4. Russia’s Secret Ice Caves
In the far east of Russia, on a peninsula called Kamchatka, are stunningly surreal-looking ice caves that are formed under incredibly interesting conditions. Fire and ice are involved, or volcanoes and glaciers. As EPOD states about one, “It was formed by a stream flowing from the hot springs associated with the Mutnovsky volcano. This stream flows beneath glacial ice on the flanks of Mutnovsky. Because glaciers on Kamchatka volcanoes have been melting in recent years, the roof of this cave is now so thin that sunlight penetrates through it, eerily illuminating the icy structures within.”
Visitors get to see about 5.7km of the cave on 1½-hour tours; some 4km of this is covered by an electric train, which runs as far as the Big Mountain (Velika Gora) cavern. Here you stand under one of the five signs identifying your language, and a guide escorts you through halls, galleries and caverns. These are dry galleries, decorated with a vast array of white stalactites shaped like needles, enormous icicles and even fragile spaghetti. The stalagmites take familiar shapes – pears, cauliflower and sand castles – but there are also bizarre columns, pillars and translucent curtains that look like rashers of bacon
