Kilyos: A Real Guide to Istanbul's Black Sea Beach Town

If you have already done the mosques, the palaces and the Bosphorus and you want a proper day at the sea, Kilyos is the answer most locals give. It sits at the northern tip of Istanbul’s European side, on the Black Sea, and on a hot weekend half of Sarıyer seems to be there. The water is colder and rougher than the Mediterranean, the sand is wide and golden, and the whole place has a relaxed, slightly scruffy charm that the postcard parts of the city do not.

This is not a manicured resort. It is a beach town with surf, kite schools, fish restaurants, a few beach clubs that throw parties, and a fortress you can only look at from the road. Here is how to get there, where to put your towel down, what it costs in 2026, and the one safety thing nobody warns you about until it is too late.

A short history of Kilyos

Kilyos is a village in the Sarıyer district of Istanbul, on the European side and right on the Black Sea. The name most likely comes from the Greek word “Kilya”, meaning sand, which fits a place defined by its long beach.

It started life as a fishing settlement and grew under Roman rule. After the empire split, the area belonged to the Eastern Roman (Byzantine) world, and a stone castle went up on the headland for defence. Control changed hands more than once: the Genoese held the fortress for a long stretch, and the area later passed to the Ottomans. Through the Ottoman centuries Kilyos kept a mixed population, with a Christian community living alongside everyone else. After the Turkish Republic was founded, the official name became Kumköy, which it still carries today, though locals and bus signs use both names interchangeably.

The 14th-century Genoese castle is still standing, and it was restored back in the era of Sultan Mahmud II. One honest warning: you cannot actually visit it. The fortress sits inside a military zone and is closed to the public, so the historic cistern, the old cannons and the giant plane tree inside the walls are off-limits. You can admire the silhouette from the approach road, and that is as close as you will get. If a fortress you can climb is what you are after, the Rumeli Fortress on the Bosphorus is a better fit and an easy add-on to the same side of the city.

What to do in Kilyos: the beaches

The beaches are the whole point. There is a free public stretch where you just walk onto the sand, drop your towel and swim, with kiosks and lifeguards in the controlled zones but no loungers or service. Most people, though, pay to get into one of the beach clubs for sunbeds, showers, food and a bit of order. Prices change every season, so treat the numbers below as a guide and check the club’s own page before you set off. At the time of writing, in June 2026, the day entry at the bigger clubs runs roughly 600 to 950 TL per person, with weekends at the top end.

Solar Beach

Solar Beach is the famous one, the big club with capacity for a couple of thousand people. It has restaurants, bars, shops and a real party reputation: through the summer it hosts live music, DJ sets and full-on concerts most weekends, and it is the address young Istanbul heads to when it wants a beach with a soundtrack. If you want sunbathing by day and a crowd by night, this is your spot. If you want quiet, look elsewhere.

Tırmata Beach and Restaurant

Tırmata is more of a family beach, clean and calm, with a large sun terrace and a seafood restaurant on site. It also runs a kite-surfing school, so it draws a sporty crowd alongside the families. Its 2026 season cards are already on sale, which tells you it is open and running this year. Come for the food and the easier vibe rather than the parties.

Uzunya Beach

Uzunya, over in the Demirciköy part of Kilyos, is the prettiest of the lot. It is a deep natural cove with a small harbour, golden sand and water clear enough that on a lucky day you can spot dolphins in the bay. The restaurant is known for fresh seafood. Because it is a bit further out and more secluded, it feels calmer than Solar even in high season, and it is the one I would point a first-timer toward for photos and a swim.

Burç Beach

Burç Beach is run by the Boğaziçi University alumni association, which gives it a young, student-ish energy. It is a long sandy stretch built for water sports, with kiteboarding and windsurfing, beach volleyball and open-air concerts. If you are into wind and waves rather than just lying down, this is the one.

If you would rather see how Kilyos stacks up against the rest of the city’s coast first, our Istanbul beach guide lays out every swimmable option side by side.

Where to eat in Kilyos

Beyond the beach-club kitchens, Kilyos has proper restaurants worth a stop. For Turkish food, the village pide and grill places do the job, and the fish restaurants near the shore lean on the day’s Black Sea catch. There is also an Italian option if you have had your fill of mezes. Honestly, my advice is simple: order whatever fish is fresh that morning, get a plate of mezes to start, and eat it with the sea in front of you.

How to get to Kilyos and where to stay

Kilyos sits roughly 40 to 50 kilometres from central Istanbul, so by car you are looking at about an hour from the historic core, more on a summer weekend when everyone has the same idea. Without a car it is genuinely easy: take the M2 metro to its northern end at Hacıosman, then catch the 151 IETT bus toward Kilyos / Demirciköy. The bus runs roughly every half hour and the ride from Hacıosman to the Kumköy stop takes around 40 minutes. Tap your Istanbulkart and go. For the full picture on lines, transfers and fares, our guide to getting around Istanbul on public transport covers it.

For staying over, Kilyos has the full range, from simple guesthouses to a few pricier boutique hotels, so it works as an overnight escape and not just a day trip. Booking ahead in July and August is wise because the village fills up.

Is it safe to swim at Kilyos?

This is the part most guides skip, and it matters. The Black Sea here is beautiful but it has a real reputation for rip currents, and Kilyos along with Şile on the Asian side is one of the spots where they catch people out every summer. Rip currents pull you away from shore, and the standard advice from lifeguards is blunt: do not try to swim straight back against the pull, because even strong swimmers lose that fight. Swim parallel to the beach until you are out of the current, then come in. A muddy, brownish patch of water reaching out from the shore is often a sign of a rip, so avoid it.

Two simple rules keep the day good: only swim in the flagged, lifeguarded zones of the beach clubs, and watch the flags. If a red flag is up, the sea is closed for a reason. With that respected, Kilyos is a brilliant, breezy day out.

Worth the trip?

For a beach day from Istanbul without leaving the city limits, yes, easily. Kilyos gives you real waves, wide sand, good fish and a choice between party energy at Solar and Burç or calm at Uzunya and Tırmata. Pair it with a green day at Belgrad Forest nearby, or fold it into a wider plan from our list of the most beautiful seaside places in Istanbul. Bring sunscreen, respect the current, and go.
