A visitor walking from the Beomeosa Gregarious Wisteria Habitat along Beomeocheon Stream will find a spectacular heap of rocks extending from Geumgangam Hermitage to the North Gate of Geumjeongsanseong Fortress. This area, called Dolbada (" Sea of Rocks" ), is 70m wide and 2.5km long. It was formed by the natural process of water freezing and melting repeatedly in nearby chasms. The murmuring sound of water flowing to down Daeseongam Hermitage was thought to inspire religious faith, and it is regarded as one of the Eight Scenic Views of Geumjeong, and has the special name of Daeseong Eunsu (" Silver Water of Daeseong").

These are the tombs of King Adalla (r. 154-184), King Sindeok (r. 912-917), and his son King Gyeongmyeong (r. 917-924), the 8th, 53rd, and 54th rulers, respectively, of the Silla kingdom (57 BCE-935 CE). They are all descendants of the Bak Clan. King Adalla worked to improve domestic affairs, such as by constructing roads, and also exchanged envoys with Japan in the year 173. Kings Sindeok and Gyeongmyeong reigned during the decline of Silla. They ruled only over the Gyeongju area, as the Later Baekje and Later Goguryeo kingdoms had already taken over most of the Silla territory. The tombs, from front to back, belong to Gyeongmyeong, Sindeok, and Adalla. The tomb of King Sindeok was robbed in 1963. The walls inside the stone chamber in the tomb mound were painted like a folding screen painting.

Beautiful views up there. Easy to reach, just take bus 7 or 7-1 from Sokcho and disembark on the very last stop. The route does not require any special equipment as it's mostly gravel and stairs (with handrail). Leave your poles at home, even sturdy mountain shoes are not particularly necessary. The last part is quite steep, so bring decent fitness. I did this trail in summer which can be very warm. We came early (the first bus from Sokcho runs at ~6.30) and the ascent was in the shadow mostly. Would not recommend to come later in the day as the sun will roast you. As everywhere in Korea, there's an abundance of toilets, the last one before the ascent is clearly marked as such.

What you should know about Seoraksan National Park is that the hike to Geumgangul Cave is really beautiful and challenging, as it goes very steeply uphill on rocks and stone steps. Shortly before the end, however, you can only reach the cave via a staircase mounted on the outside of the rock. Unfortunately, I had to pass on that. You do have to be able to handle a bit of height here. The same applies to the hike to Ulsanbawi Rock. On weekends and in autumn, it is more than full. Today, Sunday 10/20/24, we hiked to Ulsanbawi Rock in single file, which somewhat spoils the fun. But Seoraksan National Park is great and if you hike the main routes, you have to be prepared for there to be a lot of other hikers with you at peak times. But this is a good opportunity to immerse yourself in Korean hiking culture.

Towangseongpopo usually does not have a lot of water, so it is difficult to appreciate the water flow with the naked eye from the observatory, but after heavy rain, it creates a spectacular sight. The slope is relatively gentle up to Biryong Falls, but the steep slope continues from there until the Towangseong Falls Observatory.

Water was drinkable and a nice cool down at this hot day. But check the paperwork from the council next to it before drinking it!
