This picture was actually captured from the train when we came back from our trip to Constanta. This large lake starts to be visible as soon as the train arrives in Eforie Nord train station. After that, the train runs along the lake almost until it reaches Eforie Sud train station. Besides the large radio antenna, this lake is also associated with black stinky sapropelic mud. This mud is renowned for its health benefits. If you are searching for this black mud, you will find plenty especially in Eforie Nord. There is even the option to take mud baths in a complex located in Eforie Nord, not far from the train station.
