before going into details...
Ok, first of... just some tips on orientation...
I will start with using the Bus station as a central reference point because it is VERY probable that you will reach Selchuk by either bus or dolmush and in either way end up getting off at the bus station. Two main streets intersect right at the bus station. One is the so-called Ataturk Caddesi (Caddesi pronounced as jadesi, like “j” in “joke”), a boulevard which is in the direction of Izmir. That is, if you are standing at the bus station and facing this boulevard, Izmir would be to your right (about 70 km from Selchuk). The other street is Sahabetin Dede Caddesi (Sha-Hah-Bet-Tin), that takes you to both Ephesus, the beach Pamucak (PAh-MOO-JUG, with a “k” instead of a “g” at the end) and to Kushadasi.
So if you figure that out, everything is quite easy. When you get off the bus and you go to the street closest to you, you end up on Sahabeting Dede Caddesi, you’ll see the ring-road, and that is the direction to Ephesus, Pamucak and Kushadasi. If you cross the Ataturk Boulevard and head straight, in two minutes maybe less) you reach the Tourist Information Office. Maps are given for free and you could use one.
The neighbourhood “behind” the bus station is actually the “central” part of Selchuk, and the more charming one. Well, depends what you are looking for. In any case, you can find many restaurants there, shops with nice souvenirs, banks and ATM machines (a suggestion, try taking out money instead of exchanging it or if you do go with exchange then do it with smaller amounts as the rate varies a lot, on daily basis). The streets that you will inevitably walk through are: Lienz, Siegburg and Cengiz Topel. On the last one you’ll also find the post office.
Ok, this should be enough as a starters.
I tried making a photo of my map at home and posting it here, but am not sure just how much you can see what it says. It was worth trying.
