Just an update - I was a bit disappointed with the walking possibilities around Altinkum, we walked along from the Tuntas Beach but a few minutes later had to divert around the Palm Wings resort and from there on it was just a bit barren and featureless from what we are used to on the south coast, the only trees were in the first few minutes. We made an afternoon's walk around the bays but it hasn't a lot to recommend it, perhaps in the spring when the wild flowers are out.
Getting to Didyma was simple, just up the road.
Well, we made it to Miletus but were not able to take the hourly yellow bus to Balat, no ticket no ride. We asked around but no one knew where to buy the tickets and having been there for over an hour and a half had almost given up. I was handed a phone by a local bus man, it was an elderly dolmus driver from Balat who spoke a little English and said he would come and pick us up in 30 minutes for a set price, drop us off and collect us again. So that's what we did, hired our own dolmus and a fine afternoon out was had by all!
We went to Priene from Soke while we were staying in Kusadasi, easy - we started off in Eski Doganbey and then took a dolmus to Gullubahce and walked up to Priene, an interesting day out.
I will be ever grateful to the local people as I left my camera on the wall in Gullubahce but didn't even know. The woman in the shop opposite must have seen it, phoned the dolmus driver (they always know the number), he spoke to a student at the back who had enough English to say my photograph machine had been left behind and to stay on the bus. We thought as we sat on the bus that we would have to go back on the next run but another dolmus driver brought it back for me an hour later. All this had gone on without any intervention from me, I was very grateful to get it back and for all their phone calls. As I have always said, in Turkey anything is possible. Thanks for all the advice.
