We stayed very close to Sokcho beach and we can definitely recommend this to anyone. Staying here will have two major advantages. First of all, you are very close to Sokcho Express Bus Terminal which is great as you can simply walk from and to the Express Bus terminal on the day of your arrival and departure. Second of all you are close to the beach, which is a great place to relax after your hike inside Seoraksan National Park and also a great place to spend the evening.
With that said, we stayed at the Sokcho Chonpines Beach Hotel*, which is located only one street away from the beach! The hotel room was super clean and was well worth the money. All in all we really enjoyed our stay here and can definitely recommend this hotel to anyone! We paid around 50.000 KR₩ (35€, £30, 38$) per night.
