Accessibility Note
What is the itinerary like?
What is so special about this experience?
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.
What is the best time for this tour?
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.
Who would love this tour?
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.
What to bring?
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.
How do we meet?
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.
Posted on Google Yazmin MehdiTrustindex verifies that the original source of the review is Google. We love Hike'n Sail tours so much, we have now used them twice. After a remarkable sailing trip on a gulet through the Dodecanese Islands in 2018, we knew we would ask Alper, Liliana and their team to help us plan a week on land in Turkey in May 2023. We prefer to use in-country tour operators because they know their culture, history and foods best. Hike'n Sail are top-notch in this arena. They've been doing this for years, they care about their clients, and they love Turkey and all it has to offer. The result is a series of unique experiences, delicious meals, stellar guides (truly, these folks are walking encyclopedias of history and culture) and skilled drivers. And the best thing is, all the people you meet are fun, personable, and funny, so you wake up every day, eager to spend more time with them. Our photos should give a few quick glimpses of why you should want to visit Turkey. It has been the crossroads of empires for thousands of years so the culture and history are deep and rich. It has a diversity of landscapes and seascapes that provide opportunities for hiking and sailing unmatched anywhere else: from mosques to fairy chimneys, from Hittite ruins to Roman and Greek ones, from dry arid landscapes to lush hillside villages. And the food! You won't come away hungry. We want to return to Turkey, and when we do, our first contact will be with Alper and Liliana. Highly recommend!Posted on Google Jeanne NewmanTrustindex verifies that the original source of the review is Google. Alper led an amazing trip to Turkey for my family and another family Our group had people with. Any different ages and interests. Amazingly, Alper made each of us feel like he planned the trip just for us. I have traveled many places and have had many guides, but none as excellent as Alper.Posted on Google Suad KUTLUGTrustindex verifies that the original source of the review is Google. Few years back we had a wonderful time with Hike and Sail in Istanbul. It was a full day in Istanbul sightseeing and food tasting. Alper, is a well educated professional guide that knows his city, its culture and history. He is proud of what he is doing and it shows. Did I tell you that he is also a foodie, an expert on Turkish flora and he has a great sense of humor. I highly recommend this company. We are looking forward to our post pandemic adventures with him. Bon Voyage :)Posted on Google liliana riosTrustindex verifies that the original source of the review is Google. Traveling with Hike'n Sail is the best way to experience Turkey. The sailing tours combined with hiking are my favorite, we got to spend the most wonderful time on a gullet going through amazing coves enjoying the beautiful turquoise waters. Alper is very knowledgeable and fun, without doubt the best trip ever!Posted on Google Pauline KuklisTrustindex verifies that the original source of the review is Google. My husband and I along with some friends did food and wine adventure 1 with Alper last year and loved it. We were hoping to do food and wine adventure 2 this year but will have to postpone until it is safe to travel. We had a great time with Alper. He is very passionate about travel and is incredibly knowledgeable about the history, culture, food and wine of Turkey. He also has incredible knowledge of wild flowers. We were a little early in the season when we went but he still managed to find things we didn't even see. If you are at all interested in visiting Turkey, and it is a great place to visit, then Alper is the best person possible to show it to you.Google rating score: 5.0 of 5, based on 7 reviews
