Hallim Park(한림공원) is located in the northeast of Jejudo island. So if it is first day of your tour after Hallim Park you can try sunset in the beach. You can see beautiful garden of four seasons, small folk village and cave. It is total 100,000pyeong(330,000 square meters). 

It had started in 1970s to develop the Park. In 1970s, it was best place for honeymoon for the Korean couple. Nowadays, it is also famous place for international tourists and the couple who has memories in their honeymoon.

Baekrokdam(백록담)is the dummit of Mt. Hallasan in Jejudo island(=Jeju island).  It makes beautiful scenery according to the seasons. In my opinion the most beautiful season is the winter.  

It is 1950 meter high, so you can see the summit every almost where from Jejudo island. It is the highest mountain in South Korea. It is connecting the Baekdusam mountain in the North Korea. We Korean calls it Baekdudaegan. 

Eventhough you don't go to the summit Mt. Hallasan is good place to enjoy manu oreum.

This trail starts at Hallasan National Park Visitor Center and continues of to Eoseungtaeng-oreum Summit. The trail is 1.3km long and a one-way trip takes 30 minutes. Eoseungsaengak is an oreum (parasitic cone volcano) for hikers who want to go for an easy stroll after visiting the Visitor Center. On clear days Chuja Island, Biyang Island, Seongsan-Ilchulbong and Jeju Island’s east oreums can be seen. At the summit there still remain some Tochikas, which were military facilities used by the Japanese during the occupation of Korea.
