Marado, the southernmost point of South Korea, is the island the cast of Infinite Challenge spent 26 hours traveling to — all for a single bowl of jjajangmyeon. Ever since that special, 'Marado jjajangmyeon' has become a symbol of the island.
Marado is reached by ferry from Unjin or Moseulpo Port near Songaksan on the south of Jeju. You can walk the whole island in about an hour; the southernmost-point monument, the lighthouse and the jjajangmyeon restaurants are the key photo stops.
The ferries are sensitive to wind and often cancelled, so plan it loosely together with Moseulpo and Songaksan.
Please re-check opening hours and access on official channels before visiting.
