Slim

Continuing with our soaking recherche of Georgia, Sascha now introduces us to Nokalakevi hot spring, in the northwest of the country.

Wikipedia enlightens us on the relevance of Nokalakevi :

'Nokalakevi (Georgian: ნოქალაქევი) also known as Archaeopolis (Ancient Greek: Ἀρχαιόπολις, literally meaning ancient town) and Tsikhegoji ("Fortress of Kuji"), is a village and archaeological site in the Senaki municipality, Samegrelo-Zemo Svaneti region, Georgia'.

Absolutely no mention of hot springs are made.

But Sascha knows better: 

'These hot springs were mentioned by Lonely Planet.  
Drive first to the beach of Nokalakevi (on the left hand side, there is a hotel, the only one in the village). From here, continue the road up for around 1 km, on your right hand side there is a spring sign and a small gravel road that you need to take that leads down to the river. The last part of this way is very rocky and steep, a high clearance car is recommended, otherwise walk the last 200 m down to the river.
You first reach the 2 springs that have boiling temperature and therefore a fence surrounds the hot springs. The thermal water flows into the river on two points'.

Two points, two options for soaking:

'Head first to the pools on you left hand side and check if there is some place free.
There are some small pools near the river and the water is only around 37/38° warm. However, warm enough to relax for hours in the small pools. Unfortunately, the pools are not very deep, you must be either very slim or only half of the body is covered by thermal water.
The river invites for a refreshing soak.
Some even flow with the river to Nokalaveki beach'.

 

Or:

'The second option is to climb down the stairs right from the little bar down to the river. 

On your right side, the hot water creates a cascade. Many man-made pools nearby the river can be found, but the hot water comes also from the ground which made the pools to hot by the time of visiting in July'.

As accustomed in the other Georgian hot springs there's little to add / find in the internet. 
The said Lonely Planet lets us in own some info:

'Some 60km from Zugdidi via Senaki, Nokalakevi is a picturesque and historic ancient Colchian royal town and fortress. A tunnel leads down to the Tekhura River from the grassy grounds, and admission includes an interesting archaeological museum. Excavations are ongoing (see www.nokalakevi.org). About 1km upstream on the Tekhura you can take a dip in soothing thermal pools'.

The website Eurasia adds:

'Beyond a house a tiny path leads up to a fort on a hill (as opposed to the citadel, higher up and reached by a jeep track to the north, a pleasant walk of an hour or so each way); at the northern end of a very solid 19th-century girder bridge (for pedestrians and bikes only) across the river are the remains of a 5th-century bathhouse (with three rooms for three different temperatures, and red ceramic heating elements). As in most Georgian forts, there's a tunnel down to the river, to get water during a siege. On the far side of the river is a popular, if stony, beach, and a road leading up into a dramatic gorge with popular hot springs a kilometre or two along. It's possible to stay at the archaeological base if it's not full'.

A youtube find:

 And finally, Thermalsprings.ru jots down the details :

Location: near the Archeopolis Nokalakevi on the right bank of the River Tehura.

Infrastructure: two wells.

Description: Old self-flowing wells, most likely drilled in the 1970s. Pillows of carbonate sediments formed around the wells, which descend along the river terrace to the river bed. Next to the riverbed laid baths of boulders in which you can soak in the warm water.

Water type: pH = 6.9, fresh M = 879 mg / l, T> 62.7 ° C.

Optional

Continuing with our Sascha soaking saga in Georgia, he now heads more westwards, to the the the small town of Vani.

There doesn't seem to be much on offer in the town, though of course the only reason why Sascha would want to come here, is for a local hot spring. Sascha is hooked:

'Definitively my favorite hot spring in Georgia and my first geyser soak [ever]'. 

And though we are near Vani, Sascha continues:

'It is located a bit in the middle of nowhere and I found the geyser only after many discussions with locals (who often were not even aware of the spring)'. 

Concerning users / usage:

'However, it appears that the geyser is quite common amongst young locals in the evening. As there is no shadow at all, the early morning or evening soak is indeed a good option. Wild camping should be possible, if you don’t want to stay in a guesthouse in Vani'.

The soaking experience itself: 

'The water of around 43°C sorts out of a geyser and flows in 3 pools. Two of them are sufficient deep to soak the whole body. There was some littering around the pools but once in the pool, the littering is not any more visible and the pools itself are very clean. Some sulphur smell, the ground of the pools are shaped by the minerals of the water, some sand can be found. The surrounding itself was quite beautiful, wild horses were passing by and mountains are visible by far. Bring enough drinking water with you; the sun exposure is extreme when visiting the geyser at 11 a.m. like I did'.

Getting there:

'How to get there: take the road from Vani center to Baghdati [town] for around 7 km. Then take a gravel road to the left for about 1 km. On your right side, you will find the geyser.
GPS coordinates: N42.104196° – O42.586213°'.

Dumped

Taking a more holistic view or in other words delving into the internet, let's see if there's more info available.

There's not much: you'll find the odd photo here or there on instagram (following), other than that it seems to be a dusty neglected corner of the internet. 

Visit Kutaisi notes:

Close to the village of Bzvani [or Vani?] there are a few hot sulphur spring pools which posses healing qualities. Some of them are open to everyone, available free of charge and practically the only visitors are local people. One of the pools is located in particularly beautiful spot – in a field, in the middle of nowhere. The silence and surrounding meadows create a tranquil atmosphere which makes you feel like you the only one in the world. When you look to the South you will see amazing views of the Lesser Caucasus Mountains.

Thermalsprings.ru also reports on Vani:

'Location : left bank of the river Rioni terrace, 1.8 km to the north from the road Bagdati-Vani, between the villages of Vani and Amagleba. From the road to get there can be a simple machine.

Infrastructure: no.

Description : 100 m from the riverbed Rioni, there are 4 source close - to look for. The water is very nice warm, not hot, shallow pool. Near the river Rioni, can be washed after bathing. But the place you should choose, as where the local road builders dump trucks loaded with pebbles'.

The local government website also mentions the hot springs, but not as a big attraction; apparently tourists should visit Vani for it's history. It's wording (translated):

'Resort "raising [a translation of ამაღლება]"The balneological resort is located in Imereti lowland on the left bank of river Rioni, 8 km from Vani, 80 m above sea level. Mineral thermal waters contain sodium, chlorine, carbon dioxide, and celery. They are treated by: chronic arthritis, hypertensive diseases, atherosclerosis, radiculitis, cardiosclerosis'.

The geyser is not the only hot spring in the area. Theculturetrip in an article named

'7 hot springs in Georgia you must visit'.

notes the  Sulori Spa resort:

'Located in Vani municipality, 11 kilometres (6.8 miles) away from the city of Vani, this resort took its name from the Sulori river. During Soviet times Sulori was a favoured visitor spot, and hosted hundreds of visitors each season. Today, the hotel is still going strong, with 32 individual bath rooms. People usually come here to treat conditions affecting the musculoskeletal system, peripheral nervous system, and metabolism to name a few'.

Other than the above there's not much to add.
