Thank you team, for sharing this route. I made it in almost 8h and walked 20km from the top of Odzun. Sometimes, was not obvious where to go.:-) but it’s ok. A lot of fun on the road: red squirrels, goats, mountain cows, dogs, dangerous horses.

We did this hike in mid-July 2022. Took 8 hours backpacking. Beautiful views, well marked trail. But the overgrowth along the way was brutal. lots and lots of thorny bushes slowed us down significantly. The start point is difficult to find and bear in mind that it connects to Goats Goats Goats trail - so don't just start following the white-red-white markers. Use the online map. The first half was without much shade and along the side of a cliff. Walking through the Soviet era train yard was fun and we had lunch there by getting some bread and supplies from a market. Some of the climbs on the second half were exceptionally challenging, but had less overgrowth than the first half. There were several water points (pipe out of the ground) at the top of those climbs. Sanahin is not that developed and we couldn't find a dinner spot. We camped at the school next to the Mikoyan Bros museum - that was beautiful. The next morning had breakfast at the Kernal Hotel. Overall very challenging hike that we're glad we did but won't do again.
