Maly Semyachik

Maly Semyachik is a stratovolcano on the Kamchatka Peninsula made up of three connected cone structures. The Troitsky Crater on the southwestern side holds a large turquoise lake that stands out against the volcanic slopes.

Around 17,000 years ago, a major eruption transformed the original volcano into a vast caldera. The three cone structures visible today formed during this geological shift.

The name comes from the Itelmen language and reflects how indigenous peoples understood this landscape. Local knowledge still treats the area as a place of significance in regional tradition.

Access requires special permits and guided tours due to the remote location and difficult terrain. Visitors should prepare for harsh weather and physically demanding hiking conditions.

The crater lake remains liquid throughout the entire year despite being in an arctic region, because its high acid content keeps the water at temperatures between 30 and 40 degrees Celsius. This year-round thaw is rare in such extreme climates.
