Heybeliada: The Pine-Scented Jewel of Istanbul

Welcome to Heybeliada: Istanbul's Emerald Haven

Rising from the sapphire expanse of the Sea of Marmara just twelve nautical miles southeast of the Golden Horn, Heybeliada (historically known in Greek as Chalki, named after the ancient copper mines worked during Byzantine antiquity) represents the most atmospheric, forested, and relaxed refuge in the Princes’ Islands archipelago. Spanning 2.34 square kilometers with four undulating hills, the island earns its modern Turkish moniker—literally "Island with a Saddlebag"—from the gentle saddle-shaped valley that dips gracefully between its northern and southern crests.

While neighboring Büyükada bustles with large commercial tour groups and day-tripper queues, Heybeliada retains an enchanting, introspective dignity. For centuries, this island has stood as a melting pot of Levantine merchants, Greek Orthodox theologians, Ottoman naval officers, Jewish financiers, and celebrated Turkish writers. Here, horse-chestnut and mimosa blossoms drape over 19th-century white-timber gingerbread villas, while salt breezes blend intoxicatingly with the resinous fragrance of Mediterranean maritime pines (Pinus brutia).

Whether your pilgrimage leads up the tranquil cobblestone ascent of Ümit Tepesi (Hill of Hope) to the cloistered gardens of the Halki Theological Seminary, along the coastal promenade past the red-brick clock tower of the Turkish Naval Academy, or into a waterfront meyhane for a glass of raki and grilled Marmara bluefish (lüfer), Heybeliada offers an authentic encounter with Istanbul’s maritime soul.

The Four Historical Hills of Chalki

Heybeliada's topography is formed by four distinct peaks, each anchored by its own religious, military, or ecological landmark:

• Ümit Tepesi (Hill of Hope / Papaz Dağı - 85 m): The northern summit crowned by the neoclassical campus and Byzantine chapel of the Halki Theological Seminary. Surrounded by landscaped cypress walks, citrus orchards, and old monastic vineyards.
• Değirmen Tepesi (Mill Hill - 136 m): The highest elevation on Heybeliada, named for the historic Ottoman grain windmills that formerly caught sea gusts from the Black Sea and Marmara. Dense maritime pines cover its western slopes.
• Taş Ocağı Tepesi (Quarry Hill - 84 m): Overlooks the eastern approaches and the channel separating Heybeliada from Büyükada, bearing geological traces of the Byzantine copper excavations that gave Chalki its classical name.
• Makarios Tepesi (Baltacıoğlu Hill - 98 m): The southwestern headland sheltering Çam Limanı, home to the historic 1924 Sanatorium grounds and shaded trails leading down to secluded Alman Koyu.

When to Visit: Four Seasons on the Island

Heybeliada undergoes dramatic seasonal transformations. In Spring (April to June), yellow mimosa and purple Judas-tree blossoms (erguvan) erupt across the slopes, while temperatures hover between 18°C and 23°C—ideal for hiking and cycling. Summer (July to August) brings warm sea breezes, vibrant beach club activity at Çam Limanı and Aqua Green, and bustling outdoor tavern terraces. Autumn (September to November) is the connoisseur’s season: the Marmara waters remain warm enough for swimming, the summer day-tripper crowds evaporate, and local fishermen haul in prized seasonal bonito (palamut) and bluefish (lüfer). Winter (December to March) is misty, contemplative, and peaceful, as woodsmoke drifts from historic timber chimneys and island cafes stoke their cast-iron stoves.

Curated Excursions & Ferry Tickets · 2026 Comparison

Navigating excursion options across the Princes’ Islands requires balancing price, flexibility, and convenience. Below, our maritime editorial desk compares the top four verified booking options for visiting Heybeliada, ranging from independent round-trip ferry passes to all-inclusive dual-island guided cruises.

The Halki Theological Seminary: Wisdom on the Hill of Hope

Perched atop Ümit Tepesi (Hill of Hope, 85 meters above sea level) amidst soaring umbrella pines, the Halki Theological Seminary (Aya Triada Manastırı) is one of the most intellectually revered monuments in Eastern Christendom. Established in 1844 by Ecumenical Patriarch Germanos IV upon the foundation of a Byzantine monastery founded by Saint Photius I in the 9th century, this grand neoclassical complex served as the premier theological academy of the Orthodox Church for over 125 years.

The seminary educated countless patriarchs, bishops, and theologians—including the current Ecumenical Patriarch Bartholomew I—before higher educational licensing shifts resulted in the suspension of active teaching in 1971. Today, the complex is maintained with immaculate care. Visitors walking the serene forested path are greeted by resident peacocks strutting across classical courtyard terraces, shaded Byzantine colonnades, and a world-class historical library housing over 40,000 rare manuscripts, incunabula, and early printed volumes.

The Historic Naval Cadet Academy (Deniz Lisesi)

Stepping off the ferry onto Heybeliada’s stone quay, the immediate visual landmark dominating the northern shoreline is the magnificent compound of the Turkish Naval High School (Heybeliada Deniz Lisesi). Founded in 1773 during the reign of Sultan Mustafa III as the Mühendishane-i Bahr-i Hümayun (Imperial Naval Engineering School) by Grand Admiral Cezayirli Gazi Hasan Paşa, it is the oldest specialized military technical academy in Türkiye.

The academy moved permanently to Heybeliada in 1851, constructing grand stone neoclassical quarters, an imposing seaside parade ground, and a landmark Italianate clock tower that chimes over the harbor. The institution educated generations of Ottoman and Turkish Republic maritime commanders, explorers, and naval engineers, including national poet Nazım Hikmet, who studied here as a cadet in 1913. While the operational naval academy grounds remain an active military heritage precinct, its stately waterfront facades and historic training cutters moored in the basin form an indelible element of Heybeliada's identity.

Çam Limanı: Pine Harbor & The Historic Sanatorium

On the southern sweep of the island lies Çam Limanı (Pine Harbor), a stunning natural horseshoe-shaped bay encircled by dense amphitheater-like slopes of virgin pine trees. This protected inlet is celebrated throughout the Sea of Marmara for its mirror-flat emerald waters, sheltered anchorage for sailing yachts, and microclimate rich in oxygen and maritime aerosol.

Overlooking the bay stands the historic Heybeliada Sanatorium (Heybeliada Sanatoryumu). Founded in 1924 by personal decree of Mustafa Kemal Atatürk as the young Turkish Republic’s first specialized tuberculosis sanatorium, the institution was positioned specifically on this pine ridge because Swiss and French medical advisors identified Heybeliada's southern air as having extraordinary pulmonary therapeutic value. Generations of patients—including celebrated poet Rüştü Onur—recuperated along its sun-drenched verandas. Today, Çam Limanı remains Heybeliada’s favorite destination for summer sailing excursions, tranquil coastal walking, and quiet swimming.
