Prometheus Cave in Georgia: how to get there and what to know
Prometheus Cave (Kumistavi) — the largest karst cave in Georgia. Distances from Tbilisi, Batumi, and Kutaisi, 2026 prices, and the route by rental car.
Prometheus Cave (Kumistavi) is the largest karst cave in Georgia, 22 km from Kutaisi in the village of Kumistavi. Inside: six halls, an underground river, stalactites and stalagmites 60–70 million years old, and a boat ride along a subterranean channel. A car is by far the most convenient way in — and renting one gives you the most flexibility, letting you combine the cave with Martvili Canyon, Sataplia Reserve, or Kinchkha Waterfall in a single day.
What's inside: the short version
The tourist route through the cave is about 1.4 km long. You walk through six halls named straight out of Greek mythology: Argonauts, Colchis, Medea, Love, Prometheus, and Iberian. The finale is a boat ride along the Kumi underground river (about 380 meters). The full visit takes around 1–1.5 hours.
Inside it's a steady +14 °C year-round, regardless of season. You feel it in summer — on a hot Tbilisi day the cave hits like a walk into air conditioning. Bring a light jacket; you won't regret it.
A few practicalities:
- Photos are allowed, but no flash and no tripods
- Video is not allowed
- Children under 6 are not admitted
- Guides speak Georgian, Russian, and English; English groups need ~10 people to depart

The boat is optional, but if the budget allows it's worth it: drifting along an underground river under colored lights is one of those things that's hard to do justice in words.

As of early 2026 the cave is open daily — but check the official site before you go, schedules can change.
How to get there: from Tbilisi, Batumi, and Kutaisi
The cave sits in the Tskaltubo municipality in the Imereti region. The nearest large city is Kutaisi, practically next door. From Tbilisi and Batumi a day trip is realistic if you start early.
From Tbilisi
~250 km along the E60 highway via Gori and Kutaisi. By car — about 3.5–4 hours one way. This is a full day, especially if you're adding a canyon. The clean version: rent a car in Tbilisi, leave at 7–8 AM, reach the cave by lunchtime, then add Martvili or Okatse on the way back.
By marshrutka: from Didube station to Kutaisi (~3 hours, 15–20 GEL), then a marshrutka to Tskaltubo (30 minutes, 1 GEL), and another one to the cave (20 minutes, 1.5 GEL). Total — 4–5 hours of travel each way and a hard dependency on schedules. Painful without a car.
From Batumi
~140–155 km along the E60, about 2.5–3 hours by car. From Batumi the natural play is to leave early and run Prometheus → Martvili → return. Or add Okatse Canyon — that turns it into a packed full day.
By marshrutka: from the bus station to Kutaisi (10 GEL, ~2.5 hours), then the same chain via Tskaltubo.
From Kutaisi
The easy option. ~20–22 km, about 30–40 minutes by car. From Kutaisi the cave is essentially around the corner. Taxis from the center charge roughly 25–40 GEL one way.
Why a rental car is the better play
Public transport to Prometheus officially exists but runs unevenly — especially the last leg from Tskaltubo to the cave itself. Marshrutkas come every one to two hours; miss the right one and you can lose 1.5–2 hours just waiting. A taxi from Tskaltubo is a real alternative, but you'll need to negotiate the return ahead of time.
With a rental car everything changes:
- Leave when it suits you — not when the 7 AM marshrutka leaves
- Stop at a viewpoint along the way — the road through Imereti deserves it
- Add a second site — Martvili, Sataplia, or Kinchkha — with no logistics headaches
- Return in one go — straight to your hotel in Tbilisi or Batumi
The roads from Kutaisi to the cave are normal paved asphalt, no 4WD needed. A regular sedan or hatchback handles it. More on how renting works — in the FAQ.
What to combine nearby
If you're going to western Georgia, it's a shame to spend a whole day on the cave alone (worth it as it is). Within a 1–1.5 hour drive:
- Martvili Canyon — boats on turquoise water through narrow cliffs. About 60 km from the cave.
- Okatse Canyon — a hanging walkway above the gorge. Similar in spirit, ~30 km from Martvili.
- Sataplia Reserve — dinosaur footprints and a viewpoint over Kutaisi. 20 km from the cave.
- Kinchkha Waterfall — a two-tier fall about 68 m tall. Short hike required.
- Gelati Monastery — one of Georgia's most important Orthodox sites, 25 km from Kutaisi.
A reasonable day pairing: Prometheus + Martvili, or Prometheus + Sataplia. Three sites in one day pushes it, especially with kids.

Where the name comes from
The name isn't marketing. Mount Khvamli is clearly visible from the cave, and in the Caucasian version of the myth that's where the gods chained Prometheus. In the Georgian version of the legend he's called Amirani — the local equivalent who steals fire for humanity. The cave was discovered in 1984 by a speleological expedition. Some research started before the Soviet collapse, then everything froze for years. It only opened to tourists in 2011.
Only a small fraction has been mapped: the tourist route is roughly 10% of the full cave system. Beneath the Tskaltubo karst system there are another ~20 km of underground passages, not yet open to the public.
Bottom line
Prometheus Cave is one of those Georgian sights that actually delivers on the hype: huge, well-developed, genuinely impressive. Worth the drive from any major city, but most flexibly done with a rental car so you can stack on neighboring canyons and skip the marshrutka roulette. From Tbilisi it's a full day trip; from Batumi it's a bit easier; from Kutaisi it's a 40-minute round trip.
