Kilyos Coast

6 min read

The other name of Kilyos is Kumkoy. The region is known for its botanically rich sand dunes. These sand dunes are very important because they are the second sand dune area with the richest plant diversity among the dune areas that can be preserved intact on the Black Sea shores. This unique coastal environment, located on Istanbul’s European shore, offers a refreshing escape from the bustling city just an hour away.

Historical Significance

The first building in Kilyos, the first to be hit, is the well-known castle built during the Genoese period.

The Genoese established trading colonies throughout the Black Sea region during the medieval period, and Kilyos served as one of their outposts guarding the entrance to the Bosphorus. The castle they built here commanded views of both the sea and the approaches to Constantinople, providing early warning of naval movements.

The castle, which was in the military field, was restored in the time of Sultan Mahmut. There is a cistern in the middle. When it rained, a system was installed to collect water to fill the cisterns. For a long time, all the cisterns up to Bahcekoy saw reconstruction and restoration in this period. The arched, sheltered guard sections are remarkably preserved with stones made of stone. A number of weapons made by Germans for the protection of the Bosphorus in World War II are also exhibited here. There are 8 different guns in the castle.

Ottoman Era Monuments

On the castle gate are Sultan Mahmut II brick, two battle balls on both sides. And in honor of the conquest of the castle, there is a monumental plane tree that erected at that time and reached daily. This ancient tree has witnessed centuries of history, its spreading branches now providing shade for visitors exploring the castle grounds.

With a height of 26 meters and a breadth of 5.4 meters, the plane has a date of 1460 indicating the date of planting. Three high-point water scales are considered part of the system that distributes water from the cistern. Other historical buildings in the area are the old buildings, boathouse, pier, bridges and fountains they used to control the entrance of the Bosphorus when the British invaded Istanbul. The salvage buildings are still being used by coastal protection.

Natural Heritage

The Kilyos sand dunes, which are under protection by the Society for the Protection of Natural Life, have a rare dune variety covering the vegetation cover and at least 15 dune plant taxa throughout the country. This ecological treasure represents one of the last intact coastal dune systems in the region, making it invaluable for scientific study and conservation.

The dune ecosystem includes plants specially adapted to the harsh conditions of shifting sands, salt spray, and intense sun. These pioneer species stabilize the sand, allowing other plants to colonize behind them. The result is a series of distinct vegetation zones from the beach to the inland forest, each with its characteristic plant community.

Beach Culture

Kilyos has developed as Istanbul’s premier beach destination, offering relief from summer heat to millions of city residents. Several beach clubs line the shore, providing facilities ranging from basic sun loungers to full-service resort experiences with pools, restaurants, and entertainment.

The most famous beach club, Solar Beach, has operated since the 1990s, establishing the model that others have followed. Modern clubs offer day packages including beach access, food and drink credits, and use of facilities. Weekend pricing typically exceeds weekday rates, reflecting the demand from Istanbulites escaping the city.

Public beach areas also exist for those seeking a more natural experience without club fees. These sections of coast offer the same beautiful Black Sea waters without the amenities or crowds of the commercial beaches.

Swimming Considerations

The Black Sea at Kilyos differs significantly from Mediterranean beaches in Turkey. The water temperature remains cooler, typically reaching its warmest in August and September. Currents can be strong, and the sea state changes quickly with weather conditions. Warning flags indicate when swimming is unsafe, and visitors should heed these warnings seriously.

Despite these cautions, millions swim safely at Kilyos each summer. The beach slopes gradually, allowing comfortable wading. The water clarity exceeds what might be expected near a major city, thanks to currents that continuously refresh the coastal waters.

Belgrad Forest Connection

Kilyos sits at the edge of Belgrad Forest, Istanbul’s largest forested area. This historic woodland, which served as the primary watershed for Constantinople for centuries, now provides recreational opportunities for city residents. Hiking and cycling trails wind through the forest, connecting with the coastal area.

The Ottoman-era aqueducts that carried water from the forest to the city remain partially visible, their massive arches standing in forest clearings. Historic reservoirs and fountains dot the woodland, monuments to the engineering achievements of past eras.

Combining a forest hike with a beach visit creates a full day excursion from Istanbul, experiencing both the cool shade of ancient trees and the refreshing waters of the Black Sea.

Getting to Kilyos

Kilyos lies approximately 35 kilometers from central Istanbul, accessible via the coastal road from Sariyer. Driving time varies considerably depending on traffic, ranging from 45 minutes to over two hours during peak periods. Weekend traffic in summer can be particularly challenging.

Public transportation options include buses from Haciosman metro station, though service frequency is limited. Ride-share services and taxis provide alternatives for those without cars. Some beach clubs arrange shuttle services for their guests.

Best Time to Visit

The beach season runs from June through September, with July and August bringing the warmest water temperatures and largest crowds. June offers pleasant weather with smaller crowds and lower prices at beach clubs. September provides warm water from summer heating, combined with fewer visitors as the school year begins.

Spring and autumn visits focus on hiking in Belgrad Forest and exploring the castle rather than swimming. The cooler weather makes outdoor activities more comfortable, and the forest displays seasonal color changes.

Food and Facilities

Kilyos village offers various restaurants and cafes beyond the beach clubs. Fresh fish features prominently on menus, caught daily by local fishermen. Traditional Turkish breakfast spreads are available at several venues, making for a leisurely start to a beach day.

The beach clubs typically offer full dining services, from snacks and drinks to complete meals. Quality and prices vary, with upscale clubs charging premium rates for their offerings. Bringing a picnic provides an economical alternative for those visiting public beach areas.

Practical Tips

Book beach club spots in advance for summer weekends, as popular venues fill quickly. Bring cash, as not all facilities accept cards reliably. Pack sun protection, as the Black Sea sun can be as intense as anywhere. Check weather forecasts before visiting, as conditions can change rapidly. Consider visiting on weekdays to avoid crowds and potentially secure better pricing at beach clubs.
