Located in the southwestern Sea of Marmara, Avsa Island, historically known as Türkeli Island, is one of Turkey’s most popular island holiday destinations. Part of Balıkesir Province’s Marmara District, the island is renowned for its beautiful sandy beaches, crystal-clear waters, lively summer atmosphere, vineyards, and locally produced wines.
Easily accessible by ferry from İstanbul, Tekirdag, Erdek, and Bandırma, Avsa attracts thousands of visitors each summer seeking sunshine, swimming, water sports, and a relaxing island escape. While its vibrant nightlife and beach resorts make it popular with younger travellers, the island also offers peaceful coves, scenic landscapes, and historical sites for those looking to unwind.
History
Avsa Island has been inhabited since ancient times due to its strategic location in the Sea of Marmara. Throughout history, it came under the influence of the Greeks, Romans, Byzantines, and Ottomans.
The island’s fertile soil and favourable climate have long supported viticulture, and winemaking remains one of Avsa’s most important traditions. Visitors can still explore family-owned vineyards and wine cellars that preserve centuries-old techniques.
One of the island’s most important historical landmarks is the Monastery of the Virgin Mary (Meryem Ana Monastery), located in the Manastır district. Dating from the Byzantine period, the monastery stands as a reminder of the island’s rich religious and cultural heritage.

Avsa Island lies in the Sea of Marmara, west of Marmara Island and north of the Kapıdag Peninsula. Covering approximately 36 square kilometres, the island features rolling hills, vineyards, olive groves, rocky cliffs, hidden coves, and long sandy beaches.
The surrounding sea is renowned for its exceptional clarity and calm waters, making it ideal for swimming, boating, and water sports throughout the summer months.
