The Valley of Geysers and volcano Uzon caldera located in Kronotsky nature reserve in Kamchatka is a "favourite" place of many Russians to sacrifice their extremities touching the thermal springs with their fingers and wearing sandals despite all the instructions they get. They tread upon the green grass under which is the hot and chemically aggressive mud. After such experiments burns of the feet heal tortuously slow. It is worthy of note that ONLY Russians show such curiosity, other travellers prefer to follow precautionary measures.
But what about bears? They don't get instructions and the wood covering is not made for them. And they are always bare paws.
