On the question: "What is the hardest Bisna tour?", there is one true answer: "Definitely Tskhvandiri Lakes and Khuro Range".
Tskhvandiri Lakes are located in Chuberi (Nenskra Valley), Zemo Svaneti [Upper Svaneti] (Mestia Municipality), in particular — in the basin of Dalari River, the right tributary of Nenskra River. Nenskra itself is the right tributary of Enguri River.
Tskhvandiri Range seen from Tita village
A minibus leads us to Tita, the last village of Chuberi. We begin hiking from here. Tskhvandiri Range, which is to be crossed by us, can be seen from here and looking at it we can't believe that our track lies that high.
After several km on unpaved off-road, we pass the border-keepers' checkpoint, and shepherds' settlement and begin to ascent on a very steep slope of Tskhvandiri Range.
First section of the ascent
The ascent is extremely difficult and can be divided into 3 sections:
1. Narrow ravine made by a small stream — on this section we mainly have to hike (sometimes — climb) on stones and rocks.
2. The very steep slope after the ravine — this is very short section but too steep and there are very few things to hold a hand on.
3. Steep field — this section demands from us the psychical sustainability as the grass is very slippery and there are very few things to hold a hand on as in the second section.
After ascending the three sections (as wells as the transitive sectors between them) we reach the campsite. This is the top of one of the "forks" of Tskhvandiri range. There is a good view on Nenskra Valley from here.
The frozen lake
From here we have to hike on the slopes of Tskhvandiri range, cross the range and descent to a frozen lake.
There is one more range to cross from the frozen lake to reach First Tskhvandiri Lake. We have to be extremly cautious on this section. Finally we see First Tskhvandiri Lake.
First Tskhvandiri Lake
We can set the camp on First Tskhvandiri Lake and go for seeing other neighboring Tskhvandiri Lakes without backpacks.
