Prometheus Cave in Georgia: how to get there and what to know
Prometheus Cave (Kumistavi) is 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 there are six halls, an underground river, stalactites and stalagmites 60–70 million years old, and a boat route along the subterranean channel. A car is by far the easiest way to get here — and it's not only about the drive itself: with a rental you can easily fold the cave into one day together with Martvili Canyon, Sataplia Reserve or Kinchkha Waterfall.
What's inside: the short version
The visitor route through the cave is about 1.4 km long. You walk through six halls with names taken straight from Greek mythology: Argonauts, Colchis, Medea, Love, Prometheus and Iberian. The finale is a boat ride along the underground river Kumi (roughly 380 meters). The whole tour takes about 1–1.5 hours.
Inside it's a steady +14 °C all year round, whatever the season. In summer you really feel it: after a hot day the cave greets you like an air conditioner. Bring a light jacket — you won't regret it.
A few practical details:
- Photos are allowed, but only without flash and without a tripod
- Video is not permitted
- Children under 6 are not admitted
- Guides speak Georgian, Russian and English; Russian-language groups are put together from 10 people up

The boat is optional, and the route doesn't fall apart without it. But if the budget allows, take it: floating along an underground channel under coloured lights is one of those experiences you struggle to put into words afterwards.
Opening hours:

- September–October: 10:00–17:30
- November–April: 10:00–17:00
As of early 2026 the cave is open daily with no closing day — but do check the official site before you go: the schedule changes from time to time.
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, and from there the cave is a stone's throw away. From Tbilisi and Batumi a day trip is realistic if you set off early.
From Tbilisi
~250 km along the E60 via Gori and Kutaisi. By car — about 3.5–4 hours one way. That's a full day, especially if you're planning a canyon as well. The ideal version: rent a car in Tbilisi, leave at 7:00–8:00 in the morning, be at the cave by lunchtime, and afterwards drop by Martvili or Okatse.
By marshrutka: from Didube station to Kutaisi (about 3 hours, 15–20 GEL), then a marshrutka to Tskaltubo (30 minutes, 1 GEL) and one more to the cave (20 minutes, 1.5 GEL). That's 4–5 hours on the road and a hard dependency on timetables. Without a car it's tiring.
From Batumi
~140–155 km along the E60, about 2.5–3 hours by car. From Batumi the most convenient plan is to leave early in the morning and run the route Prometheus → Martvili → back. Or add Okatse Canyon — but then it becomes a tightly packed full day.
By marshrutka: from the bus station to Kutaisi (10 GEL, ~2.5 hours), then the same way via Tskaltubo.
From Kutaisi
The simplest option. ~20–22 km, about 30–40 minutes by car. If you're in Kutaisi, the cave is practically on the next street. If you flew in on a low-cost carrier, it's convenient to pick the car up right at Kutaisi airport: the cave is less than an hour from there. Taxi drivers from the centre charge roughly 25–40 GEL one way.
Why a rental car is the better call
Public transport to Prometheus officially exists, but it runs unevenly — especially the last stretch from Tskaltubo to the cave itself. Marshrutkas come once every one or two hours, and if you miss the one you needed, you can lose 1.5–2 hours just waiting. A taxi from Tskaltubo is a real alternative, but then you'll have to agree on the return trip in advance.
We've done it both ways — and with a car the day looks completely different:
- Leave when it suits you — not on the 7 AM marshrutka's schedule
- Stop at a good view along the way — the road through Imereti earns it
- Add a second stop — Martvili, Sataplia or Kinchkha — with no logistical pain
- Come back without transfers — straight to the hotel in Tbilisi or Batumi
The roads from Kutaisi to the cave are normal asphalt, no four-wheel drive needed. An ordinary sedan or hatchback will manage. A choice of cars across Georgia is on mydrive.club; more about renting — in the FAQ section.
What to combine nearby
If you're heading to Western Georgia anyway, it feels like a waste to spend the day on the cave alone (even though it's worth it). Here's what lies within a 1–1.5 hour drive:
- Martvili Canyon — boats on turquoise water between the cliffs. About 60 km from the cave.
- Okatse Canyon — a suspended walkway above the gorge. A similar kind of trail, ~30 km from Martvili.
- Sataplia Reserve — dinosaur footprints and a viewing platform above Kutaisi. 20 km from the cave.
- Kinchkha Waterfall — two-tiered, ~68 m high. Requires a short hike.
- Gelati Monastery — one of Georgia's main Orthodox shrines, 25 km from Kutaisi.
A sensible pairing for one day: Prometheus + Martvili (or Prometheus + Sataplia). Three stops in a single day is already pushing it, especially with kids.
Where the name came from
The name wasn't dreamed up by marketers. Mount Khvamli is clearly visible from the cave, and in the Caucasian version of the myth that's exactly where the gods chained Prometheus. In the Georgian version of the legend he's called Amirani — the local counterpart of Prometheus, stealing fire for people. The cave was discovered in 1984 by a speleological expedition. Research began before the collapse of the USSR, then everything was frozen for many years. It reopened for tourists only in 2011.
Only a small part has been explored so far: the visitor route is roughly 10% of the total length of the cave system. Beneath the Tskaltubo karst system there are another 20 km or so of underground passages that aren't open to the public yet.
Bottom line
Prometheus Cave is one of the few Georgian attractions that doesn't disappoint: huge, well equipped, genuinely impressive. It's worth the trip from any major city in the country, but the most convenient way is by rental car: that way you can add the neighbouring canyons and stop checking marshrutka timetables. From Tbilisi it's a full one-day route; from Batumi it's a little easier; from Kutaisi it's half an hour behind the wheel and you're there.
