From Demre: Day Trip to Kekova by Boat
Kekova is best seen from the water, where ancient ruins, clear swimming coves, and small coastal villages fit into one long Mediterranean day. This seven-hour boat trip from Demre combines the area’s main sights with plenty of time for swimming, rather than rushing from one photo stop to the next.
I like the balance here: Simena Castle and the Sunken City provide real history, while Esmeralda, Burç, and Gökkaya bays give you long breaks to swim. Lunch is included, and the crew also serves snacks, according to the detailed tour feedback. The main consideration is the group size, which can reach 55 people, and the inconsistent information about the Simena Castle entrance fee, listed as both €1 and €4.
Key points
- Seven hours on the Mediterranean: You leave Andriake Harbour around 10:30 am and return to the same meeting point.
- Sunken City views without swimming: The protected ruins of ancient Dolchiste are seen from the boat.
- One hour at Kaleköy: Use the stop for Simena Castle, the hillside views, the village, or a swim below the ruins.
- Three strong swimming stops: Esmeralda Bay, Burç Bay, and Gökkaya Bay each offer a different setting.
- A real chance to spot turtles: Karemlik Bay is known as a place to look for Mediterranean sea turtles.
- Lunch included: Your meal is served during the bay stops, helping make the $60.01 price easier to justify.
Why a Boat Is the Right Way to See Kekova

The Kekova coast is scattered with small coves, steep hills, old settlements, and ruins partly hidden below the sea. From land, you can reach a few points, but the boat gives you the broad view: one hour you are looking at a Byzantine-era castle, and the next you are swimming in water clear enough to see below the surface.
The most unusual sight is the Sunken City of Simena, also known as ancient Dolchiste. An earthquake in the second century flooded part of the settlement, leaving stone remains beneath the water. You cruise beside the ruins, taking photographs from the deck.
This is not a snorkeling stop. The site is protected, so swimming is not allowed near the Sunken City. That restriction may disappoint anyone hoping to get close to the ruins underwater, but it protects a fragile archaeological area and keeps the boat visit simple. Bring your camera, but do not expect an underwater exploration.
The tour runs in summer, when warm weather makes a full day on deck and repeated swims appealing. The same sun that makes the sea inviting can also make the open boat tiring, so sunscreen, a hat, and water are practical essentials.

Starting at Andriake Harbour Around 10:30

You meet at Andriake Harbour, near Demre, and the boat departs at about 10:30 am. The schedule allows a full day without an early morning start, which is useful if you are staying in Demre or arriving after a slower breakfast.
The published timing also refers to departure between 10 and 10:30 am, so arrive in good time rather than treating 10:30 as a guaranteed boarding minute. The activity ends back at the same harbour after the day on the water. From there, you can head into Demre for dinner or continue to your next destination.
The group may include up to 55 people. That is worth considering before booking. A larger boat can offer a more social day and may feel steadier for anyone concerned about seasickness, but it also means that prime deck seats and quiet corners may be limited. One detailed account specifically found the trip comfortable even with seasickness concerns, though your experience will depend on the day’s sea conditions.
The tour is offered in English. No guide names are provided, so you should not book this expecting a named private guide. Instead, expect crew commentary about the places along the route, with lunch and snacks handled onboard.
Kaleköy and the Climb to Simena Castle

The first major stop is Kaleköy, ancient Simena. The boat anchors in the small port for about one hour, giving you time to choose between land and water.
On land, you can walk through the authentic village and climb toward Simena Castle. The hillside position gives you wide views across the Kekova area, with the coast and nearby islands spread below. The climb is the best use of your hour if you want scenery and old stonework rather than another swim.
The castle itself is modest, not a vast fortress complex. Its appeal comes from the location, the remains, and the nearby necropolis. You are seeing a small historic settlement in its coastal setting, not a polished museum attraction.
You can also split the hour. Spend roughly 30 minutes walking uphill, then return to the water for a swim while the boat remains in the area. The schedule presents the castle and the water as separate 30-minute options, so do not assume you have unlimited time for both.
There is a fee for Simena Castle, and the supplied tour details conflict: one section gives €1, while the inclusion information states €4 per person. Treat the entrance as extra and confirm the current amount before you go. Bring a little cash in euros if possible, since the fee is not included in the tour price.
Seeing the Sunken City from Deck Level
After or around the Simena stop, the boat passes the Sunken City ruins. This is one of the reasons to choose a Kekova boat outing instead of a standard swimming cruise.
You will see traces of the flooded settlement from the boat, including remains along the waterline and below the surface. The best photographs depend on your position, the sun, and how close the boat can safely pass. Keep your camera ready, but remember that this is a moving viewpoint, not a long shore visit.
The no-swimming rule is important. You cannot get into the water at the ruins, and you should not expect the boat to stop for a snorkeling session there. Instead, the day gives you separate swimming stops where you can enjoy the sea without entering the protected archaeological zone.
I like this arrangement. The historic portion remains focused and respectful, while the recreational part of the day takes place in coves meant for swimming. You get both experiences without forcing them into the same stop.

Esmeralda Bay: Lunch and a Quiet Swim

The boat then reaches Esmeralda Bay, described as a peaceful place for lunch and swimming. This is a good transition in the day. After the castle walk and the Sunken City viewing, you can settle into a slower stretch of open water.
Lunch is included, which matters at this price. You are not spending extra time looking for food on shore, and the meal is served while the boat is already in the bays. The available feedback describes the lunch and snacks positively, with the crew taking care in preparing and serving them.
Do not expect a restaurant meal or a choice-filled menu unless the operator confirms otherwise. The value is convenience: food is part of the trip, and you can eat without giving up sightseeing time.
Esmeralda Bay also gives you a quieter swim stop. If you prefer to float, sit in the sun, or simply enjoy the view from the boat, this is likely one of the more relaxed sections of the route. The description does not specify beach access, so plan to swim from the boat rather than expecting a long shore break.
Burç Bay and the Noticeably Cooler Water

Lunch is followed by about 40 minutes at Burç Bay. The water here is cooler because of natural underwater springs. That detail is useful, especially if you prefer warm water or plan to swim several times during the day.
The cooler sea can be refreshing after sitting in the sun, but it may also shorten your swim. You do not need to force yourself into the water. The boat gives you a place to rest, take photographs, and watch others enjoy the cove.
This stop adds variety to the route. The bays are not presented as identical swimming breaks. Esmeralda is linked with peace and lunch, Burç with spring-cooled water, and Gökkaya with water sports and a broader activity feel.
Because the tour spends several hours on the water, these differences help keep the day from feeling repetitive. You can swim when the conditions suit you and stay onboard when they do not.
Gökkaya Bay and the Most Active Stop

Gökkaya Bay is the liveliest swimming stop on the route. You have time to swim and may also choose from various water sports offered in the bay. The exact activities and prices are not specified, so ask the crew what is available and what costs extra before committing.
The stop is part of a roughly two-hour section that includes Esmeralda Bay, Burç Bay, and Gökkaya Bay. That is a generous amount of time for the recreational part of the trip. You are not simply jumping into the water for ten minutes before being called back onboard.
Gökkaya suits you if you want more than sightseeing. It is also a practical stop for families or groups with different interests, since some people can swim while others rest on the boat. Just keep in mind that the tour’s maximum group size is 55, so water activities may feel busier than a private charter.
The sea is the star here. Bring swimwear you can comfortably wear for much of the day, and consider carrying a dry layer for the ride back. The available information confirms lunch and snacks, but it does not specify towels, changing rooms, lockers, or showers, so do not count on those extras unless SAILNSTAY confirms them.
A Natural Cave Along the Coast

The route also includes a naturally formed cave with a large size and curved entrance. The supplied details do not give it a name or a separate stop length, so think of it as a sightseeing passage rather than a long cave visit.
This kind of stop works well from a boat. You can photograph the unusual opening without spending time on a difficult walk or shore landing. The cave adds another visual change to a day already filled with ruins, bays, and village views.
Since no swimming or walking inside the cave is specified, do not plan around an interior exploration. It is best treated as a short scenic feature during the cruise.
Karemlik Bay and the Search for Turtles

Near the end of the route, the boat reaches Karemlik Bay, where you can look for turtles in their natural habitat. Five of the world’s eight known turtle types are found in the Mediterranean, according to the tour information, but seeing one is not guaranteed.
That uncertainty is part of the appeal. You are not visiting a display or feeding station. You are watching the water and shoreline, hoping for a glimpse of a wild animal. One account of the trip did see turtles, which makes this a worthwhile possibility, but you should not make the entire booking decision on a sighting.
Bring patience. Keep your eyes on the water, listen for instructions from the crew, and have your camera ready without expecting a perfect close-up. Karemlik Bay is a calmer finish after the active swimming section and gives the day one last natural highlight.
What the $60.01 Price Buys You
At $60.01 per person, the price is reasonable for a seven-hour boat day that includes lunch and several swimming stops. You are paying for a full route around Kekova rather than a short harbor cruise, and the historic stops would be difficult to combine independently without arranging your own boat.
The value is strongest if you want variety. You receive:
- A boat ride along the Kekova coast
- Views of the protected Sunken City
- Time at Kaleköy and Simena Castle
- Swimming at Esmeralda, Burç, and Gökkaya bays
- A chance to see turtles at Karemlik Bay
- Lunch and snacks onboard
- An English-language experience
The price does not include the Simena Castle entrance fee. Because the supplied information lists both €1 and €4, confirm the current price before departure. Water sports at Gökkaya Bay may also carry their own charge, since they are described as optional activities and no price is given.
For a private, quiet boat experience, this is not the right comparison. The group can reach 55 people. For a shared day with a long route, food, swimming, and major Kekova sights, the cost is easier to defend.
Who Will Enjoy This Day Most
I would choose this trip if you want to see the main Kekova sights but also want a proper swim day. It suits couples, families, and small groups who prefer a ready-made route over arranging separate boat transport.
It is especially useful for you if:
- You are staying in or near Demre
- You want historic sights without giving up beach time
- You enjoy swimming in clear coastal water
- You like the idea of a possible turtle sighting
- You prefer lunch included rather than finding food during the day
- You are comfortable sharing a boat with as many as 55 people
You may want another option if you need a private boat, dislike long periods in the sun, or want to swim directly beside underwater ruins. The Sunken City is viewed from the boat, and the protected area does not allow swimming.
The tour is also weather-dependent. If poor weather forces cancellation, you are offered a different date or a full refund. Free cancellation is available up to 24 hours before the start time, while late cancellations and last-minute changes are not accepted.
Should You Book the Kekova Boat Trip?
Book it if you want the best mix of Kekova history and Mediterranean swimming in one day. The seven-hour schedule is long enough to avoid the rushed feeling common on short boat tours, and the included lunch adds real value to the $60.01 price.
The strongest reasons to go are the Sunken City viewpoint, the one-hour Kaleköy stop, the several swimming bays, and the chance to see turtles. The main tradeoff is a potentially full boat, plus the extra castle fee and the unclear price difference in the supplied information.
If that balance works for you, this is a sensible way to experience Kekova from Demre. Arrive at Andriake Harbour on time, confirm the castle fee and any optional water-sport charges, and plan for a sunny day spent mostly on deck and in the sea.
