This gorge runs to the Gulf of Corinth from Kalavryta, passing to the northwest of Mt. Helmos and east of Panahaiko massif, with forest (Aleppo pine), scrub, cliffs, and rocky outcrops, with good areas for birds of prey, including breeding lesser kestrels, honey buzzards, and short-toed eagles.
There are also various woodpeckers, crag martins, and alpine swifts. There's a monastery in the gorge, dramatically sited with high cliffs behind it, with some good plant life.
The gorge can be viewed from the train that goes from Kalavryta to the coast.
For the upper parts of the gorge, there's a road near Mega Spileo to Kalavryta which gives good access. The train can be caught at Diakofto just off the main Athens - Patras highway.
