This area is bordered on the north by Ichon in Kyeongki province, on the northwest by Anseong in Kyeongki province, on the east by Chungju, on the south by Koisan-kun, and on the west by Jincheon-kun. There are hill areas in the northwest. With a great volume of water and rich soils, this area is a well-known agricultural region.
There is a part of the Sobaek mountain range including Mt. Kaseop (710m), Mt. Buyong (644m), Mt. Suri (505m), Mt. Weontong (520m) and Mt. Okap (609m) encircling the village. The natural ecosystem is relatively well preserved in those mountains, which is a favorite place of mountain climbers.

The central inland area has a similar climate as the surrounding areas, which have four distinctive seasons with a yearly mean temperature of 11.2¨¬C and a yearly mean precipitation of 1,360mm.
As compared with the surrounding areas, it has a lot of snow as the old name of the area Seolseong (Snow Castle) indicates.

Housing and Population
Eumseong-kun was a typical agricultural area in which houses were mostly detached. Industrialization started in 1987 and resulted in making major changes in the pattern of living by increasing the number of apartments and duplexes. Currently, the residential sites of Eup and Myeon are largely occupied by newly built apartment complexes and other residential types. The population reached its highest point of 127,007 in 1965, but gradually declined over the following 25 years to reach its lowest point of 74,717 in 1990. Since then, it has gradually but steadily increased as a consequence of industrialization. With its active development, Eumseong-kun is now the only area in the province where the population is increasing.

Eumseong-kun produces a lot of quality agricultural specialties with its rich soil and great volume of water. In particularly, clean red pepper, Ginseng, Mibaek peaches, watermelons, melons, grapes and apples are nationally recognized for their quality. Agricultural competitiveness has been raised by the introduction of organic farming and a high-tech facility to produce non-polluting agricultural products. With the opening of the Jungbu Expressway in 1987, this area was highlighted as an industrial district. 875 companies were registered as of 1998. In Chungbuk province, the largest numbers of companies are located in Eumseong-kun. When the development plans for the local industrial complex are completed, this area will be a core industrial region in the central zone so it will be an ideal place combining agriculture with industry.

The Jungbu Expressway passes through the northwestern part, the Jungbu Inland Expressway is under construction, and the Dongseo Expressway is being planned. The double tracked Chungbuk Railway passes through Weonnam-myeon and Soi-myeon in Eumseong-eup. The No. 36 National Highway (Cheongju - Chungju) has been widened into a 4-lane road while the No. 3 National Highway (Chungju - Seoul) is being extended into a 4-lane road. Such a traffic network accessible from all directions is the main driving force for the development of the local economy.
Tourist attractions include the Mukeuk Tourist Resort that was the first battlefield on which the North Korean communist forces were defeated during the Korean War. Also there is the Three Brothers Reservoir in Keumwang-eup and plenty of other reservoirs in which many anglers enjoy fishing. This area has the advantage of being close to the tourist attractions including Hwayangdong in Koisan, Lake Chungju and the hot spring resorts in Suanbo and Angseong.
