💡 Reserve ahead; the weekday lunch set is the affordable way in.
What you can’t visit
The North Korean village — Jeong-hyeok’s house, the communal courtyard — was a purpose-built open set in Taean-gun that was demolished after filming. And the Switzerland scenes (Sigriswil bridge, Iseltwald lakeside) are, of course, in Switzerland; interestingly, the Hantan River Sky Bridge above is the Korean stand-in the show itself connects to the Sigriswil one.
Building a CLOY day
The two Seoul spots (Ewha chicken shop, Cheongdam steakhouse) fold into any city day. Byeolmaro and the Sky Bridge are separate half-day trips in opposite directions — Yeongwol southeast, Pocheon northeast — so plan them as two different days rather than one long one. The Incheon beach works best as a send-off stop before an evening flight.
