<font color='#0000FF'>The divings nothing to demanding, warm water & excellent vis.
Don't expect to see shoals of fish however there are fish about large groupers and quite a lot of Eels. Nothing very inspiring in the way of wrecks. You may also come across the occasional bit of amphora.
In the main its a market geared up to try dives for tourists
There's loads of dive boats now established there, these all tend to moor up immediately opposite the bazar in the old part of town. An exploratory walk down there in the evening will allow you to sus them out and perhaps haggle prices. From experience the smaller operators tend to take you to the better sites. As regards courses European Diving Centre are one of the biggest operators go out of Marmaris,(a PADI Dive Centre), there are a few others operating under the padi flag.
Enjoy
