Absolutely loved the route as it offered some of the greatest views over the Dilijan and the national park. But don't underestimate because it was quite tough to do in a day in autumn especially if with a heavy backpack.
Interesting route, nevertheless it doesn't exist in fact in some parts, you're just passing through the bushes.
I hiked it in February and it the highest part (before descending) everything was covered in snow which was reaching at least my thighs, what made the route very challenging and dangerous at the end. The route is also passing at the very end through the private farm which is guarded by the dogs, so I had to take another route through the forest as the dogs didn't seem really friendly.
Nonetheless the route is very nice, I enjoyed it a lot :)
