a bit modified due to the start in Heshkili (arriving there by car from Lakhushdi)

Take a cable car ride to the top of Zuruldi range, then head east. Walk between trees, cross small meadow and you will come to bigger dirt road. It will take you all the way to Mentashi transmitter, which is already visible to the east. There is only one crossroad halfway, in front of a small hill - if you take left branch, you will climb to the nameless transmitter (limited views), if you take right one, trail will bypass the mount. But no matter which path you take, both will merge again and you will have to climb hundred meters to another transmitter.

Mentashi hill offers breathtaking views in all directions and is an excellent place for a break. Majority of people turn back here and return to the cable car. It's also a viable option as views when riding downwards are even better (as you see Ushba all the time without a need to twist your neck).

But we continue eastwards. Descent from Mentashi is tricky as the terrain is very steep and the path not always visible (to put it mildly). Be careful. You need to make it to the meadow in the northeastern direction. Once there, find a small path heading northeast. Follow it, cross several pastures and belts of trees.

After two kilometers, you will come to a spot where the trail turns north and dives into the forest. From here, it's supposed to continue to Mulakhi village. First sections are decent, but further stages are in a poor shape so I don't recommend it. But if you have time, you can make a small side trip - after first 300 meters, there is a meadow with nice views of Mt. Ushba.

In case you want to go directly to Tsvirmi, keep walking east. Follow the grassy path between trees - on your left will be a dense forest, on the slope below you a small group of trees. Once you walk pass this grove, turn right and descend some 50 meters. You will find a path, which soon turns into regular dirt road - too narrow for a car, but wide enough for a cart. This track will take you all the way to Tsvirmi.

Tsvirmi is a lovely hamlet, barely touched by tourism. If you want to spend a night here, you will stumble upon a guesthouse soon after you enter a village.
