One day I was spending a few morning hours on Agios Sotis beach. Then I decided to try to reach the highest top on the island, which is the mountain of Profitis Ilías. It's 751 meters above the sea level.
I was renting a motorbike during my stay on Milos, which in this case, made it easier to reach the top, since I was able to drive uphill rather much of the distance. This was to take a chance, as the renting company didn't have any support if something happen with my moped in that part of the island. The road was in a very bad condition so I was perhaps lucky to avoid stones that easy could result in a flat tire. Actually I had a flat tire the day after, likely caused by my drive the day before.
The last part of the distance I had to walk often on very steep paths. It was a very nice walk though, with very colourful scenery, sometimes with strong green and yellow vegetation (see photo).
On the top I found a small church and this seems to be very common in Greece. The view is breathtaking; you have the complete island beneath your feet.
As I was on the top I discovered that there was a road construction going on from the western direction, so I suppose that it's possible to drive all the way to the top today. Anyway, I prefer to walk, since this is a complete another experience. When you walk you would feel the heat, smells, sounds and surroundings to the fully extent.
