Hot springs, mud baths and the Dalyan river trip (on dry days) are the most enjoyable options. The ancient sites are green and empty; Fethiye fish market and Marmaris bazaar are open all year. Most places in Ölüdeniz, Hisarönü, Kabak and Faralya are closed.

Who is it for?
For travellers who do not mind rain and want a quiet, inexpensive winter escape; not for anyone who needs guaranteed sun and sea.
