Anne, Lake salda is wonderful,the "sand" looks and feels pure white,it is made up of a Hydromagnesite mineral. You can find places to drive on the sand. The views around are great. Some interesting villages. A place to visit for a day or as we did overnight in Yesilova,the only "Hotel" but it had a very nice boudoir room, hand delivered beer from the market food made to order, located at the end of the lake. There are places to eat on the shore. It is far from being "developed". A good stop off if going /coming from Denizli or Isparta way. In our view a little unique and worth the effort.
