Gyeongsangbuk and Gyeongsangnam
The Yeongnam cultural region is the birthplace of the Silla Kingdom, a thousand-year-old kingdom that left traces making the region particularly interesting to visit.
North Gyeongsang
First of all, if you like small isolated pieces of land, you can go to theUlleung Island. Although located off the coast of Donghae (150 km from the coast), this small island (less than 10 km by 10 km on each side), is part of the province of North Gyeongsang and not of Gangwon. Dominated by the Seonginbong Mountain, which allows for some nice forest hikes, you also have at least one waterfall and viewpoints of the steep cliffs surrounding Ulleung.
Focusing back on the continent, we find two of the seven mountain temples, included in the Sansa recorded in Unesco World Heritage. There is the Buseoksa Temple, north of Yeongju and that of Bongjeongsa, northwest of Andong.
There is also one of the nine Korean Neo-Confucian academies, which are called Seowon and also listed as UNESCO World Heritage Sites which I definitely write about a lot. In this province, there are four of them, Oksan-seowon, west of Pohang and the trio Dosanseowon, Byeongsan-seowon, Sosu-seowon, still around Andong.
And justly, Andong can be an interesting stop, just like we went there. If we did not visit its pedestrian bridge (Woryeonggyo Bridge), the longest bridge (387 m) of its kind in South Korea, spanning the Nakdong River, Andong served as our base for visiting the photogenic and other UNESCO-listed site, the Hahoe Folk Village. The area is also known for its folklore around traditional dances involving masks, which we witnessed in the village. Andong is also known for its local rice alcohol, Soju, which we tasted at the Andong market.

The must-see stop in North Gyeongsang is the Gyeongju city, a true open-air museum which includes several sites listed in the Unesco World Heritage. We thus find the combo Seokguram Cave and Bulguksa Temple, located close to each other, outside the city. The historic areas of Gyeongju as a whole are also included in the "properties" registered by UNESCO. They include the Joseon Dynasty royal tombs which dot the area, the former astronomical observatory of Cheomseongdae et Wolji Pond and Donggung Palace Ruins.
Near Gyeongju, to the north, is another old village, similar to Hahoe and also a UNESCO World Heritage Site, the Yangdong "clan" village.
Just to the south is the Gyeongju National Park, which includes the Namsan Mountain (not to be confused with the hill where the N Seoul Tower is located). In addition to being a great place for hiking, you will find some remains of the Silla kingdom, mainly small stone pagodas and Buddha sculptures.
Northwest of Daegu, next to the small town of Gumi, is a local attraction, the Yagsaam temple (also spelled Yaksaam or Yaksa-am), literally clinging to the side of the mountain which is part of the Geumosan Provincial Park.
Finally, “honorable” mention for the Mungyeong City, which concentrates some interesting attractions. To the north, you have the old ramparts, and a site that was rebuilt to serve as a setting for historical TV series (at Mungyeong saejae open the set), never mind. To the south, you will have several swimming spots in the river and hiking towards the Mount Daeyasan.
South Gyeongsang
Its main attraction lies in the Jirisan National Park, home to beautiful scenery (and Asian black bears), close to the city of Jinju. With the province extending all the way down to the seaside, in the far south, you can visit Geoje Island, considered suitable for romantic getaways. Off the coast of the latter is the small island of Oedo, known for its botanical garden covering almost the entire area.
It is also in this province that another of the seven Sansa temples is located, the Tongdosa, west of Ulsan. If you go west of Daegu, you have an important temple in the middle of the mountain of Gayasan National Park, Haeinsa Temple (which you can reach via the locality of Goryeong). Another notable temple if you haven't had your fill, the Tripitaka Koreana, which you can visit right away since it is located just a few hundred meters from Haeinsa. The latter being listed in UNESCO World Heritage Site.
If you like the charm of old villages, you can go to Namsa Yedamchon Village, northeast of Yeosu, close to the southern coast.
Daegu
Also spelled Taegu, it is the main city in the region, which can serve as a base for visiting the surrounding area. It is known for its tower, the E · WORLD 83 Tower, taller than the N Seoul Tower, with its 312 m. Without having to climb this tower, you can dominate the city from the Apsan Park.
Daegu is also known for its large Seomun Market, the largest traditional street market, bringing together no fewer than 4 stores.
Ulsan
Ulsan is a port city in the southeast of South Korea, overlooking the Sea of Japan. It has a few colorful streets, a large beach (Ilsan Beach) and a series of parks along the Taehwa River, including the Taehwagang National Garden. And if you like flowers, you also have the Ulsan Grand Park, at the foot of one of the hills surrounding the city. On another, you will have a viewpoint over the city, at a place called Hamwollu.
Busan
We arrive at Busan, also spelled Pusan. The famous seaside city in the southeast of South Korea. This is where we visited another site, Unesco World Heritage, the photogenic seaside temple, Haedong Yonggungsa, built in the 14th century. Its main beach, Gwangalli, sometimes brings together surfers with the Gwangwan Bridge in the background. People come to relax on its Haeundae Beach, where a sand sculpture festival takes place every year, which we were lucky enough to attend (the Busan Sands Festival is very popular in Korea).

At the Jagalchi fish market in Busan.
Close to the port and its Jagalchi fish market, there is a shopping area with street food, around BIFF square and Gukje market. And not far away is the BusanTower, yes, because Korea loves towers. Finally, one of the main attractions of Busan being Gamcheon Culture Village, a neighborhood with colorful houses built against the hills. It has become a tourist attraction by adding color to its steep streets, nice cafes and restaurants and an artistic side to the whole that make it an interesting half-day stroll.
The only visit we didn't make, due to the rotten weather, was the Taejongdae Natural Park, located at the end of Yeongdo-gu IslandIt is possible to take a walk along the cliffs, with a very beautiful view of the island.
