Reconstruction

The final Georgian soaking report from Sascha, concerns that of Senaki / Menji.

Located in western Georgia the Senaki wikipedia page notes:

'At a three kilometer distance from Senaki the resort Menji can be found. During Soviet times it was a famous balneologycal and recreational water resort, which, nowadays, is severely damaged and abandoned'

So it's Menji resort, near Senaki.

Recreational Resorts in Georgia Facebook page has a post from 5 years ago:

'Menji Banleological Resort is located in Western Georgia Senaki District, in the Valley of the River Tsivi. There is subtropical climat, warm Winter and warm and humide Summer. Menji is known by its Hydrogen Sulphuride and Chloride Natriumian mineral waters, that are used for the treatment of the following deseaes: joint bones, peripheral nerval system, gynecological and heart, blood vein deseases. Season - whole Year. Sanatoriums are under reconstruction works right now'. 

Broken down
Sascha picks up from here:

'Each local can show the way [to Menji].
The Menji Sanatorium was in Russian times well known to treat skin and stomach illnesses. The sanatorium is some kilometers west from Senaki town.
The sanatorium today is a ruin, the last floor broke down and it is not recommended to visit the building.
Surprisingly, the sanatorium is still habited by refugees from Abkhazia. It is hard to believe that the refugees are in such poor living conditions since years and nobody seems to care about them.
After the Russians left Georgia, the sanatorium and the old spa were abandoned, however, the springs still exist a few kilometers further to the west'.

Let's have a look at these springs then. 
Sascha:

'A very friendly local took the pleasure to show me the real hot spring (after crossing by foot a river and private land).
Here again, the thermal water is boiling, soaking is impossible.
I could not determine where the water flows; I think it flows into the river, maybe it is worth a try to search further for some pools.
The local also showed me near a pond, two other cold springs that were used in the past for stomach problems. The taste was extremely disgusting, like liquid old eggs.
If anybody is interested in going here, let me know, he gave me his number and would be happy to show to other people the hidden treasures of the past. He speaks only Georgian, but as usual, after a while, a minimum understanding became possible'. 

 

'I asked him if there were no real pools left with a possibility to soak in. Unfortunately, this was not the case, but around 2 km away on the fields exists another source with healing powers'.

Holed
So Sascha continues:

'Without his help, I would never found the ramshackle (GPS: N42.283314°-O42.018571°) which was not closed and seems to be open for the public. This water was lukewarm and should be used like a shower but not for more than 15 minutes because it is highly mineralized. Not really sure if I understood for what illnesses the water is recommended, in any case the shower was very relaxing and the discovery of new spring was a great experience. The fact that (at least) 4 different sources with different healing effects are so close together, makes the Menji place quite unique in Georgia'.

The ramshackle

'Finally, on the road back, I stopped at the old spa of Senaki, one can imagine the beauty of the past. On the picture, you see on the roof some holes.According to my local guide, the holes are from Russian machine guns when troops destroyed the place before having left Georgia'.

Piped
I would have imagined that there would quite a bit of info on the internet concerning these hot springs. But that's not what I can could find.

As ever there's the fall back option of info from Thermalsprings.ru: 
with accurate precision Thermalsprings.ru notes that the former described hotsprings are those named Tzivi (Tsivi):

'Location: Tzivi village located west of district center of Senaki. Well Tzivi-north (provisional name) is located 400 m north of the train station Tzivi, as well Tzivi-South - B 1 km south of the station.

• Tzivi North Tsivi

Konstantin : This box from which protrudes a pipe 2, the water is very hot. When they were greenhouses. Even say there is a bath - but not in the public domain, it is necessary to make arrangements in advance. Just so purchased will not work. Near the river Tzivi - muddy.

• Tzivi-South

Constantine : Once there was a great resort, it is worth the distance a giant 9-storey building of the sanatorium - all dead and destroyed, tube from the source to the sanatorium - local dismantled. This remained a cottage. Water barely warm, but pleasant. You can drive any car'.

Though Tsivi in Georgian means cold ... 

Then the other only worthwhile share is that by Marleen Laverman on circumbendibus (Jul. 13, 2016):

'We decided to drive towards the mountains of the high Caucasus, but we take it easy.

We read about hot springs on our way, and because our last shower was more than a week ago, they sounded even more appealing to us. Of course, we know that our expectations shouldn’t be too high, but there are two hot springs on our way and one of them should be good enough to wash ourselves a little bit, right?

The first one we want to check out are the Menji hot springs. A spa resort, as our tourist map tells, with curing mineral water. And it showed a picture of a beautiful gorge with stones and clear water. Let’s go there!

We have to take a dirt road and arrive in Mengi village. When we ask for the hot springs, nobody knows about it. But after sometime they seem to realize what we are looking for. “Ah, Sanatorium!”, and they point in a direction further away.

So, we drive on, out of Mengi village. We drive over a train track, pass a Soviet style apartment block and drive into a street. Outside of one of the houses there is a Georgian woman and I ask her where we have to go for Mengi sanatorium. She points us back again. But further than some pointing, our conversation doesn’t go. Too bad that we don’t speak any Russian! It seems like almost everybody in Georgia seems to know at least some Russian.

We turn the bus and drive back. We decide to take the dirt road that leads to the river. We drive on and on and than we end up at a place that is used as the local trash heap. Hmm, oh no…

“Why aren’t there any signs? It should be a place you should visit according to this tourist map!” I say. We try to turn at the small dirt track and drive back to the main road.

“Ok, let’s drive to the nearby city to ask there, they will know for sure”, Roderick says. We continue our quest, Roderick is notorious for not giving up easily… After talking to some people, they point us back in the same direction as where we were coming from. We pass the old Soviet apartment block again. It seems unmaintained, but at the same time it is full with laundry and we see some people walking around.

“Maybe it is this place?” Roderick says.

“No, I can’t believe it, did you see the pictures??! I don’t want to believe it!” I say.

We drive around the building and eventually stop in front of an old, crumbling stairway made of stone. Three man are sitting in the shadow of the trees. We stop and ask them: “Menji sanatorium?” They nod their heads and point enthusiastically at the building behind them. We are somewhat confused: should we be happy that we finally found it? Or should we be sad because it really is the place that we were not hoping it would be?

“I will take our bathing suits and towels!”, I say, still hoping that we would find our paradise. When we walk up the stairs we see the remnants of the sanatorium, which our now used as cow and chicken sheds. And when we walk further we meet some of the people that live in the huge unmaintained Soviet style apartment block. With gestures we try to explain what we are looking for: we make movements like we are swimming or bathing – and in the end they point in the direction of the scrap heap again… Disappointed we walk down to our bus. Maybe we should accept that we can’t find it.. But it looked so good on our map!'

The quest continues with little success. 

And so does this finish our final entry on Sascha's entries on Georgia. Certainly a lot to discover.
