Mount Orjen is a block mountain lifted up as a horst and thus towering above the lowered Bay of Kotor and the high karst plateaux surrounding the Mount Orjen horst. With 1894 m difference between the lowest and the highest point, relief energy has a great role in the extremely harsh environment. A hyperkarstic barren landscape of vast karren fields contrasts with very species rich vegetation types, ranging from evergreen deciduous forests at lower altitudes to endemic calcareous Dinaric Fir and Pine forests in higher altitudes. Precipitation reaches 5000 l per m², amounts typical for tropical rainforests or the eastern Himalayas than the dry Mediterranean. Lying at Europe's wettest coast, snow easily accumulates on karstic plateaux and as late as June small snow patches continue to lie in shaded places under the summits. Skiing is possible but no relevant infrastructures exist today. Orjen is a more important hiking destination. Three mountain huts provide basic accommodation.
