Heybeliada is the second largest of the Princes’ Islands in the Sea of Marmara. The horseshoe shaped bay on the South – Çam Limanı provides the most adequate sheltering of the Princes Islands. There are sea level rocks on the west at the entry. It is always best to keep some distance off the shore. There are sufficient depths on the eastern side. The depth in the middle is around 17 meters and it shelves ashore gradually. The beach side is surrounded by pine trees. Çamaltı bay provides sheltering from the northerly blowing winds. Southerlies push swell in. During the summer months these islands are popular destinations for day trips from Istanbul. As there is no traffic on the islands the only transport being horse and chart, they are incredibly peaceful compared with the city of Istanbul. The Naval Cadet School building dating from 1773 is one the most important buildings. The jetty of the school is private, berthing is not allowed. Provisional facilities are available in the town center. Restaurants and cafes that stays open all year round. Public market takes place on Wednesdays.
