Sarabong Suteo is a historical site on Sarabong in Jeju where you can see a Joseon-era beacon mound and a Japanese colonial period cave. From the summit, you look down on Jeju International Airport and Jeju Passenger Terminal, and an octagonal pavilion offers a view of the sea. A parking lot sits directly in front of the entrance, and the round trip takes under an hour. Cherry blossoms bloom around the summit, and the Jeju nightscape is visible there.
