Dalyan is another place to go,takes about two hours on the bus but worth it when you get there, you catch the bus from the bus station at the back of
Marmaris and they are co-ordinated from there,when we went we bought our ticket and it seemed like word went round, drivers and personnel all telling us what to do and where to change. Another place is Bosbaran (not quite sure of the spelling) not a lot to do but spectactular scenery on the way.
