This was mainly a car trip for two days. About most of the places I knew from a meeting with friends where I took notes and strictly followed them.
We first arrived at Assara - a place with interesting clustered rocks with a lot of rock niches on.
Here is the biggest one with the niches.
Then we moved to the fortress Moniak. It is situated on a very panoramic place, but there is not much left of it.
But the next day we were pleasantly surprised by the castle Ustra.
Unfortunately the Ustra hut situated in the foothills seemed to be abandoned. Our trip ended with Perperikon - an ancient Thracian city.
