|2350 Koryaksky volcano in Kamchatka|
The Kamchatka River and the surrounding central side valley are flanked by large volcanic belts containing around 160 volcanoes, 29 of them still active. This is one of the most outstanding volcanic regions in the world, with a high density of active volcanoes, a variety of types, and a wide range of related features. 29 active volcanoes, grouped in six sites, were included among UNESCO World Heritage Sites. The sites contain also great species diversity, including the world's largest variety of salmonoid fish and exceptional concentrations of sea otter, brown bear and Stellar's sea eagle.
The highest volcano is Klyuchevskaya Sopka (4,750m), while the most striking is Kronotsky, whose perfect cone was said to be a prime candidate for the world's most beautiful volcano. Somewhat more accessible are the three volcanoes visible from Petropavlovsk-Kamchatsky: Koryaksky, Avachinsky, and Kozelsky (from Avachinskaya group). Koryaksky or Koryakskaya Sopka (3,456m), has been designated, together with neighbouring Avachinsky, a Decade Volcano, worthy of particular study in light of its history of explosive eruptions and proximity to populated areas.
