It would be a long walk. It took about 20 - 25 minutes on the bus. You catch it from the junction where the Robin Hood/ Olive Tree restaurants are

We hired a car to go there from Ovacik, only took around 15 mins I think. It would be a nice walk as long as it's not too hot although as you near the Ghost village there are a lot of trees that would give shade. I think the dolmus only stops there once every hour.

Depending how fit you are it is walkable but it would be hard work in the heat-dolmus only costs about £1.25 so probably best to catch that to be honest.
We can recommend Cin Bal restaurant (on the right as you reach teh village)- barbeque and cook your own food-it's great!

We too were told about a nice restuarant in the Ghost Town. If its the same one (I dont know the name) we were told that if you called them they would pick you up and bring you back. We stayed at Pinara Apartments, Ovacik and the restuarant was well known there - hopefully will give it a try.

if the restaurant is lavessis wine restaurant they have there own pick up bus just phone them to book stunning setting with great food would reccomend we love it there and you can smoke the water pipe as well
