A dolmus is the local transport bus which is used to get around all over the resorts across turkey. Wherever you are staying these run on the main road routes and all you have to do is put out your hand and they will take you directly to
marmaris if your staying in icmeler. In
icmeler the dolmus buses you need have an orange strip down the side of them, you look for these striped buses when returning from marmaris also. The blue striped buses will take you into the armutaln districts of Marmaris these you can catch when you are in Marmaris.
They run frequently up until approximately 1am in the morning and were not to so long along 1.75ytl. Hope this helps.
