Yeosu is a coastal city in South Jeolla Province, spread across a peninsula and numerous islands along Korea's southern coast. Its geography is defined by sheltered bays, rocky shorelines, wooded hills, and the waters of the Korea Strait. The city is known for its maritime setting, seafood, island communities, and coastal viewpoints. Bridges and ferries connect different parts of the area, while Yeosu's waterfront combines working harbors with promenades and cultural attractions. Its position among islands gives the city a distinctly nautical character and provides access to a wide range of coastal landscapes.

Yeosu has a strong connection with Korea's naval history, particularly through Admiral Yi Sun-sin and the naval forces associated with the Imjin War. Jinnamgwan Hall is an important historic landmark linked to the city's former naval command and is recognized as a national cultural heritage site. Nearby sites also commemorate Admiral Yi, whose activities are closely associated with the region. Traditional fishing and maritime communities remain part of local identity, while festivals and cultural events often draw on Yeosu's relationship with the sea. The city's historic sites provide context for understanding its strategic importance along Korea's southern coast.

Odongdo Island is one of Yeosu's best-known attractions, connected to the mainland by a breakwater and walkway. The island has wooded paths, coastal views, and camellia trees that are closely associated with its landscape. Dolsan Park overlooks the harbor and surrounding islands, while the Dolsan Bridge provides a prominent view across the water. Yeosu Maritime Cable Car crosses the harbor between Dolsan and the mainland, offering views of the coastline and nearby islands. Further offshore, the Hallyeohaesang National Park area protects a complex landscape of islands, sea channels, forests, and rocky coastlines.

Seafood is central to Yeosu's food culture, reflecting its location beside productive coastal waters. Local restaurants commonly serve dishes featuring fresh fish, shellfish, octopus, and other marine products, while gat kimchi made with mustard greens is a specialty strongly associated with the region. Seodaehoe, a raw fish dish prepared with a spicy seasoning, is another local favorite. Yeosu's fish markets provide a direct connection between the city's fishing economy and its cuisine. The combination of island geography, naval heritage, seafood traditions, and coastal scenery makes Yeosu an important destination in southern South Korea.
