This experience introduces travelers to a lesser-known natural landscape on the edge of Istanbul while highlighting the delicate relationship between biodiversity and conservation. The walk focuses on the Aydos snowdrop (Galanthus plicatus subsp. byzantinus), a rare and locally significant plant that blooms in early spring.

Discovering Istanbul’s hidden nature

Only a short distance from the city, Aydos Forest reveals a very different side of Istanbul — quiet woodland trails, seasonal flora, and a landscape rarely visited by any tourists.

This tour is exclusively available in January & February (depending on the snow fall), as this is the only time the endemic Istanbul snowdrop (Galanthus plicatus subsp. byzantinus), and Crocus istanbulensis are in bloom. The cold winter air provides the necessary conditions for these rare flowers to emerge, making this a truly seasonal and fleeting natural event.

This walk is ideal for nature enthusiasts, botanists, solo travelers, and couples who prefer quiet, contemplative outdoor experiences. If you are passionate about biodiversity, conservation, or macro-photography, this specialized journey into Istanbul’s “green lungs” will be a highlight of your winter.

  • Sturdy hiking boots: Waterproof boots with good grip for muddy forest trails.

  • Walking poles: Helpful on steep sections and uneven terrain.

  • Warm layered clothing: Thermal layer, fleece, and a windproof jacket for cooler summit conditions.

  • Rain jacket: Winter weather can change quickly in the forest.

  • Water and a light snack: To stay hydrated and energized during the hike.

  • Camera or macro lens: Great for photographing the delicate snowdrops and small forest plants.

We will meet at 09:00 AM in front of Karaköy Ferry Terminal, and transfer 1 hour by minivan. Please find your guide carrying the Hike’n Sail sign.
