roads.
Bus
There is no direct airport bus to Labin. You take a bus or taxi into Pula's bus station first, then a regional coach east. It works, it is cheap, and it costs you most of an afternoon on arrival day.
The regional buses between Pula, Labin and Rijeka are reliable and used by locals rather than tourists. What they do not do is get you to a beach, a restaurant in a hill village, or the supermarket with your luggage. Buses serve Labin's lower town; the old town and Rabac need a further connection or a walk.
Worth it if you are staying put and walking, and if you have the afternoon to spare. Not worth it with small children and a week's luggage.
Taxi and private transfer
A booked transfer meets you in arrivals and drops you at the door. For a family arriving late, after a delayed flight, with children who have run out of patience, that is worth more than the difference in price — and it is a one-off cost, not a week of it.
Book it in advance rather than picking one up at the rank. Flights into Pula cluster around a few arrival times and the rank empties fast.
Which one, honestly
If you are here for a week and want to see Istria: hire a car, without hesitation. If you are here to sit by the pool and walk to the beach, and you would rather not drive on holiday at all: book a transfer in and out, and use the local buses for the two or three days you feel like moving.
The one combination that rarely works is no car plus an ambitious plan. Distances in Istria are short but the connections between small places are not frequent, and a day trip that looks like forty minutes on the map can become a whole day on a bus.

Arriving late
Flights into Pula in summer often land in the evening. If yours does, sort out food before you leave the airport area or plan to shop the next morning — village shops close early, and a hill road at eleven at night is not the moment to discover the supermarket shut at eight.
