Sivriada is a small, rocky islet in the Sea of Marmara that is administratively part of Istanbul, Turkey. The island is uninhabited and has no public facilities.

As a lesser-known islet there are no developed attractions on Sivriada; it is principally of interest from the water for short boat trips and for views of seabirds and the Istanbul coastline. Landing is uncommon and visitors should expect a rugged shoreline and no visitor infrastructure.

The islet appears in maritime and local records from historical periods but has long been without a permanent population. Its small size and exposed location have limited any sustained development or settlement.

Sivriada sits in the Sea of Marmara near the Princes’ Islands group and lies off the Asian shore of greater Istanbul, within the metropolitan area of the city.

Tips for Visiting Sivriada #

  • Best visited in calm weather and early morning when sea conditions are usually gentler and private boat tours are quieter, making landing and photography easier.
  • Sivriada is an uninhabited islet reached by private boat or by joining a Marmara/Islands boat tour rather than regular commuter ferries - arrange transport in advance from Istanbul piers or a licensed charter operator.
  • Many visitors only see the islet from passing boats; if you plan to land, tell your boat operator ahead of time and allow time to explore the shoreline and ruins before the return trip when waves and traffic can pick up.
