Seoul is enveloped by mountains, consisting of Bugaksan, Namsan, Naksan, and Inwangsan to name a few major peaks surrounding the city. Bugaksan, the mountain located to the north of Seoul, is the highest among these and is a southern offshoot of Bukhansan Mountain. It is also referred to as Baegaksan. Seoul Fortress Wall runs along the mountain ridge and Changuimun (also called Jahamun), one of the four small gates surrounding the castle town during the Joseon Dynasty, is on the west side of the mountain near Inwangsan Mountain. Running between Changuimun and Arirang Hill in Jeongreung, Bugak Skyway is a scenic road overlooking downtown Seoul; it also passes through a variety of attractions such as Changuimun and Bugak Pavilion. Another attraction is Samcheong Park at the southern foot of Bugaksan Mountain. Inwangsan Mountain (to the west of Bugaksan) and Naksan (to the east) were considered ideal locations, according to the philosophy of Feng Shui. Known for its rugged granite, Inwangsan Mountain was the site of many tigers attacks during the founding of the Joseon Dynasty. According to legend, the king entreated the mountain deity to send the tigers across the Yalu River. Even though the tigers were banished from Inwangsan, one female tiger bearing babies was allowed to remain on the mountain. The babies, subsequently multiplied and made Inwangsan a feared place, full of tigers. Inwang Skyway connects the east of Inwangsan to Bugaksan. The eastern side of Inwangsan was turned into a posh residential area while Guksadang (literally "National Shrine") was moved from Namsan to an area west of the mountain in the 1920s. Even today, shamans perform exorcisms at the shrine, as well as rituals honoring the mountain deities.

Amsa-dong Prehistoric Settlement Site reproduces the lifestyle of the Neolithic Era (7000 B.C. ~ 1000 B.C.) Even the entrance gate shaped like a huge dolmen and the trashcans are ancient diagonal-line patterned earthenware. Amsa-dong Prehistoric Settlement Site was excavated in 1925 when a flood washed away the soil on the banks of the Hangang River and exposed a large number of diagonal-line patterned earthenware. After several excavations, the Amsa-dong Prehistoric Settlement Site was established.The site was a massive colony of primitives, thus many ancient buildings, stone axes and stone arrows have been uncovered as well as countless diagonal-line patterned earthenware. The housing site is round with a spot in the center for fire. The site is colossal and possesses nine mud huts, two exhibition halls displaying ancient artifacts and an open mud hut where you can experience life in the Neolithic Era. The site offers many attractions such as mud huts and promenades.

Igidae Park faces Jangsanbong Peak which is included in Yongho 3-dong. After passing one hill between Yongho Sewage Treatment Plants and Igidae, the east side where the peak (225.3 m high) can be seen has picturesque scenery, created by uniquely shaped rock cliffs, but it is too dangerous for tourists to visit. Therefore, visitors can take a ship in order to enjoy the scenery. The center of Igidae looks almost flat and seems to be leaning against the mountain which is linked to the sea for about 2km. The scenery including waves crashing into the rocks is fantastic and the area is also a suitable fishing spot. The area was used as a military operation area so civilian access was prohibited until 1993.

One of the amazing things about Seoul is that some of the most interesting historical sites are right in the middle of the business districts. Located near the Jongno Police Station and the Japanese Cultural Center, Unhyeongung Royal Residence is one such site. Unhyeongung Royal Residence was the home of young Gojong, who later became Emperor during the Joseon Dynasty. Under order of Queen Mother Jo, Unhyeongung was renovated into a grand, palace-like house with four gates. Gojong’s father, Yi Haeung, or better known as Heungseon Daewongun, continued to live at Unhyeongung for most of his life. Damaged during the Japanese colonial period and the Korean War, the Unhyeongung Royal Residence seen today is a much smaller version of the majestic structure that it used to be. Entering through the front gate, the first noticeable sight is a small row of rooms to the right. This area, called Sujiksa, housed the servants and guards. To the front, left-hand side of Sujiksa is a structure called Norakdang. Many important events, such as birthday parties and ceremonies, as well as the wedding ceremony for Gojong and Myeongseong, were held here. To this day, traditional wedding ceremonies continue to be held at Norakdang. Norakdang also served as one of the two women’s quarters. The most notable structure inside Norakdang is the kitchen, which was used for food preparation when hosting important events. Right outside Norakdang, there are several rock structures along the path to Irodang. The rock structures are said to resemble various animals. To the left of Norakdang lies Irodang, the main building of Unhyeongung. This was where the wife of Heungseon Daewongun resided. Irodang's most prominent feature is its tall steps and square shape. It was built this way in order to help protect the women inside from intruders. Outside Irodang lays an old well on one side of the wide, open yard. To the right of Norakdang lies Noandang. Noandang served as the men’s quarters and was where Heungseon Daewongun received his guests. The word noan means "old man" and carries with it the connotation of comfort and ease. Thus, it served as the leisure quarters for the men. However, Noandang was not just a place of rest and entertainment. As the father of a young Emperor, Heungseon Daewongun carried out all his business from Noandang. Upon exiting Noandang, there lies an Exhibition Hall to the far right. The Exhibition Hall houses a small collection of interesting artifacts and information. Items such as a scale model of Unhyeongung, writing tools, traditional wedding garments, and more, can be seen here. Next to the Exhibition Hall, there is also a small coffee shop and tea room where visitors can enjoy a nice beverage while taking in the sights of Unhyeongung.
