In Antalya Province, there are numerous buses running up and down the coast connecting Antalya with the smaller towns. Phaselis is off the main highway, however, so not just any bus will do.
I visited Phaselis as a day trip from Antalya city. I took a bus from the main otogar (bus terminal) run by the company Kemer Tur, and it was ultimately headed for Tekirova.
While there’s no clear timetable, buses seem to leave hourly. As of 2020, bus tickets cost 14 TL each way, with the ruins themselves costing 45.
A majority of foreign visitors to Phaselis are people staying in the neighboring resort town of Kemer. While Kemer has its own beaches, they lack the ruins and unspoiled nature of Phaselis, so many opt for a trip over.
If you’re staying in Kemer, you can simply find a bus at a bus stop in the center of town. Be sure to confirm with the driver that they’re headed for Phaselis. Most bus drivers around these parts speak decent English.
My journey from Antalya to Phaselis was pretty straightforward, but I was surprised by how long it took. The journey took nearly 2 hours in total, as the driver lingered quite a bit in towns along the way.
Getting back to Antalya (or Kemer) from Phaselis is easy. Simply walk back to the ticket booth area and a direct bus will eventually appear.
It’s also possible to visit Phaselis as a day trip from Olympos. While it’s much closer to Phaselis than Antalya is, Olympos has its own seaside ruins.
