Tucked away at the base of Kaleiçi's ancient walls, Mermerli Beach is a charming little secret for a refreshing dip right in the heart of the Old Town. You'll find this cozy cove by heading through the Mermerli Restaurant and down a flight of stairs, which opens up to a stunning view of the clear, calm Mediterranean. It's a paid beach, which includes your sunbed and umbrella, perfect for spending a few hours soaking up the sun with the historic harbor as your backdrop. The beach is more pebbles than sand, so consider bringing water shoes for comfort.
