Heybeliada, the second-largest of Istanbul’s Princes’ Islands, is known for its lush pine forests, historic sites, and relaxed atmosphere. Less crowded than Büyükada, it offers a quieter escape with charming streets, traditional wooden houses, and scenic coastal views. One of its most significant landmarks is the Halki Seminary, a former Greek Orthodox Seminary located on Ümit Hill. The island also has several beautiful beaches, walking trails, and waterfront cafés where visitors can enjoy fresh seafood. With no motor vehicles allowed, people explore Heybeliada by bicycle, electric minibuses, or on foot, making it an ideal destination for a peaceful day trip away from Istanbul’s busy streets.
