Kastamonu is a historic city in Turkey's Western Black Sea region, sitting at roughly 800 metres above sea level in a valley carved by the Gökırmak and Kastamonu streams. Famous for its remarkably well-preserved Ottoman timber architecture, its imposing Byzantine-Ottoman castle, and a culinary tradition built around garlic, chickpea dishes, and cured meats, the city rewards visitors who venture beyond Turkey's coastal and Cappadocian tourist circuits. The surrounding province encompasses Ilgaz Mountain National Park — a winter ski destination — and the dramatic gorges of Küre Mountains National Park, offering some of the finest trekking in northern Anatolia.

Kastamonu Castle
This fortress sits on the hill directly above the old town, with foundations going back to Byzantine rule and major rebuilding under the Candaroğlu (Isfendiyarid) beyliks who made Kastamonu their capital in the 14th and 15th centuries. Most of what survives today is broken curtain wall and a couple of towers rather than an intact structure, but the site's value is the vantage point it gives over the timber-framed Ottoman houses packed into the valley below.

Küre Mountains National Park
Declared Turkey's first national park set aside specifically to protect old-growth forest, this range along the Black Sea coast side of Kastamonu province holds stands of mixed beech, fir and hornbeam that were never clear-cut, along with karst features like sinkholes and underground streams. It's a working destination for hikers and nature-watchers rather than a single sight - trails link village settlements, canyons and cave entrances across a large area.

3
Valla Canyon
Cut by a tributary of the Gökırmak near Taşköprü, this is one of the deeper canyons in the region, with limestone walls rising steeply above a walking trail that follows the streambed. Wooden and suspension footbridges carry the path back and forth across the water at several points, which is what makes the walk memorable rather than the canyon being exceptionally wide or long.

Mahmut Bey Mosque (Kasaba)
Standing in the small village of Kasaba outside Kastamonu, this 14th-century mosque is one of Anatolia's best-preserved wooden hypostyle mosques from the Candaroğlu period, built with carved timber columns and a painted wood ceiling rather than the domed stone construction typical of later Ottoman mosques. It's on Turkey's UNESCO tentative list, and the interior woodwork - especially the carved mihrab and the painted geometric and floral ceiling panels - is the reason it's worth the detour from the city.

6
Ilgaz Mountain National Park
This forested mountain range straddling the Kastamonu-Çankırı border is a national park built around dense pine and fir cover, and it doubles as one of the region's ski areas in winter thanks to a small resort on its slopes. Outside ski season it functions as a hiking and picnic destination, with the writer Reşat Nuri Güntekin's novel Çalıkuşu (The Wren) having used the mountain and its surrounding villages as a setting, which locals still reference.

Nasrullah Meydanı (Central Square)
This is the functional heart of Kastamonu, a riverside square on the Gökırmak named after the qadi Nasrullah, anchored by the Nasrullah Mosque and overlooked by the city's stone clock tower on the hillside above. It's less a single attraction than the place where the old town's café life, shops and foot traffic converge, and most walking routes into the historic quarter start from here.
-
9
Kastamonu Ethnography Museum
The museum occupies a restored Ottoman-era konak (mansion) and displays the everyday material culture of the region: embroidered textiles, traditional costumes, household items, and woodwork typical of Kastamonu's old town houses. Kastamonu itself is known for its dense concentration of Ottoman timber-frame houses, so the building is as much the exhibit as the objects inside it. A visit gives a sense of domestic life in a Black Sea-facing Anatolian town before the rooms were converted to display cases.

10
Kastamonu Leblebi Çarşısı
This is a small market street built around Kastamonu's specialty of leblebi, roasted and often flavored chickpeas that the town has produced and traded for generations. Shops here sell leblebi in multiple styles — plain roasted, sugared, salted, and spiced versions — alongside other local dried goods and nuts. It's a working commercial street rather than a curated food hall, so the experience is about browsing several small vendors and comparing what they roast.
