No special access issues
The most efficient approach, even when traveling from the south, 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 for approximately 14 km (about 20 minutes) and park at the church square in Mesorrachi village (37.37063, 22.54123).
From the square, begin the approach hike to sector Kakavo heading north. Walk through the village and continue onto the dirt track until you reach the first sharp right-hand bend (from here you already see the wall with it's sub-sectors). Look for a small, marked trail on your left leading into the forest. Follow the well-marked path, cross a small creek and continue until you reach the first routes at the small cave and wall.
