It will be too much rush...this is a famous national park in Korea with so many trails to explore..traveling to and from Seoul with visit to park and sokcho beach will not give you any experience. Please stay 1 night in sokcho and visit beach and other sokcho sights next day..you can also go to a very nice naksansa temple near sokcho
Can we do the national park and beach in 1 day itinerary from Seoul?
