The Euboean Gulf is a large body of water located in central Greece, separating the island of Euboea from the mainland. It is part of the Aegean Sea and is known for its picturesque landscapes and rich marine life. The gulf is approximately 40 kilometers long and varies in width, making it an important area for both fishing and tourism. Several towns and cities, such as Chalkida and Kymi, line the shores of the Euboean Gulf. The gulf is also significant for maritime activities, including shipping and sailing, due to its relatively calm waters. Its historical importance dates back to ancient times, contributing to the region's cultural heritage.
