When Istanbul's noise gets loud enough, locals have a pressure valve: the Princes' Islands (Adalar), a small car-free archipelago in the Sea of Marmara, under an hour and a half from the city by ferry. Pine forests, faded Ottoman-era mansions, swimming spots and not a single traffic light. Here's how to do a perfect island day in 2026.
Which island to pick
Buyukada.
The biggest and most famous, with grand wooden mansions, bougainvillea-draped lanes, and the hilltop Aya Yorgi church, whose terrace has the best view in the entire archipelago. Busiest on summer weekends, and worth it anyway.
Heybeliada.
The second-largest and many locals' actual favourite: quieter, greener, with pine forest walks and better swimming. Pick this one if crowds aren't your thing.
Burgazada and Kinaliada.
The small two. Burgazada is sleepy and charming with a handful of excellent waterfront fish restaurants; Kinaliada is the closest to the city and the most low-key. Good add-ons if you're island-hopping.
How to Get to Princes' Islands
Public ferries run from Eminonu and Kabatas on the European side and Kadikoy and Bostanci on the Asian side, all on your Istanbulkart, no advance booking needed. The trip to Buyukada takes roughly 90 minutes from Eminonu and less from the Asian side. Faster private sea buses (deniz otobusu) cut the time but cost more. Go early on summer weekends, morning ferries fill up fast, and check the last return sailing before you settle into dinner.
What to do once you're there
The islands are car-free, so it's walking, cycling or electric shuttle. Renting a bike is the classic move: a loop of Buyukada takes a couple of hours with swim stops. Hike or ride up to Aya Yorgi for the view, swim at one of the beach clubs or free rocky coves, and end with a long fish lunch by the water, calamari, mezes and cold drinks are the standard order.
Budget-wise, the ferry is nearly free with an Istanbulkart, bikes rent cheaply by the hour, and the main costs are lunch and a beach club sunbed if you want one. A full island day runs cheaper than a night out.
Skip Sunday if you can. Saturdays are busy but manageable; Sundays in July and August are a crush from the ferry queue onwards. A weekday island trip, if your schedule allows it, feels like having the whole archipelago to yourself.
