Beaches & Swimming on the Princes' Islands
Yes, you can swim on the Princes' Islands — and the water is some of the clearest near Istanbul. Here are the best beaches and beach clubs, island by island.
Ask an Istanbulite where to swim near the city and many will point to the Princes’ Islands. Away from the busy urban shoreline, the water here turns a clear Aegean blue, and every visitable island has somewhere to take a dip — from organised beach clubs to rocky platforms you reach on foot.
When is the swimming season?
The sea is comfortably warm for swimming from roughly June to September, peaking in July and August. May and early October can be pleasant on a sunny day, but the water is cooler and many beach clubs run a shorter season.
Beach clubs vs. free swimming spots
Beach clubs charge a day fee and give you loungers, umbrellas, showers, changing rooms and a café — ideal for a relaxed day. Public spots and rocky coves are free and more natural, but bring your own water, shade and towel.
