Try a walk between t from / to Marmaris to Icmeler
Whenever I want to stress out go for some walk by the seaside... Between Marmaris and Icmeler which takes about 8 kms... Even you can stop by the cafes drink your coffee or ice cold beer... like to swim?... 5 steps away along the way. ;) ...through the evening or in the middle of the night next to the spectacular view of islands among the pine trees and enjoying the cool sea breeze!.... In night time could be romantic and sexy some parts of this way!... ;)
You have plenty of choice as there are many Turkish baths in Marmaris.
They offer you also the opportunity to have some SPA services: shoulder and neck massage - foot massage - facial masks - .....
At the Aegean / Mediterranean Boundary
Marmaris is a major tourist destination. It is a very busy place during summer months and the central part hardly reminds of the rather quiet place it used to be in the past. But it's nevertheless pretty, as the surrounding bay and mountains give a very nice backdrop. And with just a little driving around one can discover relatively unexploited spots.
"2006: No Hassle"
While visiting, we witnessed an effort from local authorities+business to do away with the "hassling" stereotype. There were "No Hassle" banners all around, reminding tourists and locals alike that the best kind of relationship is the one where the one doesn't press the other.
Driving south of Marmaris, one can reach the progressively quieter bays. The one we stopped at is Kumlubuk. It was a place where we could relax and enjoy the sea like you can't really do inside Marmaris.
Careful: No gas stations south of Marmaris towards those places. Better fill up while in Marmaris.
Kumlubuk is at the location of the ancient Greek (Hellenistic, Rhodian) town of Amos. Greek word AMMOS and Turkish word KUM mean the same thing (sand) but I'm not sure if that's more than a coincidence.
