Istanbul rewards a long stay, but its best days out reach well beyond the old town: an island of pine forests and horse-drawn-era streets an hour by boat, the first Ottoman capital in Bursa, and Sinan’s masterpiece in Edirne. This guide ranks the three honestly, with the do-it-yourself versus guided-tour call made for each. Sort your base first with our Where to Stay in Istanbul guide, fit the trips around our Istanbul in 3 Days itinerary, and keep our Istanbul Hidden Gems guide for the days you stay in town.

1. The Princes’ Islands — the easy escape
Ninety minutes by ferry from Kabataş, the Princes’ Islands are where Istanbul exhales: no cars on Büyükada, the largest island, just bicycles, electric shuttles, pine forest, and grand wooden mansions from the era when exiled princes — and later Trotsky — were sent here. Swim off the small beaches in summer, climb to the Monastery of St. George for the panorama back to the city, and eat fish by the harbor before the boat home.
DIY by public ferry is cheap and simple, but the tour version adds hotel pickup, lunch, and a second island (Heybeliada) without timetable stress. The pick is the Princes’ Islands tour with lunch (4.9 stars, Badge of Excellence): a full day with lunch on board and free time on Büyükada. Free cancellation up to 24 hours ahead.
Best for: a breather after two days of mosques and bazaars. DIY or tour? Both work — the ferry is half the fun if you’re comfortable navigating it.
2. Bursa — the first Ottoman capital
Bursa was the Ottomans’ first capital, and it still feels like the empire’s hometown: the Green Mosque and Green Tomb in their turquoise tiles, the vast Ulu Cami with its 20 domes, the silk merchants of the Koza Han courtyard, and İskender kebab in the city that invented it. Above it all rises Uludağ, reached by one of the world’s longest cable cars.
It’s a long day — about 12 hours — and the journey strings together a Bosphorus-side drive, a ferry across the gulf, and the mountain, which is exactly why the tour wins here. The pick is the guided Bursa and Uludağ day tour from Istanbul (4.8 stars): Green Mosque, silk market, lunch, and the cable car in one booking, with hotel pickup. Free cancellation up to 24 hours ahead.
Best for: history lovers who want the Ottoman story from its beginning. DIY or tour? Tour — the logistics genuinely earn it.
3. Edirne — Sinan’s masterpiece, as a splurge
Edirne, up near the Greek and Bulgarian borders, guards the Selimiye Mosque — the architect Sinan, in his eighties, called it his masterpiece, and its dome still floats over the Thracian plain. Add the old Ottoman hospital complex, the covered bazaars and the fried liver Edirne is famous for, and it’s the connoisseur’s day trip.
Be honest about the shape of this one: there are no big group tours — Edirne from Istanbul is a private day, priced per group (up to five), which makes it a splurge to split rather than a budget pick. The verified option is the Edirne Ottoman capital city tour, a private 9-hour day with hotel pickup built around the Selimiye Mosque. The DIY alternative exists — trains run from Halkalı station in around three hours — and suits independent travelers who want the mosque at their own pace.
Best for: architecture devotees and groups splitting the cost. DIY or tour? Private tour for ease; train for independence.
Worth knowing: Troy and Gallipoli are overnight trips
You’ll see Troy and Gallipoli sold as Istanbul day trips, and technically they run — but at roughly five hours each way they are 16-hour slogs that shortchange both sites. If either matters to you, sleep in Çanakkale and do them properly. Your Istanbul days are better spent on the three above.
How to choose
One trip: the Princes’ Islands, especially in warm weather. Two: add Bursa for the Ottoman depth. Three, with a group to split it: Edirne and the Selimiye. Book a few days ahead, start early for Bursa, and keep the islands for a weekday when the ferries belong to Istanbulites, not tour groups.
