Autumn has arrived. Istanbul is even more beautiful in autumn. But what are the lesser-known hidden gems of the city, rather than the most obvious ones?

Here are 5 lesser-known hidden gems of Istanbul:

1. Atatürk Arboretum (Sarıyer): Located southeast of Belgrad Forest, this 345-hectare arboretum, or tree park, belongs to the Istanbul University Faculty of Forestry but is open to visitors. Entry is restricted to food and water only, and even cameras are not permitted except for those with special permits. The arboretum is a true paradise with its diverse plants, beautiful trees, and ponds adorned with water lilies. Especially in spring and autumn, the most beautiful colors of nature come together to create magnificent views. While you're here, take a long walk from Belgrad Forest to Kilyos beach.

2. Galata Mevlevi Lodge (Tunnel): Until recently little-known and referred to as the Museum of Ottoman Classical Literature, this museum was renovated in 2007 and reopened to the public in 2011 under the name and concept of the Galata Mevlevi Lodge. The complex, which houses the tomb of Sheikh Galib, one of the most important classical Ottoman poets of the 17th century and also the lodge's sheikh, is one of the most significant Ottoman structures in Beyoğlu, along with the "Galata Palace Enderun School," founded in 1481. Open every day of the week except Monday, the museum displays various musical instruments, Mevlevi artifacts from different periods, and other works of art. After a serene visit here, you can complete your day with a tour of Karaköy.

3. Molla Aşkı Hill (Balat): Originally named Mollaaşki, and although its "secret" status was diminished by the TV series Ezel, this park and its tea garden, now belonging to its regulars and neighborhood, are worth a visit for their magnificent view. From the Balat hills, it's possible to see Kayışdağ, Haydarpaşa, Selimiye barracks, Topkapı Palace on the right, and Galata on the left towards the horizon. A little further down, the Yavuz Selim Han Mosque, the Greek Red School, the Bulgarian Church, and the Jewish Synagogue stand side-by-side in the same silhouette, symbolizing the brotherhood of religions. This terrace is especially recommended for sunrise viewing. While you're there, don't forget to take a tour of Fener-Balat.

4. Otağtepe Park: Often overshadowed by Nakkaştepe in terms of visitor numbers, this beautiful hill offers unparalleled views of the Bosphorus at your feet, with the scent of pine trees filling your nostrils. While there are no food or drink options within the park itself, there are plenty of cafes and restaurants at the exit and in Nakkaştepe, which is easily accessible. This area is ideal for simply enjoying the view and taking a pleasant walk. The sunset is especially spectacular. While you're here, don't forget to take a nice stroll down to the Beykoz, Beylerbeyi, and Kuzguncuk area.

5. Caferağa Madrasa (Sultanahmet): Perhaps you've passed by it many times without noticing, but this madrasa, nestled in a small alley next to Hagia Sophia, awaits you, offering tranquility, numerous artists, and excellent apple tea. Composed of small rooms and, of course, another gift from Sinan the Great to Istanbul, the madrasa hosts courses and exhibitions on ebru (marbling), calligraphy, and many other handicrafts. After visiting here, exploring Sultanahmet again will surely be wonderful.
