Sacheonjin Port not only serves as a tourist attraction but is also a major hub for the fishing industry, with a wide variety of fish being caught.

Located about 5 minutes from Gyeongpodae and about 10 minutes by car from downtown Gangneung, Sacheonjin Beach is remarkably quieter compared to those areas. It retains the tranquil and gentle characteristics of the sea.

Beyond Sacheon Port, near the breakwater, lies the Gangneung Sacheon Yacht Stadium. Unlike other ports, it is enclosed in a way that separates it from the outside, where people enjoy yachting alongside white sandy shores. It is also a training ground for university yacht teams, and beginners can be seen freely practicing within the enclosed waters. Marine leisure camps are held here to promote yachting, and various programs are offered for students fatigued by studies and job preparation.

At the entrance of Sacheonjin Port, uniquely shaped rocks rising from the blue sea, along with seagulls, create a captivating scene. Walking around the breakwater, visitors will find an arched bridge over rocky shores, enhancing the scenery, as well as a sculpture of a diver riding a shark welcoming guests.

Fishing conditions are favorable both inside and outside the breakwater, especially for black porgy, along with a good variety of smaller fish. As a result, the breakwater is bustling with anglers on both weekdays and weekends. On the right side of the harbor stands a maritime safety watchtower, quietly ensuring the safety of those heading out to sea.

From the beach, the red lighthouse of Sacheonjin Port is clearly visible. Here, visitors can purchase fresh sashimi or rent a fishing boat for sea fishing experiences.
