After we arrived on Sithonia, we visited the Gost Town - a real large Lost Place area - and with an interesting background: Ghost Town (LP near Sarti)
And also here is one more cache: Bridge To Nowhere
But a real Lost Place?
We just found one!
It is a small one, directly on the beach, easy to access and easy to explore.
You can have a look, and then jump into the water. Or the other way round 
In the beginning it was one of the small beach kantinas. And it was certainly an novel idea to re-use this waggon.
After it had been given up, it looked like it was used as a 'habitation' for a longer time.
Then it has been abandoned and a lot of things just left there.
As in all LP's everywhere.
Have a look yourself... 
The cache container is a yellow mug with a white screw cap and a larger logbook inside. The container is hidden outside, you do not need to go in if you don't like to. Please put it back into the original location, then the cache will safely survive the next years!
The mug is big enough to contain some trackables of standard size.
