The Valley of Geysers in Kamchatka is one of the largest geyser fields in the world and part of the UNESCO-listed Kronotsky Nature Reserve. The valley hosts over 40 geysers, hot springs, and boiling mud pools in a relatively small area of just 6 km long. Only accessible by helicopter, making the visit a unique adventure. Tours typically include three stops: the Valley itself, Uzon volcanic caldera with its colorful mineral lakes, and Nalychevo hot springs for bathing. The flight offers spectacular views of volcanic landscapes.
