The name is composed of the following terms, "Soe", meaning "cow", "So", refers to the "estuary", and finally "Kkak" means "end, limit, edge". This estuary is usually not easy to find as a tourist destination but it is worth deviating from the established routes to come and visit. We visited it in winter so there weren't too many people but that meant I was able to enjoy this place in all its glory. Nature here is pretty extreme, it's a combination of pine forest, sea, and volcanic sand that makes it stand out even more. It is small, easy to navigate and well suited for tourists. In high season you can rent a wooden boat to tour this estuary and venture into the river.
