Follow the road out of Massouri towards Arginonta and turn right for Vathy there. As you descend into the valley look for a football field and turn right onto a road opposite. Follow the road up till it meets the unpaved track that runs along the right side of the valley then turn left onto this until you can see the distinctive pyramid-shaped rock feature. Find suitable parking and walk until you reach the stone cistern and the the gate. Head right and walk uphill along the fence. until you reach the crag. There are some cairns along the way.The slabs are immediately left of the cave. Koukouvas is a new sector some 15 minutes walk (or 2 minutes drive) down the track from the Cave in the direction of Rina/Vathy. From the parking head across the terrain towards the obvious crag.
Park at points and clearings along the track below the various sectors, making sure not to obstruct local traffic as the track gets very narrow in places.
