Baeron Holy Ground
 
Chungcheongbuk-do(Jecheon-si) ,
Located along the national highway between Jecheon and Wonju, Baeron Holy Ground has great spiritual significance as it served as the fountainhead of the spread of Catholicism in Korea. During the early years of Catholicism in Korea, Catholics fleeing from the Sinhae Persecution (1791) came to this place, formed a community, and made their faith deeper. A man named Hwang Sa-yeong (Alexander, 1775–1801) hid in a tunnel and wrote letters about the situation of the Joseon Catholic Church on silk fabrics, but was captured and martyred in 1801. Baeron is a historic place where Joseon’s first theological school, St. Joseph Theological School, was founded, but the school was eventually shut down. The graves of Fr. Tomas Choe Yang-eop (1821–1861), Korea’s second Roman Catholic priest, and the Martyr Hwang Sa-yeong Memorial Tower can be seen at Baeron Holy Ground. Baeron Holy Ground is surrounded by rugged mountains such as Guhaksan Mountain and Baegunsan Mountain and Chiaksan Mountain. The mountain path from the holy ground eventually leads to Bakdaljae Natural Forest.

Seoraksan National Park (NaeSeorak; Inner Seorak)
 
Gangwon-do(Inje-gun) ,
Also referred to as Seolsan and Seolbongsan, the mountain was named Seorak ('Seol' meaning 'snow' and 'Ak' meaning 'big mountain') because the snow would not melt for a long time keeping the rocks in a permanent state of white. In November 1965, the Seorak Mountain district was designated as a Natural Monument preservation area. Afterwards in December 1973, it was designated as a park preservation area, and in August 1982, as a Biosphere Preservation District by UNESCO.The park is spread across 4 cities and counties: Sokcho, Inje, Goseong and Yangyang. The highest peak is Daecheongbong; to the east is OeSeorak and to the west is NaeSeorak, which is divided again into North NaeSeorak and South NaeSeorak. North NaeSeorak is composed of Bukcheon, which flows to Ingyecheon and Baekdamcheon streams. There are numerous valleys in NaeSeorak. Follow the Baekdamcheon Valley where all the streams meet and you will reach Baekdamsa Temple, which is known for its beautiful scenery. Upstream there is Gayadong Valley and Suryeomdong Valley, and past Yeongsiam and Mangyeongdae there is Madeungryeong Ridge (1,327m) that leads to Seorakdong.Follow Suryeomdong Valley and you will reach Waryong and Ssangpok waterfalls . Further up is Bongjeongam (1,224m sea level). Once you arrive at Daecheong Peak you can view the magnificent mountain range. The sunrise viewed from here is spectacular and should not be missed. South NaeSeorak directs the valley from Oknyeotang area to Hangyeryeong. Daeseung Waterfall north of Jangsudae is the most beautiful site of NaeSeorak, which is 88m high. South of Yongdaeri Valley is the Twelve Fairy Bathing Spring, Oktang Falls, and Yongtang Falls, along with several other traditional relics.

Changnyeong Upo Wetland
 
Gyeongsangnam-do(Changnyeong-gun) ,
There are four large and small swamps around the Yibang-myeon, Daehap-myeon, and Daeji-myeon areas of Changnyeong-gun, which are collectively called ‘Upo Wetland’. They are the largest natural swamps in South Korea, with a total size about 5,550 square km. The bottom of the swamp is shallower than 1m and there are over 1,000 species living in its murky waters. It has a primitive atmosphere with 100 kinds of plants containing 28 kinds of aquatic plants and 72 types of hydrophytes.Upo Wetland is a primitive low bed wetland, which was created about 140 million years ago. When soft ground collapsed, water started to come to a low basin, and this was a lake where dinosaurs lived 100 million years ago. Upo Wetland was formed in with the sediments from the mountains brought in by rivers. From the outer edge, the current Upo Wetland is going through natural alteration and ecological succession from a lake to swamp and from grass-covered plain to a forest. At Upo Wetland there are eight famous sites such as fireflies, constellation gazing, and willow groves, but there are many, many other interesting things to see. Among the eight famous sights, the Upo rain-fog is an especially eye-catching natural phenomenon, becoming visible when there is no wind, when skies are clear, and the temperature difference between day and night is 10 degrees or more. The fireflies come out around 8~9 P.M. in August and September, and they are also worth watching. In winter, migrating birds spend their winter here and you can watch about 33 species of birds such as swans, whopper swans, bean geese, teals and wild ducks. It is better to take a walk in the evening or early in the morning rather than in the daytime, it would be great also to visit in the night under the starlight.
