protected area of Russia
The Lena Pillars Nature Park is a 
UNESCO World Heritage Site in Yakutia, Russia.
The main attraction are the rock formations on the bank of Lena River — the Lena Pillars. They are made up of layers and different types of rock and minerals. These formations are 150-300 m high, and were formed in some of the Cambrian period sea-basins. The park has been a UNESCO World Heritage Site since 2012.
The park has a continental Siberian climate with lows down to -60°C in winter and heights up to 30°C in summer.
The nature park can be accessed from Yakutsk by river boat. The 180 km journey upstream (south) takes about a day.
There are few documented walking trails in the park, so advance planning is advised.
The most impressive rock formations can be found between the villages Petrovskoye and Tit-Ary.
