Kas: Full-Day Boat Tour with Lunch
Kas is at its best from the water. This full-day boat trip trades the town’s busy waterfront for quiet bays, clear turquoise swimming spots, and a long stretch of open sea. You’ll snorkel around Twelve Isles, look for fish near underwater canyons, and see the odd sight of a shark statue beneath the water at Guvercin Island.
I like the mix of active and easygoing stops. You can use the provided snorkel equipment, visit a local bat cave with the guide, or simply stretch out on deck with the sea breeze. I also like that lunch is included, with olive-oil-based dishes served aboard the yacht. The main drawback is simple: drinks are not included, hotel pickup is not included, and you must reach the marina by 9:30am.
Key points at a glance
- Twelve Isles brings the best snorkeling: Look for fish around a shipwreck and underwater canyons.
- Yarilgan Bay starts the day gently: Swim from the boat, snorkel, or visit a bat cave with the guide.
- Guvercin Island has the unusual photo stop: Swim above an underwater shark monument after lunch.
- Lunch is part of the $83 price: Expect an organic meal built around Turkish dishes and olive oil.
- The day lasts about 8 to 9 hours: You return to Kas marina after two final swims at Harbour Mouth Bay and Big Pebble Beach.
- Plan your own way to the harbor: Hotel pickup and drinks are not included, and arrival is required by 9:30am.
Leaving Kas for a day on the water

You meet the team at Kas marina at 9:30am. A team member is due to share the final trip details one day before departure, but you should still plan your morning carefully. Since hotel pickup is not included, give yourself enough time to reach the harbor without a last-minute dash.
The tour is described as a private-group experience, with English and Turkish available from the host or greeter. One recent booking described a full boat that still had enough room to move around comfortably, so the exact feel may depend on the departure. If having a fully private yacht matters to you, ask Akhilleus Tourism what private group means for your booking before paying.
The boat day lasts around eight hours, sometimes closer to nine. That is long enough to make the trip feel like a proper day away rather than a quick swim cruise. It also means you should be honest with yourself about comfort at sea. There is plenty of time for swimming and sun, but little reason to book this if you prefer a tightly scheduled sightseeing tour on land.

Yarilgan Bay and the bat cave

Yarilgan Bay is the first stop, and it sets the tone for the day. You can enter the water for a swim, use the available snorkel equipment, or remain on deck. The bay has small fish and underwater sights, though the experience depends on water clarity and how active the marine life is on the day.
The bat cave adds a small sense of adventure. You do not have to visit it, and the guide can accompany those who want to go. That makes this a useful early stop because it offers more than a standard swim without forcing everyone into the same activity.
I would bring your own mask if snorkeling quality matters greatly to you, since the tour only states that equipment is available, not what type or how much is supplied. Still, for casual swimmers, the included equipment removes one item from your packing list.
The first stop also gives you a chance to settle into the boat’s rhythm. You can swim, look beneath the surface, or simply enjoy the view. This flexibility is important on a full day at sea. You are not expected to spend every minute in the water.
Twelve Isles, shipwrecks, and underwater canyons

Twelve Isles is the main snorkeling stop. The area is known for fish in different shapes and colors, along with a shipwreck and underwater canyons that provide shelter for sea life. You should not expect a formal guided underwater tour, but there is plenty here to keep a curious swimmer busy.
This is likely the most rewarding stop for anyone booking the trip mainly for snorkeling. The wreck and canyons give the seafloor more character than a plain sandy bay. They also create places where fish gather, although conditions can vary with the weather, visibility, and the number of boats in the area.
You can swim at your own pace, then return to the boat for a break. The tour is not built around constant activity, which I consider a plus. You can dry off on deck, enjoy the sun, and watch the coast pass by without feeling you are missing a scheduled attraction.
Bring a towel and camera, as requested, but protect your camera carefully around the water. Cash is also useful for the day, especially since drinks are not included. Food and drinks from outside are not allowed, so do not plan to bring a cooler or packed lunch aboard.
Lunch at Guvercin Island
Lunch is served at Guvercin Island, in a calm bay where the boat can pause for a more relaxed meal. The meal is included in the price and is described as organic, with olive oil playing a central role in the dishes. That points toward the sort of simple Turkish cooking that suits a hot day at sea: vegetables, salads, and other filling dishes rather than a heavy restaurant-style meal.
Recent bookings praised both the taste of the food and the service on the boat. Melons were also mentioned, a welcome touch after hours in the sun. You should still bring realistic expectations. This is a boat lunch, not a long restaurant meal with a broad menu, and dietary details are not provided.
Guvercin Island has one of the tour’s strangest features: an underwater shark monument. After lunch, you can swim above it and take underwater photographs. It is a deliberately odd attraction, but that is part of its charm. Most swimming bays begin to blend together during a long boat day, while a submerged statue gives you something specific to look for.
The stop works well because it combines food, swimming, and a memorable photo opportunity. You can eat first, then cool off in the water. If you are not comfortable snorkeling, you can still enjoy the monument from above if visibility allows, but the tour does not promise how close every swimmer can get.

The afternoon route and the possible Kekova connection

The published route continues toward Harbour Mouth Bay and Big Pebble Beach. These are final swimming and rest stops as the boat slowly returns toward Kas marina. Both are described as places of natural beauty, and they give you two more chances to enter the water without adding another major activity to an already full day.
Big Pebble Beach is close to Kas and makes a practical closing stop. After a long day away from town, it feels good to be nearing the harbor while still having time for one last swim. Harbour Mouth Bay offers the same kind of pause, with the emphasis on calm water, scenery, and relaxation rather than a formal attraction.
There is one detail worth clarifying before booking. A recent experience account described a stop at Kekova, including time to walk around a small village and buy ice cream, as well as a visit to the sunken city. Those details do not appear in the main route provided for this tour, which names Yarilgan Bay, Twelve Isles, Guvercin Island, Harbour Mouth Bay, and Big Pebble Beach.
It may reflect a different departure, a route change, or a separate version of the boat day. Do not book this trip solely expecting Kekova or the sunken city. If those are your priority, confirm the exact route with Akhilleus Tourism before departure.
What the $83 price really covers
At $83 per person, the price is reasonable if you want a full day on the water rather than a short harbor cruise. You receive guiding, full insurance, lunch, and roughly eight hours aboard the yacht. The value improves if you plan to use the snorkel equipment and stay for most of the stops.
The included lunch matters. Buying a substantial meal separately during a full-day boat trip can quickly push the cost higher, and the olive-oil-based dishes fit the setting better than having to return to town for food. The boat service also received strong praise, with specific appreciation for friendly, accommodating staff and a well-kept vessel.
The price does not cover drinks, so bring cash to buy what is available or confirm the arrangements before setting out. Outside food and drinks are not allowed. Hotel pickup and drop-off are also excluded, although the supplied information says a driver will take you back to your hotel when the yacht returns to Kas marina. That wording is not entirely clear, so check whether the return transfer applies to your booking.
Free cancellation is available up to 24 hours before the trip for a full refund, and you can reserve now and pay later. Those policies help if the weather or your schedule is uncertain, but they do not remove the need to check the final departure information the day before.
Who will enjoy this boat day most
I would choose this trip if you want a low-effort day with several chances to swim, a proper lunch, and enough free time to sit in the sun. It suits couples, friends, solo visitors, and anyone who would rather see the Kas coast from the water than spend another day moving between land attractions.
Solo visitors should find the format workable. The boat provides a social setting without requiring you to join a strenuous group activity, and the long stretches on deck make it easy to enjoy the day at your own pace. One solo booking also found the service particularly helpful, though no special solo program is listed.
Snorkelers will get the most from Twelve Isles, especially if the water is clear. Strong swimmers can add the cave visit and spend more time in the sea, while less active passengers can stay aboard. The tour is not suitable for people with mobility impairments, and that restriction should be taken seriously because boarding, moving around the yacht, and entering the water may be difficult.
Families may enjoy the swimming stops, but the available information does not give a minimum age, child pricing, or special family facilities. Ask before booking if you are traveling with young children. The same applies to dietary needs, since the meal is included but no menu or allergy information is provided.
Practical packing for eight hours at sea

Pack a towel, swimwear, and a camera. You will use all three. Add sun protection if you normally need it, though the supplied information only specifically lists the items above.
Keep cash with you because drinks are not included. Do not bring outside food or drinks, as these are not allowed. A small waterproof pouch for valuables would also be sensible, but the tour does not list storage arrangements, so keep your belongings to a minimum.
The boat may feel relaxing, but a full day under the sun can be tiring. Pace yourself at the first two stops instead of treating every swim as a challenge. You will enjoy the afternoon more if you leave some energy for Guvercin Island and the return route.
The final return to Kas marina
After the last stops at Harbour Mouth Bay and Big Pebble Beach, the yacht returns to Kas marina. The full outing takes about eight to nine hours, so expect to reach town in the late afternoon or early evening depending on the start and the pace of the day.
The return is deliberately unhurried. You get time to dry off, sit on deck, and watch the coast rather than being rushed straight back after the final swim. When the yacht arrives, the provided information says a driver will be available to take you back to your hotel. Confirm this detail in advance because hotel pickup is not included at the start.
Should you book this Kas boat tour?
Book it if your ideal Kas day means swimming in clear water, snorkeling around fish and a wreck, eating a relaxed boat lunch, and having several hours with no sightseeing pressure. The combination of Twelve Isles, the Guvercin Island shark monument, and the flexible deck time gives the day more variety than a simple swim cruise.
Think twice if you need guaranteed Kekova access, a fully exclusive yacht, hotel pickup, included drinks, or easy accessibility. Also confirm the precise route if the sunken city is important to you, since it is not part of the main schedule described here.
For most able-bodied visitors who want a full day at sea, the $83 cost is fair. Bring the right gear, arrive at the marina by 9:30am, and treat the day as a relaxed water outing rather than a tightly managed sightseeing program.
