No special access issues
The most efficient approach, coming from the north is to take the national road connecting Tripoli and Astros. At the main junction (37.43653, 22.47830), follow signs toward Ano Doliana, Kastri, Mesorrachi, Oria, and Agios Petros. Follow this road until the village of Agios Petros.
The sector is located directly opposite the village of Agios Petros. It is easily visible from the road, with parking (37.3275422, 22.5578727) available on-site and a very short approach.
Coming from the south you wanna leave Astros to the direction of the Monastery Panagia Malevi. From there it's a five minutes drive to the sector. As soon as you see the village of Agios Petros you will also have the climbing sector in sight at you left.
