Deluxe Sunken City Boat Guided Tour From Kas
Kekova’s Sunken City ruins are best understood from the water, where broken walls and ancient stonework sit just below the surface beside the island. This full-day trip from Kas combines that unusual view with swimming stops, snorkeling equipment, lunch, and a visit to Simena Castle. Captain Mustafa and his wife host the boat, which is limited to eight people.
I like the small group, since eight passengers gives you more room than a crowded day boat. I also like that the day leaves time for both history and swimming, rather than rushing from one photo stop to the next. The main consideration is price: at $241.36 per person, this is a serious splurge, and drinks are not included.
Key points at a glance

- Sunken ruins from the sea: You’ll see the submerged remains of Kekova from the boat, with time set aside for swimming near the island.
- A small boat group: The maximum is eight people, a useful detail for anyone who dislikes packed excursions.
- Simena Castle on foot: You get one hour at Kaleköy to climb to the castle or buy homemade ice cream on the island.
- Lunch is included: Food is covered, but bottled water, soft drinks, tea, coffee, and alcohol cost extra.
- Snorkeling gear supplied: You do not need to bring your own equipment, though the itinerary does not promise that every ruin can be explored underwater.
- Weather matters: Poor conditions can lead to a new date or a full refund.
Why Kekova is worth seeing from a boat

Kekova is not a standard archaeological site with gates, signs, and a walking path. Much of its appeal comes from the odd sight of history meeting the sea. Ancient ruins lie partly submerged around the island, so the boat becomes your viewing platform.
The most important expectation to set is this: you will see the Sunken City from the boat, and you will have time to swim and snorkel nearby. This is not presented as an underwater archaeological tour where you swim through the ruins. The boat lets you look down into the water while the guide points out the remains.
That approach has a practical advantage. You can see the scale and setting of the ruins without spending the day on a hot stone site. The water also gives you a way to break up the historical stops, which matters on an eight-hour outing in the Mediterranean sun.
The tour passes near a small pebble beach as part of the route. It is a brief scenic point rather than a listed long stop, but it adds another change of view during the day.

The two-hour Kekova Island stop

The main stop at Kekova Island lasts about two hours. This is where you have time for swimming and for seeing the Sunken City area at a slower pace.
The swimming stop is one of the strongest parts of the trip for anyone who wants a boat day rather than a history lesson on water. Snorkeling equipment is included, so you can look below the surface without renting gear separately. Still, the supplied details do not specify the type or condition of the equipment, so you may prefer to bring your own mask if you already have one and care about fit.
The underwater view depends on the sea and the light. Clear conditions make submerged stonework easier to spot, while wind or choppy water can limit what you see. Since the tour requires good weather, the operator can move the booking to another date or issue a full refund if conditions are poor.
The two-hour window is generous by boat-tour standards. You should have enough time to swim, use the snorkeling gear, dry off, and pay attention to the ruins without feeling that the captain is calling you back after a few minutes. The tradeoff is that you will spend a large part of the day outdoors, so sun protection and a way to keep drinking water are sensible priorities.
Seeing the Sunken City without touching it

The submerged ruins are viewed from the boat. That distinction matters because visitors sometimes picture a free-swimming archaeological site where they can explore every wall at close range. This experience offers a look from the surface and a swim in the surrounding water, not unrestricted access to the ruins.
From the boat, the setting is the attraction. You see the coast, the waterline, and old stone remains together. The result is more atmospheric than a conventional ruin visit, but it also asks you to pay attention. If you expect large, clearly labeled monuments, the view may feel subtle.
I would treat this part as a chance to slow down and look carefully. The boat’s position, the water clarity, and your seat all affect what you can see. A small group helps here because the experience is less likely to feel like a mass photo stop, and you can ask Captain Mustafa about what is in view.
Snorkeling adds another angle, but it should be treated as an optional pleasure rather than the only reason to book. The tour provides equipment and swimming time, while the most definite archaeological viewing is from the boat.
Kaleköy and the one-hour climb to Simena Castle

The second named stop is Castle of Simena, also associated with Kaleköy. You have about one hour on the island, which gives you a choice: climb to the castle or stay lower down and enjoy homemade ice cream.
That choice makes the stop work for different energy levels. The castle climb suits you if you want a better view and another dose of ancient stonework. It is not a long visit, though, so you will want to keep an eye on the time. The one-hour stop is enough for a focused visit, not a leisurely exploration of every corner.
If you would rather keep the afternoon easy, homemade ice cream offers a simpler reward. This is the sort of small local detail that keeps a boat excursion from becoming a string of formal monuments. You can make the stop active, relaxed, or split the difference.
The admission ticket for Simena Castle is not included. This is a minor extra compared with the tour price, but you should carry some money if you want to enter. The supplied details do not state the admission cost, so do not assume it is covered or that the price is fixed at the time you visit.

Lunch, drinks, and the real cost of the day

Lunch is included, which helps justify part of the $241.36 price. You are not paying for eight hours on the water and then buying a separate meal at a port. The experience also includes fuel and snorkeling equipment.
The food can be a highlight. On one outing, Captain Mustafa and his wife served a multi-course lunch followed by dessert, tea, and fruit. That gives you a useful idea of the hosting style, but it should not be treated as a guaranteed menu. The official inclusions say lunch only.
Drinks are the main extra expense to plan for. Bottled water, coffee, tea, soda, and alcohol are not included. The safest approach is to budget for drinks before departure and confirm what is available on the boat. The tour details do not state that outside drinks are permitted, so ask the operator rather than assuming.
At this price, I would compare the tour with ordinary group boat trips in Kas. The value is not simply the number of stops. You are paying for a small maximum group of eight, an eight-hour route, lunch, fuel, and a host-led outing around a site that is difficult to appreciate from land. If you only want a quick swim, this is too expensive. If you want a full day with swimming, ruins, food, and a small group, the cost makes more sense.
What the small group changes

A maximum of eight people is one of the clearest reasons to consider this outing. A smaller group usually makes boarding, eating, and moving around the boat less awkward. It also gives you a better chance to hear the guide when the boat is near the ruins.
The boat itself is described as having plenty of places in sun and shade. That matters on an eight-hour trip. You can choose full sun for part of the ride, then retreat to shade when the heat catches up with you.
The group size may also suit families. A family of four with two teenagers found the boat comfortable, with room for both sun and shade. That is helpful evidence for families who want a full day on the water without committing to a large cruise boat.
Still, a small group does not mean a private charter unless the operator specifically confirms that arrangement. You share the boat with other people, and the route remains subject to weather and the minimum number of participants.
The boat-day rhythm: views, swimming, and lunch

The appeal of this trip is its changing pace. You begin with open-water views and a breeze, pass the small pebble beach, stop around Kekova Island, and then make time for Simena Castle. The day is not built around constant narration or nonstop sightseeing.
Four swimming stops were made on one reported outing, although the supplied itinerary specifically identifies the Kekova Island swimming stop and does not promise four stops every time. That distinction is worth keeping in mind. You should expect swimming, but ask the operator about the exact route if the number of bays matters to you.
The boat gives you a better sense of the coast than a quick visit from Kas. You see the ruins in their setting and have time to notice how the shoreline changes. The breeze is welcome, but it can also make the day feel cooler on the return ride, so a light layer is useful if you are sensitive to wind.
Lunch helps mark the middle of the day. Since only lunch is included, you should think of the meal as part of the package rather than an all-inclusive arrangement. The food served on one outing was generous and included several courses, dessert, tea, and fruit, but menus can vary.
Who will get the most from this tour

I would recommend this tour to you if you want a full day on the Mediterranean with a clear mix of water time and ancient sites. It is particularly well suited to:
- Couples or families who prefer a small group
- Swimmers who want included snorkeling gear
- History-minded visitors who enjoy seeing ruins in an unusual setting
- People who like a flexible stop, with a castle climb or homemade ice cream
- Anyone who values lunch and fuel being part of the upfront cost
I would be more cautious if you dislike boats, cannot comfortably spend eight hours outdoors, or want a tightly scheduled archaeological tour with detailed access to every ruin. The Sunken City is viewed from the boat, and the castle stop is only one hour.
The tour is also a better fit if you are comfortable with extra drink costs. Since water and other beverages are excluded, the advertised price is not the final amount for everyone.
Booking, weather, and practical details
Confirmation is provided when you book, and the experience is offered in English. It is near public transportation, and most people can participate according to the supplied activity details.
The experience is commonly booked about 28 days in advance. That does not guarantee that every date sells out, but it is a useful sign that you should not leave this to the last minute if your Kas schedule is fixed.
The maximum group is eight people. The experience also requires a minimum number of participants. If that minimum is not met, the operator can offer another date or experience, or provide a full refund.
Cancellation is flexible if you act early. You can cancel for a full refund up to 24 hours before the start time. Cancellations or changes made less than 24 hours before departure are not accepted for a refund, and the cut-off follows local time.
Weather is the key variable. Poor weather can cancel the outing, in which case you are offered another date or a full refund. That policy is reassuring for a boat route where swimming and clear views matter.
Should you book the Kas to Kekova boat tour?
Book it if you want a small-group day on the water that combines swimming, snorkeling, lunch, Kekova’s submerged ruins, and an hour at Simena Castle. The strongest reasons are the group limit of eight, the generous two-hour Kekova stop, and the chance to choose between climbing to the castle and eating homemade ice cream.
Skip it if you mainly want a cheap swim or if your priority is a long, detailed visit inside archaeological sites. At $241.36 per person, the tour needs to deliver more than transportation, and its value comes from the full package: boat time, hosting, lunch, fuel, equipment, and access to a hard-to-see coastal site.
Before you go, budget for drinks and the castle admission, and confirm the day’s swimming plan. If those extras and the price fit your plans, this is a well-rounded way to experience Kekova from the water rather than simply looking at it from shore.
