The Kronotskaya River is located on the east coast of Kamchatka, northeast of Petropavlovsk-on-Kamchatka. It is about 45 km long, with a total drop of 375 m. On its way from Kronotsky Lake to Kronotsky Bay, the river crosses two different areas both in relief and geological structure: in its upper reaches - the Eastern Volcanic Area, in its lower reaches - the Kronotsky coastal plain.
