Among them is Ryongmun Cavern famous for its underground scenery.

The cavern, located in Kujang County of North Phyongan Province, is a rare natural one formed by the action of solution and corrosion on the limestone layer for a long time.

It is the biggest one among the limestone caverns in the country and has two main caves and more than 30 side caves.

In the carven, there are dozens of mysterious spots showing stone flowers, stalagmites and stalactites of different shapes.

What catches the eyes of visitors is a waterfall called Samsonam with the height of 30 meters.

Last year, the cavern was remodeled.

Thanks to the detailed guidance of Chairman Kim Jong Il, it could be turned into a famous tourist resort and a precious cultural wealth of the country.

Visiting the cavern in March Juche 85 (1996), the Chairman indicated the principles, orientation and ways for its development and management ranging from the confirmation of beauty spots to their preservation and the organization of visits.

After then, he gave important teachings on the cavern scores of times, energetically guiding the work to turn it into a resort for the people.

Over the past 25 years, the cavern has been visited by a large number of people, including overseas compatriots and foreigners.
