The tour through the gorge was very impressive and Nikos was a great guide. We needed a total of 6 hours including several small breaks. The hike initially goes downhill into the gorge, then through the gorge (flat parts and partly slight hills) and finally out of the gorge via a stepped path. Niko's wife picked us up punctually upon arrival and drove us back to Monodendri. Most of the hike was shaded and on the climb up at the end we were lucky that it was a bit overcast so it wasn't too hot. Nikos shared a lot of knowledge about the environment, plants and animals with us and was always careful that we crossed the paths safely. Highly Recommended!
