Perched on top of the hill is a Communist-era monument that from a distance looks like a huge washing peg. You can drive all the way up to the monument – highly recommended especially when it is dark as this is one of Bulgaria's better dark skies locations. In the future you may not remember what that monument stood for. However, what will probably stay in your memory is the drive itself.
In fact, this country is full of drives like this, through mountains, plains and the seaside, but you have to know how to find them.
