Kamchatka Peninsula In Russia is the important peninsula. The Kamchatka Peninsula is a 1,250-kilometer long peninsula in the Russian Far East with an area of 472,300 square kilometers. It lies between the Pacific Ocean to the east and the Sea of Okhotsk to the west. The Kamchatka River and the surrounding central valley are flanked by large volcanic belts containing around 160 volcanoes, 29 of them still active. The highest volcano is Klyuchevskaya Sopka (4,750 m), the largest active volcano in the Northern Hemisphere. Kamchatka boasts diverse and abundant wildlife. This is due to climates ranging from temperate to subarctic, diverse topography and geography, many free-flowing rivers and proximity to highly productive waters from the northwestern Pacific Ocean and the Bering and Okhotsk Seas.
