Follow the road from Leonidio towards Paleochori. After approximately 15 km from Leonidio’s main parking area, you'll reach a left-hand turn (37.163912; 22.746766). Here, you'll spot a cairn with painted markings indicating the start of the approach. From there, head down to the riverbed, cross it, and then ascend the opposite side of the hill, following additional cairns and paint markings.
