A long stretch of coast between the Marmara and the northern Aegean, anchored by Ayvalık and its olive oil culture, with islands, bird wetlands, thermal springs and Mount Ida in the same province.
Ayvalık is the anchor. The town has been an olive oil centre for centuries and the architecture shows it: stone houses, church towers and factory chimneys now repurposed as boutique hotels. Cunda Island, connected by causeway, holds the restored Taksiyarhis Church and some of the best seafood meyhanes in the country, with 22 small islands of the Ayvalık National Park within reach by boat in an afternoon. South of the town the Edremit Gulf coast and Mount Ida (Kaz Dağları) rise straight from the sea.
Further north, Manyas Kuşcenneti holds 266 bird species, including breeding pelicans and spoonbills, on the main migration corridor between three continents. The Kapıdağ Peninsula projects into the Marmara from Erdek with pine forest and calm bays and almost no tourist infrastructure. Inland, the Gönen thermal springs have been used since antiquity. Pergamon and Assos, both in neighbouring provinces, are an easy day each from an Ayvalık base.
