The Gachedili Canyon was carved by erosive action of the Abasha River in the limestone rocks of the southern part of the Ashkah massif in the Odishi-Guria plain.
From the structural geology prospective it is evident that the fold was formed in Mesozoic and Paleocene sediments which are now exposed by canyon erosion.
Numerous remains of invertebrates, such as nautiloids, ammonites, brachiopods and sea urchins helped to determine geological epoch of these findings.
[8] The Gachedili Canyon limestone cliffs are surrounded by Euxine-Colchic deciduous forests with typical mixed flora, including yew, black alder (Alnus glutinosa), hornbeam (Carpinus betulus and C. orientalis), Oriental beech (Fagus orientalis), and sweet chestnut (Castanea sativa) together with evergreen Nordmann fir (Abies nordmanniana), Caucasian spruce (Picea orientalis) and Scots pine (Pinus sylvestris)[9] and many varieties of mosses and ferns.
Amphibians and reptiles include European green toad (Bufotes viridis), hylidae, dice snake (Natrix tessellata).
Visitors are also offered a boat trip through canyon on a 300 meter long section of the Abasha river.
Some accidents have occurred with daredevils jumping from waterfalls, swimmers in the high water, scuba diving without proper equipment or training and rappelling or spelunking activities.
