Ondal Cave is important and significant in terms of cultural value and tourism. In addition, there are abundant historical and cultural resources nearby. If the geographical strength is taken advantage of, the cave would evolve into a great tourist destination and natural education spot. This paper has investigated humanistic environment of Ondal Cave in considerations for the surrounding tourism resources. There are abundant tourism resources around Ondal Cave. However, they are rarely connected with each other. In fact, they are very partially interrelated around Guinsa(temple) only. Furthermore, the number of tourists has gradually decreased. Therefore, it‘s required to further develop tourism programs and surrounding tourism resources.

The Ondal cave, as limestone cave, located in 37$^{\circ}$ 03'N, 128$^{\circ}$ 29'E and in Ha-ri, Yongchun-myeon, Banyans-gun, Chungchongbuk-do. This study analyzed the groundwater of Ondal Cave with 44 items. On investigation almost of items were low and only germs were high than a base numerical value, this is supposedly caused by tourist entrance. For the better management of the Ondal cave the preventing is required.

온달동굴 내에 분포하는 관람대상 지형지물과 관람객의 이동통로에 설정 가능한 관람 포인트를 구축하고 이에 따른 네트워크구축사례와 네트워크의 특성 분석을 통한 온달굴의 관람포인트의 특성을 고찰하였다. 온달동굴의 관람루트는 정해진 루트를 이동하기 때문에 그래프상의 목(tree)형 형태를 갖는다. 관람포인트와 관람대상물의 관계를 통한 관람루트의 특성을 네트워크 분석기법을 이용하여 분석하였다. 온달동굴의 수치적 결과는 차후 유사한 동굴간의 관람루트를 비교 분석하거나 관람방식에서 생기는 문제점을 파악하는 기초자료로 제공 될 수 있다.

This paper is attempted to review a cave restoration and preservation plan against environmental destruction and pollution as a preliminary survey for preservation of cave environment. Consequently, it's important to throw an indirect light rather than direct light on cave formations, keeping distance of 2m at least. The already existing moss should be removed using wet cloth or sponge as soon as possible. If it's washed off, be careful not to splash it or water on nearby subjects. Based on an automatic switch-off system, light will automatically turn off when no one is left in the cave. It's also recommended to dualize the cave passage and partially close the cave by taking turns to give a time to recover.
