How much does Prometheus Cave cost to visit in 2026?

The standard adult walking ticket is around 6 GEL, with reduced rates for students and children. The optional underground boat ride costs extra, bringing the total to roughly 17 GEL. The cave is open daily from about 10:00 to 19:00, and the boat section runs only when the water level allows.

Why is Tsqaltubo famous for its sanatoriums?

Tsqaltubo was the Soviet Union's premier radon-carbonate spa town, where mineral springs stay at a constant 33-35 C. Dozens of grand sanatoriums and bathhouses were built between the 1930s and 1980s. Many now stand abandoned and have become a striking destination for photographers and urban-exploration travellers, while several are being restored as hotels.

Can you still bathe in the Tsqaltubo mineral springs?

Yes. Several working balneological centres and spa hotels in Tsqaltubo offer radon and mineral-water treatments, and the central Bathhouse No. 6 (Stalin's bath) area remains a focal point. Always confirm which baths are operating before you visit, as some buildings are closed or under renovation.

How long do you need for Tsqaltubo and Prometheus Cave?

A focused half-day covers Prometheus Cave plus a couple of sanatoriums. To also enjoy a spa treatment and nearby Sataplia, plan a full day, or stay overnight in Tsqaltubo or Kutaisi and combine it with Martvili and Okatse canyons.

Q: Is it safe to explore the abandoned sanatoriums?

Exterior photography is popular and generally fine, but many buildings are structurally unsafe and some still house displaced families. Be respectful, do not enter occupied or clearly dangerous structures, and consider a local guide who knows which sites are open to visitors.

TL;DR — quick answer. Tsqaltubo is Georgia's famous radon-spa town in the Imereti region, ringed by grand Soviet sanatoriums — some restored, many hauntingly abandoned. Just north lies Prometheus Cave, a 1.4 km lit walkway through 22 halls of stalactites with an optional underground boat ride (entry ~6 GEL walking, ~17 GEL with boat; open daily ~10:00–19:00). It is 9 km from Kutaisi and about 3.5 hours from Tbilisi. Easiest arrival: a fixed-price private transfer to Kutaisi and on to Tsqaltubo.

Why visit Tsqaltubo and Prometheus Cave

Few corners of Georgia mix faded grandeur and natural wonder as vividly as the Imereti countryside around Tsqaltubo. The town itself was the crown jewel of the Soviet spa network: a planned resort built around naturally radioactive radon-carbonate springs that flow at a steady, body-warm 33–35°C all year. Workers from across the USSR were sent here on medical vouchers, and the state poured money into monumental sanatoriums, colonnaded bathhouses and a circular central park. When the Soviet Union collapsed, the visitors stopped coming, and many of those palaces of rest were left to nature. Today their cracked staircases, overgrown atriums and peeling frescoes draw photographers and curious travellers from around the world, while a steady wave of renovation is turning several back into working hotels and spas.

A short drive north, the landscape turns underground. Prometheus Cave (also called Kumistavi Cave) is one of the largest and best-developed show caves in the Caucasus — a cool, dramatically lit world of stalactites, stalagmites and curtain formations, complete with an underground river you can float along by boat. Together, the spa town and the cave make one of the most rewarding day trips in western Georgia, and they pair naturally with the dinosaur footprints at Sataplia and the canyons of Martvili and Okatse nearby.

Prometheus Cave: what to expect in 2026

Prometheus Cave sits near the village of Kumistavi, about 20 minutes north of Tsqaltubo. The standard visit is a guided walk of roughly 1.4 km along paved, well-lit pathways through 22 enormous halls, descending to around 80 metres below the surface. Coloured lighting picks out the cave's six halls open to tourists, and the temperature stays at a constant, jacket-worthy 14°C even when it is 35°C outside — so bring a layer in summer.

Tickets, boat ride and hours

The basic walking ticket costs around 6 GEL for adults in 2026, with discounts for students and children and free entry for the youngest visitors. At the far end of the route you can choose an optional boat ride along the subterranean river, which brings the combined cost to roughly 17 GEL. The boat operates only when the water level and weather allow, so treat it as a bonus rather than a guarantee. The cave is open daily, generally from about 10:00 to 19:00, with the last entry roughly an hour before closing. Tours leave in groups every 20–30 minutes, and an English-speaking guide is usually available.

Practical tips

Wear closed shoes with grip — the paths can be damp. There are around 50 steps and gentle gradients, so it is moderately accessible but not ideal for those with serious mobility issues. Arrive early in summer to beat tour-bus crowds, and combine the cave with Sataplia (15 minutes away) for a fuller half-day underground.

Exploring the Tsqaltubo sanatoriums

The abandoned sanatoriums are Tsqaltubo's signature sight. Names like Sanatorium Medea, Metalurgi, Shakhtari (Miner's) and Iveria rise out of the greenery in various states of decay and restoration. Many feature soaring entrance halls, mosaic floors and Soviet murals, and several are slowly being reborn as hotels — so the scene changes year to year. Photography of the exteriors and accessible public areas is popular and generally tolerated, but it is essential to remember that some buildings still shelter families displaced by the conflicts of the 1990s. Treat the area as a lived-in place, not a film set: be quiet, ask before photographing people, and never force entry into closed or dangerous structures.

The working baths

If you want the spa experience the town was built for, head to one of the operating balneological centres. The central Bathhouse No. 6 — popularly linked to Stalin — anchors the spa quarter, and modern hotels offer radon and mineral baths and physiotherapy. Always confirm in advance which baths are open, as the line-up shifts with ongoing renovation.

How to get there

Tsqaltubo lies just 9 km from Kutaisi, Georgia's third city and home to Kutaisi International Airport (KUT), a major low-cost-airline hub. That makes the region very easy to reach. From Tbilisi it is about 250 km — roughly 3.5 hours by car along the E60 motorway. There is no direct public-transport route to Prometheus Cave, so most independent travellers take a train or marshrutka to Kutaisi and then a local taxi, which can mean a lot of waiting and negotiating.

For a smooth day, a fixed-price private transfer is hard to beat: your driver can collect you in Tbilisi, Batumi or at Kutaisi Airport, wait while you tour the cave and sanatoriums, and continue to Sataplia or back to the coast. With OrbiTrip the price is agreed upfront and you pay the driver directly — there is no commission and no prepayment. Travellers arriving on the Black Sea side often combine the cave with the Kutaisi to Batumi route.

When to visit

Prometheus Cave is a year-round destination thanks to its constant indoor temperature, but late spring through autumn is best for pairing it with the canyons and for comfortable walking around the sanatorium park. Summer brings crowds and heat above ground; winter is quiet and atmospheric. For a wider seasonal overview, see our guide to the best time to visit Georgia.
