Jeju Island has decided to upgrade its social distancing to level 4 for two weeks from on the 18th Aug.
All 12 designated beaches in Jeju Island will be closed during this period due to the upgrade of level 4.
Private gatherings are allowed for up to four people before 6 p.m. and up to two people after that.
All other quarantine rules also apply to the same standards as the metropolitan area where Phase 4 is in effect.
It seems to be a measure due to a steady stream of tourists visiting Jeju Island, and in fact, it should be considered a rock-down.
