Kekova Sunken City: The Boat-Only Guide to Turkey's Underwater Ruins

Why “sunken city” doesn’t mean what most visitors picture

The name conjures images of snorkellers gliding over intact Roman streets, and that expectation is exactly what causes disappointment for some visitors to Kekova. The reality is quieter and more restricted: a series of earthquakes, most significantly in the 2nd century CE, dropped sections of the ancient settlement of Dolchiste into the sea along the coastline near modern Kaş and Kalkan. What remains are partially submerged walls, staircases and building foundations visible just beneath the surface in a handful of coves, along with ruins that stayed on dry land nearby.

Crucially, this whole stretch is a protected archaeological and natural site. Swimming and diving directly over the submerged ruins are prohibited by law. Boats are permitted to pass slowly over the clearest sections so passengers can look down through the water, and anchoring is restricted to designated points away from the ruins themselves. This isn’t a case of an unenforced rule that locals quietly ignore — patrol boats operate in the area, and it’s treated seriously as a way of protecting a fragile underwater site from damage. Knowing this before booking changes what you should expect from the day, and it’s the single most useful piece of context on this page.

What a Kekova boat trip actually includes

A standard Kekova day trip is built around a slow boat circuit rather than a single stop. The core elements, in roughly the order most operators run them:

• The pass over the sunken ruins — the boat slows and often cuts its engine near the clearest submerged sections, letting passengers lean over the rail or use the boat’s glass-bottom panel where fitted. This is the “sunken city” portion, and it typically lasts a matter of minutes at each spot rather than a full swim stop.
• Kaleköy (Simena) — a small village reachable only by boat or on foot, built beneath and around a hilltop Crusader-era castle. Most trips anchor offshore and ferry passengers in by dinghy or let the main boat dock briefly, with free time to climb up to the castle for a view over the bay and scattered sarcophagi below.
• Üçağız — the harbour village nearest to the ruins, sometimes a stop in its own right, sometimes just the point boats depart from on shorter itineraries.
• Swim stops — one or two breaks in open bays that are away from the protected ruins, where swimming is entirely normal and expected. This is where the “swimming at Kekova” part of the day actually happens, just not over the archaeological site itself.
• Lunch — usually included on full-day tours, either cooked on board or at a small harbourside stop.

Because so much of the value is in the setting — quiet water, pine-backed cliffs, the castle silhouette — visitors who arrive treating this as a scenic boat day with a historical layer tend to come away satisfied. Those expecting to snorkel through Roman streets are the ones who feel let down, and that gap in expectations is worth closing before you book rather than after.

Kaş or Kalkan: where to start the trip

Both towns sit within easy reach of the Kekova area and run comparable boat trips, so the choice mostly comes down to where you’re already staying or which town appeals more as a base.

	Kaş	Kalkan
Character	Slightly larger, laid-back harbour town, popular with divers	Smaller, more upscale resort feel, boutique hotels
Boat trip style	Wide choice of operators, from large group boats to smaller kayak/canoe tours	Similar range, often marketed toward couples and slightly quieter groups
Good pairing	Kaputaş Beach, further Lycian coast stops	Saklıkent Canyon and Patara combinations
Typical trip length	Full day (roughly 6–8 hours)	Full day (roughly 6–8 hours)

Neither town has a meaningful edge in trip quality — it’s more a question of atmosphere. Kaş leans toward independent travellers and the diving crowd; Kalkan leans slightly more polished and couple-oriented. Either way, a boat trip from Kaş or a Kekova boat trip from Kalkan covers the same core sunken-city circuit.

If you’d rather not manage logistics yourself, a full-day Kekova sunken city boat tour departing from Kaş covers the ruins pass, Kaleköy castle stop and swim breaks in one booking, and the equivalent boat trip from Kalkan runs a very similar route for travellers based there instead.

Kayak and canoe alternatives

For a more active, closer-to-the-water way to see the same coastline, several operators run kayak or canoe tours instead of the standard large group boat. These still respect the no-swimming-over-ruins rule but put you in a smaller, quieter craft that can approach some sections at water level rather than looking down from a boat rail.

A canoe tour from Kaş that includes a lunch stop is one option worth comparing against the standard boat trip, and a guided sea kayaking tour of the Kekova coastline suits travellers who want a slower, more physical pace over a full day on the water. These trips tend to run in smaller groups than the large day boats, which some visitors prefer for a calmer, less crowded feel around the ruins.

Combining Kekova with Demre and Myra

Kekova sits close enough to Myra and modern Demre that some operators fold both into a single day, pairing the boat trip with a look at the rock-cut tombs, Roman theatre and the Church of St Nicholas associated with the historical figure behind the Santa Claus legend. This suits travellers who want to cover more ground in one day and don’t mind a longer, fuller itinerary; it’s a reasonable option if your time on the Lycian coast is limited to a day or two. A combined tour taking in Myra, St Nicholas and the Kekova sunken city in one day is built for exactly this pairing.

The trade-off is pace: a combined day covers Myra’s ancient sites, the church in Demre, and the full Kekova boat circuit in the same window a dedicated boat day would spend entirely on the water. If seeing the ruins at a relaxed pace matters more than covering multiple sites, a standalone Kekova boat day is the better fit; if efficient sightseeing across a short Lycian coast visit matters more, the combined tour makes sense.

Departure variations: glass-bottom boats and private options

Beyond the standard group day boat, a few variations on the same basic Kekova circuit are worth knowing about before you book:

• Glass-bottom boats. Some operators run boats fitted with a glass panel in the hull, giving a clearer view of the submerged walls and staircases without needing to lean over the rail. A glass-bottom boat trip to the Kekova sunken city, combined with Demre and other Lycian ruins is one way to see the ruins this way rather than on a standard open-deck boat.
• Departures from Demre. Because Demre sits close to both Myra and the Kekova coastline, several tours start there instead of Kaş or Kalkan. A Kekova boat trip from Demre with swimming stops away from the sunken city follows the same no-swimming-over-the-ruins rule as boats from Kaş, just with a shorter transfer for travellers already staying near Demre.
• Smaller, private-style boats. For a quieter pace than a large shared boat, a private boat trip to Kekova from Demre with lunch and snorkelling at the swim stops covers the same core circuit — the ruins pass, Kaleköy, swim breaks — with a smaller group.

None of these variations change the underlying rule about the ruins themselves; the difference is in group size, the departure town, and how clearly you can see the submerged walls through the water.

Kekova as a longer day trip from Antalya or Alanya

Travellers based in Antalya city or further along the coast in Alanya sometimes ask whether Kekova is realistic as a single day trip from further away, rather than from Kaş or Kalkan themselves. It’s possible, but it’s a genuinely long day: the drive alone from Antalya or Alanya to the Kaş/Kalkan area takes several hours each way on the winding coast road, on top of the boat circuit itself.

Operators do run this as a packaged option. A day trip from Antalya covering Demre, Myra and the Kekova boat tour, and a similar Demre, Myra and Kekova day trip with boat cruise from Antalya, both bundle the road transfer with the same boat circuit described above, usually with an early departure to make the most of the day.

From further along the coast, a day trip from Alanya taking in Kekova, Demre and Myra with a boat tour covers the same ground for travellers staying near Alanya rather than on the Lycian coast itself.

Whether this makes sense depends on how much of your trip is based near Antalya or Alanya versus the Lycian coast. If Kekova is a priority and your schedule allows it, staying a night or two in Kaş or Kalkan and doing the boat trip from there — rather than adding a long transfer on both ends of a single day — tends to leave more time actually on the water rather than on the road. Travellers planning a longer loop along this stretch of coast may find it worth comparing against a dedicated Lycian coast itinerary that builds in a base closer to Kekova rather than a single long day trip.

Day trip vs. part of a wider Lycian coast tour

Kekova is often sold two different ways, and it’s worth being clear on which one you’re booking:

1. A dedicated Kekova boat day — the whole day is built around the boat circuit: the ruins pass, Kaleköy, swim stops and lunch on the water. This is the better choice if the boat experience itself is the priority.
2. Kekova as one stop within a broader Lycian coast tour — some itineraries pair a shorter Kekova segment with land-based stops elsewhere on the coast, such as Kaputaş Beach or Patara. This suits travellers who want variety across a single day rather than a full day on one boat.

Whichever route from Antalya or the wider region you’re travelling from, it’s worth checking current road conditions and journey times for the specific route and season rather than assuming a fixed duration — the coast road out to Kaş and Kalkan is scenic but winding, and travel times can run longer than a flat map distance would suggest.

Practical tips for visiting Kekova

• Set expectations before you book. No swimming or diving over the ruins is the single most important thing to know going in — read the previous sections again if this is the deciding factor for you.
• Bring reef-safe sun protection. Much of the day is spent on open water with little shade; a hat, sunglasses and a reapplied sunscreen matter more here than on a shaded inland tour.
• Wear or pack proper footwear for Kaleköy. The climb up to the castle at Simena involves uneven paths and some steps.
• Pack a swimsuit regardless. The designated swim stops away from the ruins are genuine swimming opportunities, and the water in these bays is typically calm and clear.
• Check the cancellation policy for wind. Boat trips in this area can be affected by strong wind; most reputable operators offer rescheduling or refunds if a trip is cancelled for weather.
• Bring cash in small denominations. Harbour villages like Üçağız and Kaleköy have small stalls and cafés where card payment isn’t always available.

Kekova sunken city: frequently asked questions

Can you swim or dive at Kekova’s sunken city?

No. Swimming and diving directly over the submerged ruins are prohibited by law to protect the site. Boats pass slowly over the clearest sections so passengers can look down through the water; separate swim stops happen at nearby bays away from the ruins.

Where do Kekova boat trips depart from?

Most day boats depart from Kaş or Kalkan, both a short drive from the Kekova area on the Lycian coast. Some tours also depart from Üçağız, the small harbour village closest to the sunken ruins, or combine Kekova with a stop at Demre.

How long does a Kekova boat trip take?

A typical day trip runs around 6 to 8 hours, including the boat’s slow pass over the sunken ruins, a stop near Simena/Kaleköy castle, and usually one or two swim breaks in open bays away from the protected area.

Is Kekova worth visiting if you can’t swim over the ruins?

Most visitors who go in with the right expectation find it worthwhile — the setting is scenic even beyond the ruins, combining a hilltop castle, a half-submerged village, calm turquoise water and quiet bays. Visitors expecting a snorkel-the-ruins experience tend to be the disappointed ones, which is why understanding the no-swimming rule beforehand matters.

What is Kaleköy (Simena) and is it part of the same trip?

Kaleköy, also known as Simena, is a small village built around a hilltop Crusader-era castle overlooking the sunken city area. It is reachable only by boat or on foot, and almost every Kekova boat trip includes a stop here, usually with free time to climb to the castle for the view.

Can Kekova be combined with other Lycian coast sights in one day?

Yes. Some operators pair Kekova with Kaş town, Kaputaş Beach, or a wider Lycian coast itinerary, while others run it as a standalone boat day. Comparing a dedicated Kekova boat day against a broader Lycian coast tour is worth doing before booking, since the two options suit different priorities.

Do you need to book a Kekova boat trip in advance?

In peak summer months it’s sensible to book at least a day or two ahead, since popular boats fill up. In shoulder season, same-day or next-day bookings from Kaş or Kalkan harbour are often possible, though availability varies by operator and group size.
