It doesnt take long to get to Armutulan. If you get a dolmus say around the Point Centre in
Marmaris then the journey to Armutulan will only take around 10+ mins. The terminus is in Armutulan Square. Theres a few nice bars and restaurants in the Square itself, for example, Mustis Fun Pub but you only need to walk for a few minutes and you will come to the main Adnan Menderes Cad. Theres loads of bars/restaurants right along that street.
Alternatively you can go from
Icmeler right along to the Old Tansas and get a dolmus there. That will take you another route but you will still end up in Armutulan but along the other side. Hope this helps.
