I found the reward for reaching two of the locations somewhat underwhelming given the amount of effort expended reaching them. The were both located at thev tops of vcery steep hills. The two that I reached were :

Calpana - a short distance by taxi from the Calnic fortified church.

Costesti Catatuie - by bus from Orastie to Costesti, then a 2km walk to the bridge where two tracks lead to Cetatuie and Blidaru respectively.
