Underwater ruins, on a sunny boat day. I love how this trip pairs multiple swim stops with unforgettable views of Kekova’s Sunken City Ruins, right from the boat. The only real watch-out is the day can be less smooth on the English side than you might expect, and one advertised detail (a glass-bottom option) may not match what you actually see.

The best part is how the ruins and villages share the same route. You’ll cruise by the flooded ancient city, then anchor in Kaleköy (ancient Simena) for a short walk with big sea views, plus some time to swim again before heading back to Kaş.

Key highlights

• Aquarium Bay: a full hour swim break next to Kekova
• Sunken City Ruins: see the flooded Dolchiste remains from the boat (no swimming there)
• Burç Bay: cooler water thanks to underwater springs, plus another swim stop
• Pirates Cave: a naturally formed cave with a curved entrance
• Kaleköy (ancient Simena): one hour in the village for castle and necropolis ruins
• Lunch included: you’re covered for food once you’re out on the water

Why Kekova looks better from the water

Kekova has a specific magic. You’re not just looking at ruins, you’re moving past them, floating over the coastline where history slid under the sea. From the boat, you get those classic views that make people stop talking and just point.

What I like most is that the day is built around time in the water. You get several swim breaks in different bays, so even if you are not a ruins person, the sea views and clear conditions usually win you over.

And yes, the flooded city is the headline. The ancient city of Dolchiste was flooded after an earthquake in the 2nd century, and the resulting underwater remains are protected, so the experience focuses on sightseeing by cruise rather than swimming in the ruins.

Getting from Kaş to Uçakız and out onto the water

This tour starts with a Kaş pick-up and a transfer to the harbor, where you board the boat. Your car is parked outside Smiley’s Restaurant, and pickup times can vary by season, so you’ll get the exact timing the day before by WhatsApp or email.

The boat departs the Uçakız/Demre harbour between 10:20 and 10:40 am. That matters because the timing usually affects how bright the water looks in photos, and how early you get to your first swim.

The ride is the “connected tissue” of the day. You’re not stuck moving nonstop, because the schedule includes swim breaks that break up the long, scenic stretches across the water.

Aquarium Bay: the hour-long swim break that sets the tone

If you only remember one stop, make it Aquarium Bay. You get a one-hour swim break, and it’s positioned right by Kekova, so the views and the water happen together.

A full hour is a big deal on boat days, where many itineraries feel like you get 20 minutes and that is it. Here, you get enough time to actually relax, cool off, and swim without rushing.

Practical tip: this is not the moment to wear “nice” shoes. You’ll want a quick on-and-off setup, and you’ll appreciate having a towel ready for after you haul yourself back on board.

Sunken City Ruins: what you’ll see, and what you won’t be doing

This is the core experience: Kekova Island and the Sunken City. The tour takes you around the protected area, giving you a chance to cruise alongside the underwater remains and capture photos from the boat.

The key rule is simple: swimming is not permitted in the protected ruins area. That might sound like a limitation, but it actually helps you understand what the tour is doing. Instead of encouraging you to wade where you can damage fragile sites, you get the panoramic view and the “history under the water” perspective.

You’ll also hear the story behind the ruins: Dolchiste was flooded in the 2nd century, and the underwater remains have stayed visible enough to make the cruise feel like you’re watching archaeology in real time.

If you’re someone who likes making sense of what you’re looking at, this is one of those days where you can get plenty out of simply watching the coastline slide by slowly.

Burç Bay, Pirates Cave, and the cool-water contrast

After Aquarium Bay, the itinerary keeps bouncing between swims and sights. Burç Bay is another swim stop, and one detail worth knowing is that the sea can feel cooler here due to cold underwater natural springs.

That contrast can be great. After a warmer swim, cooler water can feel refreshing rather than harsh, and you often notice the temperature shift quickly when you first step in.

Then comes Pirates Cave. This one is naturally formed, known for its large size and a curved entrance. You won’t be climbing into it like a movie scene, but you will get the visual payoff of a landmark-shaped cave along the coast.

These stops are also good for non-swimmers. Even if you skip a swim, you still get the scenery, the changing shoreline, and a sense of where Kekova’s bays meet its cliffy edges.

Gökkaya Bay lunch and the water-sports option

Lunch happens during the Gökkaya Bay stop, paired with time to swim. This is where you get a more break-like moment in the day, not just short dips between cruises.

The lunch is included, and you’ll likely appreciate that on a long boat day. Out here, you’re spending hours in sun and water, so having food covered means you are not scrambling for snacks or paying extra for basic meals later.

You can also opt into water sports offered during the stop. The tour does not require you to do anything extra, but if you like trying something active, this is the place where it’s most likely to be available.

If you get motion-sick easily, plan to eat slowly and give your stomach a moment after you settle. Boat days can be smooth, but the coastline stops and starts can still make you feel it.

Esmeralda Bay: calm swimming before the final village stop

After Gökkaya, the day continues with Esmeralda Bay, where the plan is another swim stop. This one is described as a chance for peace and tranquility, which usually means less of the “rush to jump in” vibe and more of a hang-out feeling.

This is also a good stop for taking breaks from the constant swim schedule. Even if you swim, you can treat it like a recovery moment, stretch your legs, and reset before the land portion of the itinerary.

Kaleköy (ancient Simena): castle ruins, necropolis, and a short hike

Your boat anchors in Kaleköy port for about one hour. This is ancient Simena, and it’s a chance to swap the boat deck for real village streets.

You can visit castle ruins and a necropolis in the area. There’s also a hike up the hillside for views across the Kekova region, and those views are often the kind you remember long after you’ve stopped checking your phone.

If you’d rather keep it easy, you might be able to admire Simena Castle from down below during your remaining time, including using time for another quick dip.

One thing to know: you may need cash for the castle. I’d come prepared with some small bills just in case, especially if you expect smooth entry without searching for an ATM at the last second.

Price and value: why $57 can feel fair here

At around $57 per person, this day trip is priced like a real boat experience, not just a basic sightseeing transfer. The value comes from the full package of:

• Multiple swim stops across several bays
• Sunken City ruins views from the boat
• A village stop with ruins and scenery
• Lunch included

Drinks are not included, so if you’re the type who drinks a lot of water or wants soda or juice on a hot day, budget a bit extra. This is also why packing your own water plan (where permitted) can help, but the key fact here is only that drinks are not part of the included price.

The other value angle: the boat schedule gives you a sense of place. You’re not just viewing Kekova from one spot, you’re moving past it, which is exactly how the coastline makes sense.

What to bring, and what to plan for

You’ll want to show up ready for sun and water. The essentials are:

• Comfortable shoes
• Sunglasses
• Sun hat
• Towel

Also keep in mind the day is not a great fit for everyone. This tour is not recommended for people with limited mobility. If stairs, uneven ground, or getting back onto a boat is a challenge for you, it’s best to look for a more accessible alternative.

Rules-wise:

• No pets
• No alcohol and drugs

And about the language experience: English is listed as part of the host or greeter setup, but it’s smart to be practical about expectations. On at least some departures, translation may be handled with help from other people, so if you need detailed commentary in English, confirm what kind of English support will be available before you commit.

Who this boat day fits best

This is a great choice if you want the Kekova highlights without building your own route. The itinerary packs a lot of variety into one day: cruises, caves, swim bays, and the Kaleköy ruins stop.

It also works well for couples and solo travelers who like a shared day on the water. Small-group style boating tends to feel more comfortable on long trips, and the overall flow is geared toward making the most of swimming time.

What might not fit as well:

• If you specifically want a glass-bottom boat experience, know that it may not be part of what you get. I’d treat any glass-bottom promise as something to verify.
• If you strongly care about having a fluent English guide onboard, confirm the setup ahead of time rather than assuming it will be fully narrated in English.

Should you book this Kaş to Kekova day trip?

If you want a classic Kekova experience with real time on the water, I think this is an easy yes. The combination of Sunken City views, hour-long Aquarium Bay swim, and the Kaleköy castle and necropolis stop makes it feel like a full day worth the effort.

Book it if:

• you like swimming and want multiple chances to cool off
• you care more about views than museum-style pacing
• you want lunch handled, not chased

Consider a different option if:

• you need a fully accessible itinerary
• you are depending on a guaranteed English-speaking guide or a specific boat type, like a glass-bottom setup

If you do book, show up with sun protection, a towel, and some cash for the castle just in case. Then sit back and let the coastline do the talking, because that’s really why this trip works.
