The source for this path is a recording of my own Garmin GPS device and additional re-checked with a second GPS devide that my hiking buddy carried.
I walked the path together with a friend after careful preparation and with the help of the former austrian manager of the Kallergi Hut who confirmed that we got the right track and who was in contact with us during our hike.

If you walk into Tripiti Gorge following the most 'obvious' way YOU WILL END IN A TRAP!

I decided to post the precise record of the ONLY POSSIBLE SAFE way in OSM.
The path is an old shepards path and actually not too difficult to walk if you stay on the right track. Basically you have to walk on top of the ridge between Tripiti and Klados gorge and go down at the very end of the ridge.
Any attempt to walk down earlier to the bottom of the gorge (because it looked easier) is dangerous and you will risk your life.
