No special access issues
From Heraklion, follow the old National Road 90 towards the village of Marathos. From the port of Heraklion, it is approximately 20 km and about a 25 min drive.
You can already see the climbing sector from the road. Parking is available very close by, right at the hairpin turn. From there, access to the sector is just a 1 min walk on foot.
Once you arrive, you can choose between the upper wall or the lower wall.
