An hour away from Istanbul’s clamor, Heybeliada breathes at a different rhythm. The city’s noise fades behind the cry of seagulls and the hum of boat engines, replaced by pine-scented air, tranquil coves, and a slow pace. The greenest of Istanbul’s Princes’ Islands is more forest than town, more calm than commotion.

The island’s name hints at its shape: a saddlebag, or “heybe” in Turkish. It stretches across four gentle hills – Değirmen Tepesi (137 m), Ümit Tepesi (85 m), Köy Tepesi (128 m), and Baltacıoğlu Tepesi (98 m) – where pines rise and quiet footpaths curve through the greenery.

Heybeliada: From Past To Present

Once known as Halki, the island took its name from the copper that was mined here centuries ago. Unlike its sister islands, which often served as exile outposts, Halki followed a different path. The island became a haven for monks and patriarchs, whose monasteries and retreats still overlook the shore.

By the mid-19th century, Heybeliada had become a seasonal refuge for Istanbul’s mosaic of cultures. Greek fishermen, Armenian merchants, Jewish intellectuals, and Levantine traders, all drawn by the scent of pine and calm sea.

With the Tanzimat reforms, Ottoman elites arrived and shaped the island by building wooden mansions, schools, and hospitals. Yet change arrived gently. Electricity didn’t reach Heybeliada until 1935. Even then, evenings unfolded at their own pace, lit by oil lamps and softened voices.

Even today, Heybeliada keeps its unhurried rhythm, welcoming Istanbulites and travelers seeking a peaceful day trip or weekend escape from the city’s chaos. Less developed than its neighbor, Büyükada, it has fewer hotels, restaurants, and distractions. A waterfront of cafés and a narrow shopping street gives way to quiet neighborhoods, deep forest, and some of the archipelago’s best beaches and picnic spots. High above, monasteries and stone chapels await discovery. Nothing demands attention, yet everything draws it.

What To Do And See In Heybeliada 

On Heybeliada, time and geography will gently undo your plans, and that’s part of the charm. To truly discover the island, consider staying overnight. Its beaches, forest paths, and historic chapels offer plenty to see over a day or two. It’s also worth experiencing the island in the late hours: when the last ferry departs and the air cools, a different kind of beauty emerges – silent and almost indescribable.

OUTDOOR ACTIVITIES IN HEYBELIADA

Heybeliada offers a wide range of outdoor experiences, shaped by its natural landscape. Forested hills and coastal paths invite walking, hiking, or cycling, while the island’s coves and beaches provide space to swim or relax by the water. With no private vehicles allowed, the island stays quiet and clean. This makes it appealing for nature lovers, families, and anyone looking to spend a day outdoors.

  • Değirmenburnu Nature Park

Değirmenburnu (literally “Mill Point”) is located on Heybeliada’s western tip. It is known for its picnic spots, scenic walking trails, and clear waters ideal for swimming and snorkeling. Although this well-kept nature park isn’t exactly a secret, it’s far enough from the crowds to feel like a peaceful retreat.

You can easily reach Değirmenburnu by bike or on foot from the island center. Electric minibuses (lines HA‑1, HA‑2, and HA‑3) also run from the pier to the area. Entry to the park is free, but a small fee applies for using the beach and picnic facilities. Notably, Değirmenburnu is the only place on the island where barbecuing is officially allowed. You can rent a grill on-site and enjoy a proper cookout beneath the trees.

Besides the main park, hidden spots for swimming await, along with several private beach clubs. Some clubs offer aqua parks, perfect for families with children. Others cater to those seeking a lively atmosphere or quiet places to relax.

  • Ümit Hill

Close to Değirmenburnu, Ümit Tepesi (Hill of Hope) rises quietly. It is crowned by the Halki Theological School, the island’s most significant spiritual and architectural landmark. Though the seminary itself isn’t open to visitors, the grounds offer a peaceful climb with sweeping views of the Sea of Marmara and the tranquil surroundings.

Forested, mostly unpaved paths link Ümit Tepesi with Değirmenburnu, winding through pine trees and natural clearings. These trails are ideal for casual walkers who want to blend nature with history.

  • Çamlimanı Nature Park

Çamlimanı (Pine Harbour) Nature Park is a beautifully peaceful spot, with shaded picnic areas beneath trees and calm waters. The surrounding forest and sea provide a serene backdrop for swimming, boating, or simply unwinding.

The park is easily accessible from the main harbor, about a 40-minute scenic walk depending on your pace. Alternatively, you can take the electric minibus, which drops you nearby, just a short walk from the park entrance. A modest entry fee applies to access the park.

The area also has private beach clubs: some are lively and vibrant, while others offer quiet, peaceful spaces. Nearby, free swimming spots provide additional options.

  • Değirmen Hill

As the highest point on Heybeliada, Değirmen Tepesi offers sweeping views of the Sea of Marmara and the surrounding islands. At its summit stand the stone remains of an old windmill called Kutrulomilo, once connected to the nearby Byzantine-era Panayia Kamariotissa Monastery.

The walk to the top winds through pine forests along an unpaved, scenic trail. The path includes both gentle stretches and steeper sections, making it suitable for casual walkers as well as more adventurous hikers.

The eastern ridge of Değirmen Tepesi extends to Köy Tepesi (Village Hill), which rises to 128 meters. While there are no facilities at the summit, the area is ideal for nature walks and photography. The hill is accessible via hiking trails from various points on the island, including Değirmen Tepesi. The paths are mostly unpaved and can be steep in places, so appropriate footwear is recommended.

  • German Bay

Alman Koyu, or German Bay, is one of the cleanest and most secluded swimming spots on Heybeliada. Its calm waters are ideal for swimming and snorkeling, though the rocky shoreline can make entering the water somewhat difficult without proper footwear.

Access to the cove is limited, with a steep and uneven path leading down the hillside. A small facility nearby may not meet all your needs, so it’s best to bring your own food and supplies. But the efforts are well worth it: it’s the perfect spot for a picnic, surrounded by the peaceful charm of Heybeliada.

INDOOR ACTIVITIES IN HEYBELIADA

Heybeliada’s quieter appeal continues indoors, where cultural and spiritual spaces reflect the island’s layered past. Visitors can explore its historic and cultural heritage, from places of worship to sites tied to Ottoman and Republican intellectual life.

  • Bet Yaakov Synagogue

The Bet Yaakov Synagogue was built in the early 1950s to serve Heybeliada’s growing Jewish community. Today, it is overseen by the Neve Shalom Foundation. Modest in appearance, the building usually remains closed and isn’t open to visitors without prior arrangement.

  • Hagios Nikolaos Church

The Greek Orthodox Church of St. Nicholas (Hagios Nikolaos) was built in 1857 by architect Stefanis Gaitanakis. It rises prominently over Heybeliada’s main square, nestled between İşgüzar and İmralı Streets.

The deep red church stands out with its separate bell tower, set apart from the main building. Behind the altar lies the tomb of Patriarch Samuel Hançeri. In front of the narthex, a small standalone structure shelters the sacred fountain of St. Paraskevi (Hagia Paraskevi), adding another layer of spiritual significance to this historic site.

  • Hüseyin Rahmi Gürpınar Museum

The Hüseyin Rahmi Gürpınar Museum is the writer’s preserved home in Heybeliada, opened to the public in 2017. The three-story house displays his personal belongings, including his hand-knitted works and the desk where he wrote. It also features authentic 1920s décor, offering a glimpse into daily life of that era.

Hüseyin Rahmi Gürpınar (1864–1944) is a key figure in Turkish literature. He is best known for his realistic stories set in Istanbul and Heybeliada, where he lived from 1912 until his death.

  • İsmet İnönü House

The İsmet İnönü Mansion on Heybeliada offers a glimpse into the private life of one of Turkey’s most pivotal figures. İsmet Pasha, Atatürk’s close companion and Turkey’s second president, often retreated here to rest. He later spent his summers in this elegant 1920 neo-classical house, originally built by tobacco merchant Mavromatis.

Preserved as a house museum, it still holds original furnishings, many gifted by Atatürk himself. It invites visitors to step into the intimate world of a statesman who helped shape modern Turkey’s birth and early years.

  • Hagios Georgios Monastery

The Hagios Georgios Monastery, known in Turkish as Terk-i Dünya Manastırı (“Renunciation of the World”), sits at the western tip of the crescent-shaped bay called Çam Limanı. It was founded in the 1860s by a young monk seeking solitude and a life removed from worldly concerns. The monastery took its current form in 1954.

Famous for its distinctive red-pink façade, the monastery stands out against the surrounding pine trees and the deep blue sea. It is one of the island’s most picturesque landmarks.

  • Theological School of Halki (Halki Seminary)

High atop one of Heybeliada’s pine-covered hills stands a silent landmark of faith and intellect. Founded in 1844 on the grounds of the ancient Monastery of the Holy Trinity, the Halki Seminary was once the beating heart of Orthodox theological education. It shaped generations of spiritual leaders before its closure in 1971.

The surrounding silence belies its past as a crossroads of belief, scholarship, and diplomacy. Its gates closed, but its legacy still fiercely alive.

  • Heybeliada Sanatorium

Tucked among pine trees on the island’s southern slope, Heybeliada Sanatorium was Turkey’s first pandemic hospital, founded in 1924 on the orders of Mustafa Kemal Atatürk.

For decades, it served as a hub of treatment and research, offering care to countless patients, including prominent figures such as İsmet İnönü, Ece Ayhan, and Rıfat Ilgaz. Though closed to visitors today, the building remains a haunting silhouette above the sea.

  • Heybeliada Naval High School

Rising prominently at the island’s edge, the Heybeliada Naval High School has stood as a symbol of Turkey’s maritime legacy for nearly 250 years. Originally founded in 1773 in Istanbul as the Imperial Naval Engineering School, it relocated to Heybeliada in the 1850s. There, generations of naval officers trained amid the island’s serene pine forests.

Although the school closed in 2016 during a period of political unrest, its grand historic campus still offers striking views. It also serves as a reminder of the island’s role in shaping the nation’s naval tradition.
