We did 3 parts:
Dimitsana – Stemnitsa: Both villages are beautiful. The trail takes you through the gorge where you have a great view of the river Lousios. The nature is really something to see. Very peaceful trail, we encountered very few people. The monastery close to Stemnitsa is also worth visiting. Once you are at the top a great view awaits you.
Stemnitsa – Karitaina: Karitaina is really a very beautiful village. This is not part of the official trail and is not so well maintained, however it is really amazing. I would not recommend it to acrophobic people. Also consider that despite the fact the hike is short, it still takes a while to do since the path is not so easy to go through. You once more decent into the gorge of the river and, for the most part, hike along the river Lousios.
Elati – Vytina: An amazing part of the trail. First going through a cedar forest and along a small river. Really worth it. Again both villages are really beautiful. With a bit of lack we were able to get a cab from Vytina back to Elati for about 15 euro.
