You'll probably get to Kaş by minibus from Fethiye or Antalya, but national bus companies Kamil Koç, Metro and Pamukkale serve Kaş as well with direct night buses to Ankara, Istanbul and İzmir.
Among the main minibus companies is Batı Antalya Koop (Western Antalya Cooperative).
Here's information on ferries to Meis Adası (the Greek island of Megisti/ Kastellorizo, Castellorizon). (You can stay overnight or for several days on Meis/Megisti, but there is no guarantee that there will be a place for you on a return voyage.)
The nearest airport is Dalaman, Muğla and is about a 2 hour drive from Kaş. The Antalya airport, however, is the nearest international airport and is a 3 hour drive away.
Since Kaş is a relatively small beach city, it is quite reasonable to walk or bike everywhere within the city limits. If you are wanting to leave the city and visit nearby spots such as Patara, you can go with a tour group, hire a taxi or private transfer. Everything else is easily accessible by walking, but just be sure to wear comfortable shoes.
Distances & Travel Times
Antalya: 185 km (115 miles) NE, 3 hours & 35 minutes. There are mini buses and several large buses daily in the warm months (June to September) between Antalya's main bus terminal and Kas's otogar, stopping at Demre/Kale, Finike, and the access roads to Olimpos, Çiraıi, Phaselis and Kemer. Fewer minibuses off-season.
If your starting destination is the Antalya airport, you can take the Havaş bus (it comes every hour) to the Antalya Otogar (bus station). Once you are there, you will want to go through the doors marked “Şehir İçi” and inside you will see many counters with different company names. There are a few companies that travel to Kaş, one of them being Bati Antalya. Their buses leave every hour on the hour and take about 4 hours to get to Kaş.
Dalaman: If your starting destination is the Dalaman airport, one of the easiest ways to get to Kaş is via their hourly transfer service. However, be sure to make a reservation ahead of time as this is required. For this, you can be in contact with your hotel or use this website to book a transfer. The shuttle takes about 2 hours.
For a cheaper option, you can take the airport bus called the Havaş, which will first go to the city of Fethiye and then drop you off at Kaş. While this is the most budget-friendly option, it does take the longest.
If you like driving, you can easily rent a car from the Dalaman airport as well.
