You step out of the van and the air changes—cool, damp cave breath to one side, and the green hush of a river-carved gorge to the other. On a single private day trip from Tbilisi you move from the illuminated halls of Prometheus Cave into Martvili Canyon, a sharp contrast between underground caverns and a sunlit river running daringly between sheer limestone walls.
Verified experiences and guided adventures in the surrounding area.

You step out of the van and the air changes—cool, damp cave breath to one side, and the green hush of a river-carved gorge to the other. On a single private day trip from Tbilisi you move from the illuminated halls of Prometheus Cave into Martvili Canyon, a sharp contrast between underground caverns and a sunlit river running daringly between sheer limestone walls.
Prometheus Cave (Kumistavi) is a karst system cutting through Imereti’s limestone; roughly 11 km long, about 1,060 m are open to visitors across multiple chambers lit to show stalactites, stalagmites and flowstone. Martvili Canyon formed where the Abasha River sliced into the rock, leaving emerald pools and small waterfalls accessible by short walks and a guided boat ride that threads between high cliffs. The area also touches Tskaltubo’s Soviet-era spa culture—concrete bathhouses and spa history remain nearby.
Expect a mix of flat, paved cave walkways and uneven canyon steps; the boat section is calm but requires stepping in and out carefully. Plan for a long day—pick-up in Tbilisi makes this a 10–12 hour excursion. Bring a lightweight waterproof layer, non-slip footwear, and a camera with a lens cloth—the cave and canyon are wet places. Hydrate before the boat leg and leave single-use plastics behind; fragile karst and river ecosystems are sensitive to trash and trampling.
Timing matters: mornings often yield calmer water and fewer crowds in the cave. With a private guide and transport, the day is efficient—history, geology and a short, scenic boat ride stitched together for a full yet manageable Georgian nature day.
moderate.
10–12 hours.
Good general fitness for short hikes, stairs and multiple transfers; able to step on/off a small boat.
The private excursion runs about 10–12 hours with hotel pick-up in Tbilisi and return drop-off included.
Admission to Prometheus Cave and the Martvili Canyon boat ride are typically covered by the tour; confirm on booking for exact inclusions.
Children can join but must be accompanied by an adult; infant seats for the vehicle are available—check with the operator for boat safety for very young kids.
Yes—photography is allowed but avoid flash on sensitive formations and secure cameras on the boat to prevent drops.
The region’s karst features formed as water dissolved Imereti’s limestone over millennia; Tskaltubo later became a Soviet spa destination, leaving distinctive architecture near the cave.
Karst caves and river canyons are sensitive—stick to paths, avoid touching speleothems, and take all trash out to minimize human impact.
Journey to Georgia operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
