Istanbul Princes' Islands — Büyükada Car-Free Day

A Car-Free Marmara Escape, Two Hours from the Bazaar

The Princes' Islands (Adalar) are a chain of nine islands scattered across the Sea of Marmara, roughly 5 km off Istanbul's Asian shore. Once the place where Byzantine emperors exiled disgraced relatives and aristocrats to island monasteries, today they are the city's beloved car-free retreat. Büyükada, whose name simply means "Big Island," is the largest at about 5 square kilometres, with a year-round population near 8,000 that swells through summer. No private cars run here: you move by foot, bicycle, or electric cart, and the air smells of pine and sea instead of exhaust.

Getting There: The Ferry Crossing Is Half the Pleasure

Public ferries sail to Adalar from Kabataş, Eminönü, Beşiktaş, Kadıköy and Bostancı, running at least eight times daily year-round; the crossing typically takes about 1 to 1.5 hours depending on departure point and how many islands the boat calls at first. On a private tour we collect you door-to-door, handle the ferry tickets, and time the boat so you face open-deck Marmara views rather than queues. Bostancı, on the Asian side, is the closest mainland pier and the shortest hop to Büyükada.

What You'll See and Do on Büyükada

You step off at Büyükada's elegant Art Nouveau ferry terminal into Lunapark Square, the island's lively hub of cafés and bakeries. From here the day unfolds at a gentle pace: a loop through the back lanes of grand Ottoman-era wooden mansions, a pause at the iconic Splendid Palace Hotel with its white timber façade and twin domes, and a winding climb toward Aya Yorgi. In between there is time for a seaside fish lunch, a swim if the season allows, and easy people-watching among bicycles and quiet electric carts.

• Lunapark (Birlik) Square and the Art Nouveau ferry terminal, the island's beating heart
• Streets of carved wooden köşk mansions, many over a century old, and the 1908 Splendid Palace Hotel
• The climb to the Greek Orthodox Church of St George (Aya Yorgi) atop the island's highest hill
• Pine woods, hidden coves and swimming spots around the island's perimeter
• A relaxed waterfront lunch of grilled fish and meze
• Optional electric-cart sightseeing loop past the old mansions and shaded forest roads

Aya Yorgi: The Hilltop Monastery of Wishes

The Greek Orthodox monastery of Hagios Georgios Koudounas (St George of the Bells) crowns Yücetepe, Büyükada's highest point at around 200–203 metres — the loftiest spot in the whole archipelago. A monastery probably stood here as early as the 10th century; after a monk named Isaiah rebuilt it following the 1751–52 rediscovery of a sacred icon, it was officially recognised in 1760, and the present church dates to 1897. The walk up from Lunapark Square is about 750 metres of steady cobbled climb, taking most people 20–30 minutes. Pilgrims tie a colourful thread to a bush at the bottom and unspool it in silence all the way up, carrying a single wish.

Heybeliada: The Quieter Second Island

Many full days pair Büyükada with Heybeliada (Greek: Halki), the second-largest island and noticeably calmer. Its forested hills shelter two landmarks of history: the Naval School, founded in 1773 as the Ottoman school of naval engineering, and the Halki Theological Seminary, established on 1 October 1844. Once the foremost Greek Orthodox seminary in the world — it trained nearly a thousand graduates, including twelve patriarchs such as Bartholomew I — it has stood closed since 1971, though there is renewed hope it may reopen. Heybeliada's pine woods, swimming bays and waterfront promenade make it a serene counterpoint to busy Büyükada.

Best Season and Timing

Late spring (May–June) and early autumn (September–October) are ideal: warm enough to swim, mild enough to climb Aya Yorgi comfortably, and free of the peak-July crush when day-trippers from the city pack every ferry. Midsummer is hot and busy, while winter is atmospheric and almost empty but cooler and breezier, with reduced café and boat activity. Start early — the first ferries leave before 06:00 and morning light is best for the climb and photos — and aim to catch a mid-to-late-afternoon boat back before the evening return rush builds.

• Spring and early autumn: best balance of weather, swimming and smaller crowds
• Midsummer: warmest water but the most crowded ferries and squares
• 23 April (St George's Day): unforgettable pilgrimage, but extreme crowds
• Winter: peaceful and moody, fewer services, pack a windproof layer
• Always allow buffer time for the return ferry on weekends and holidays

What to Wear and Bring

Comfortable closed walking shoes are essential — the cobblestones and the Aya Yorgi climb are unforgiving in sandals. Bring a hat, sunglasses and sunscreen, as much of the hilltop path is exposed. Pack swimwear and a towel from May onward, plus a light layer for the breezy ferry deck even in summer. If you plan to step inside the monastery church, dress modestly with shoulders and knees covered, as you would for any place of worship. A refillable water bottle is handy on the climb, though we keep chilled water in the vehicle.

Who This Day Suits

This is a wonderfully flexible day. Couples come for the romance of timber mansions and sunset ferries; families love the bicycles, beaches and the novelty of a town with no cars; history-minded travellers savour the Byzantine, Ottoman and Greek Orthodox layers and Trotsky's 1929–1933 exile years here. The one consideration is the Aya Yorgi climb, which is steep enough to challenge anyone with limited mobility or young children — but it is entirely optional. An electric cart can show you the mansions and woods at sea level while keeping the day easy and inclusive for all ages.
