Gideros Bay

Gideros Koyu, Kastamonu’s Cide district, approximately 11 kilometres from the district centre, is a protected coastal formation distinguished by its natural and historical features. The bay, known since the Genoese period as “Kytoros”, holds dual status as a first-degree natural and second-degree historical sit alanı. This coastal inlet, surrounded by boxwood, chestnut, oak and beech forests, contains archaeological remains, cave sites and Genoese ruins, making it an important destination for both nature and cultural tourism.

The history of Koyu extends back approximately 3,500 years to the Middle Chalcolithic Dönem, making it one of the few coastal settlements in Western Black Sea with an uninterrupted past. Archaeological surface surveys have uncovered Chalcolithic-period çanak çömlek fragments in the Çadır İni and Ballıcı İni caves; in the cave designated as Gideros Mağarası 1, Byzantine-era ceramics and remnants of religious structures have been identified. Additionally, wall remains, fortress structures and various architectural traces from the Roman-Byzantine periods have survived to the present day.

In ancient sources, the bay known as “Kytoros” was part of the Paftlagonya region and mentioned in Homer’s Iliad. The renowned geographer Strabo wrote that the first settlers of the region were the Amazons. The origin of the bay’s name most likely stems from this ancient settlement. Ancient commentators such as Eustathius used the phrase “Carry boxwood to Gideros” (Tereciye tere satmak), referring to the abundant boxwood trees in the area; this expression indicates that Gideros was a centre for high-quality boxwood products used in woodworking.

The Genoese period gave Gideros a special place in maritime history. During this time, the bay served as a shelter and resupply point for ships travelling between Sinop and Amasra. The region also became a haven for pirates alongside commercial vessels. The bay’s narrow entrance and naturally protected structure enhanced its function as both a refuge and a hiding place.

During the Byzantine period, the bay’s strategic importance increased, and it was used for military purposes thanks to the fortified Gideros Kalesi. Remains of Byzantine buildings and defensive architecture surround the fortress. In 1284, Yavlak Arslan, the bey of the Çobanoğulları Uç Beyliği, a vassal of the Seljuks, captured the fortress after a 16-day siege. This conquest strengthened Seljuk presence in the region.

During the Ottoman period, Gideros retained its importance for coastal security and supply. The structure believed to date from this period—a bathhouse submerged in the sea—is still visible today. In the Republican era, particularly during the National Struggle years, it was documented as having been used as an arms depot; its hidden yet strategically accessible location enabled such functions. Today, Gideros Koyu is preserved as an archaeological sit alanı while continuing to serve as one of the focal points of regional tourism due to its natural beauty and historical heritage.

During the Cide Archaeological Project conducted between 2009 and 2011, numerous archaeological finds were uncovered:

• Chalcolithic-era ceramic fragments in the Çadır İni and Ballıcı İni caves.
• Byzantine-era pottery and religious structures in Gideros Mağarası 1.
• Fortification remains in Gideros Kalesi.
• Gideros Hamamı (Ottoman period) and submerged structures.
• Early Bronze Age artifacts in Filyos Mağarası.

Gideros Koyu possesses a sheltered harbour character due to its narrow entrance to the sea and expanding interior. The bay’s seaward opening is approximately 130 metres wide, while its inner diameter extends to 514 metres. This özgün morphological yapı has served throughout history as both a natural refuge and a strategic shelter.

The area surrounding the bay is covered by a rich bitki örtüsü. Dominant and local tree species include boxwood, chestnut, oak, beech and pine. The changing shades of their year-round yeşil foliage create a striking visual atmosphere through reflections on the bay’s calm waters. Gideros has a humid, temperate microclimate with abundant rainfall, consistent with the general climate of the Black Sea region. This climatic structure ensures the year-round vitality of the dense forested areas around the bay.

The bay is also rich in wildlife. Wild ducks, among other bird species and coastal fauna, have become integral parts of this natural environment. The interwoven marine and forest ecosystems of this area hold significant value for ecotourism. Particularly during spring and sonbahar months, when migratory bird species use the bay as a stopover, the region becomes attractive to birdwatchers.

Gideros Koyu is located approximately 11 kilometres from the district centre and is accessible by both land and sea. Historically functioning as a natural harbour due to its narrow, protected structure, Gideros today retains this uniqueness as an appealing asset for nature tourism, historical tourism and maritime tourism.

In addition to natural coves suitable for swimming, Gideros Koyu features local fish restaurants and small accommodation facilities. These establishments enable tourists to enjoy day trips as well as extended stays. During summer months, especially on weekends, the area is visited not only by domestic tourists but also by foreign visitors from countries such as Almanya, Georgia and Ukrayna.

Gideros Koyu is protected as both a first-degree natural sit alanı and a second-degree archaeological sit alanı. These designations have largely prevented urban development, preserving Gideros’s natural state and enabling it to become a route aligned with the “quiet tourism” concept. Its green forest cover, clear sea, historical ruins, caves and beach offer visitors a multifaceted experience.
