Tsar Gate

Imagine a huge donut stuck in the ground to its middle, add a challenging even for an experienced rider trail and you'll be shocked as I was when I saw this beauty. This rock formation is well known, but unreachable for most tourists (25 km of bad taiga roads from the nearest railway station, almost 1000 meters of uphills). Yet this place is still almost intact.
