The short version
Central Antalya and Kaleiçi are made for walking. For anything further — Lara, Konyaaltı, the airport, day-trip sites — you'll use a mix of the tram, dolmuş minibuses, taxis and ride-hailing apps. Very few visitors need a car for the city itself.
Tram (AntRay & the nostalgic tram)
Antalya's modern tram line, AntRay, runs from the airport area through to the western districts, useful for a direct airport-to-centre run. Separately, a short heritage tram (Nostalji Tramvay) loops along the clifftop through Kaleiçi and past Karaalioğlu Park — more of a scenic ride than serious transport, but a pleasant one.
Dolmuş minibuses
Shared minibuses called dolmuş run fixed routes all over the city and out to Lara, Konyaaltı and nearby towns, and are the way most locals get around. They're cheap and frequent but route signage is in Turkish only, so they suit visitors who don't mind a bit of trial and error.
Taxis & ride-hailing
Taxis are widely available and metered; confirm the meter is running or agree a price for longer or airport journeys. Ride-hailing apps are increasingly used in Antalya and can be a more predictable option, particularly for airport transfers, since the fare is fixed before you book.
Boat trips
From the old harbour, boat operators run half-day coastal trips past the Lower Düden Falls — less a transport option, more an activity, but worth knowing it departs right from the old town.
