Martvili Canyon carves through Cretaceous limestone in a series of waterfalls and emerald pools that have flowed for six million years. The Abasha River drops twelve metres through the gorge in a sequence that exposes fossilised marine sediments from when the Caucasus lay beneath the Tethys Sea. Upstream, dinosaur footprints from the Early Cretaceous remain visible in the bedrock during low water months — Ornithopod tracks that predate the canyon itself by eighty million years. Prometheus Cave extends 11 kilometres beneath the Imereti plateau, though only 1.4 kilometres are accessible to visitors along an illuminated concrete walkway installed in 2011. The cavern system formed during the Pliocene as carbonic acid dissolved the Jurassic limestone, creating six distinct halls with stalactites, helictites, and petrified waterfalls. The cave maintains a constant 14°C year-round, its chambers named after mythological figures — a nod to the Greek legend that placed the Titan's punishment in the Caucasus range. Geological surveys confirm the cave continues far beyond the tourist route, with unexplored passages extending beneath the Sataplia Nature Reserve. Okatse Canyon runs for sixteen kilometres along the Okatse River, its sheer walls rising 50 metres above the watercourse. A steel walkway built in 2014 extends 780 metres along the canyon's northern rim, terminating at a glass-bottomed platform suspended above the river. The gorge cuts through the same limestone strata as Martvili, but the Okatse's higher flow rate has carved a narrower, deeper channel. In the upper reaches, the river cascades over a 15-metre fall before entering the main canyon. The three sites form a geological transect through western Georgia's karst landscape, each shaped by water acting on sedimentary rock over epochs. Private canyon cave tour from batumi(martvili okatse prometheus) itineraries link them in a single route, covering roughly 200 kilometres through the Samegrelo-Zemo Svaneti and Imereti regions. The distance between Martvili and Prometheus Cave measures 45 kilometres; Okatse lies another 20 kilometres northeast. Most tours originate in Batumi or Kutaisi, with transport provided in climate-controlled vehicles. Entrance to each site requires separate admission, managed by the Agency of Protected Areas under Georgia's Ministry of Environmental Protection.
