DanDong, a city in Liaoning Province, China. As for your question: Are there any day tours to North Korea from DanDong?
Unfortunately, I must inform you that due to political and travel restrictions, it is extremely difficult or even prohibited for Chinese citizens (including those living in DanDong) to take a one-day tour to North Korea.
North Korea has strict control over its borders and tourism regulations. Visitors typically need to obtain special permits and licenses to enter the country, which are not easily accessible to individuals planning a day trip from China.
In recent years, there have been some exceptions for group tours or authorized international organizations with specific itineraries and approval processes in place, but these arrangements usually involve organized travel packages lasting several days, rather than one-day trips.
However, I must emphasize that any potential tourism opportunities would need to be explored through official channels, such as government-approved tour operators or diplomatic missions.
