Düzce is a verdant province in northwestern Turkey's western Black Sea region, famed for its hazelnut orchards, rushing rivers, alpine forests, and the vast Efteni Lake wetland. Sandwiched between Istanbul and Ankara along the Trans-European Motorway (D-100), it offers whitewater rafting on the Melen River, mountain trekking toward Bolu's Yedigöller plateaus, and the culinary heritage of a region recognized as one of Turkey's great gastronomic belts.

Do's and don'ts
Quick guide to local norms.
Do
- Remove shoes before entering homes and some prayer spaces.
- Accept an offer of çay (tea)—refusing can be seen as impolite.
- Greet with 'Merhaba' (hello) and 'Teşekkür ederim' (thank you).
- Dress modestly when visiting mosques—cover shoulders and knees; women cover hair with a scarf.
- Bargain politely at markets—start at 60–70% of the asking price.
- Ask permission before photographing people, especially women.
Don't
- Do not eat, drink, or smoke in public during Ramadan daylight hours out of respect for fasting locals.
- Do not enter a mosque during active prayer unless invited.
- Do not publicly display affection—it can attract unwanted attention in conservative areas.
- Do not photograph military installations or police checkpoints.
- Do not discard food or bread on the ground—bread is sacred in Turkish culture.
- Do not point the sole of your shoe at someone while seated.
