From Marmaris: Day Trip by Glass Bottom Semi Submarine

The most unusual part of this Marmaris boat trip is the underwater viewing room. You can watch fish gather around the glass, inspect submerged plants, and see a sunken boat without getting wet. Above the water, the route passes sea caves, rocky coves, and clear turquoise bays.

I like the choice of four swimming stops, since you get more than a quick jump overboard, and I like the boat itself: spacious decks, shaded seating, air conditioning, clean toilets, and plenty of sunbeds. The main drawback is access to the water. You usually enter from a ladder into deep water, so this is not ideal if you cannot climb or feel uneasy swimming away from shore.

Key points at a glance

• Watch a sunken boat and fish through glass windows in the lower viewing room.
• Swim at four bays: Aquarium Bay, Kadirga Bay, Green Sea Bay, and Paradise Island Bay.
• Choose your spot on three levels: an air-conditioned interior, a shaded sunbed deck, or an open upper deck.
• Eat lunch on board with options such as chicken, meatballs, schnitzel, or nuggets, served with rice and salad.
• Use life jackets and sturdy ladders if deep water or swimming confidence is a concern.
• Bring a towel, sunscreen, swimwear, sunglasses, and cash or a card for drinks, ice cream, and extras.

Why this glass-bottom cruise is different

Marmaris has no shortage of boat outings, but this one gives you two kinds of sea time. You can stay dry and watch the water below, then change into swimwear and enter the same clear sea from the back of the boat.

The lower viewing room is the trip’s special feature. It is not a full submarine ride, and you should not expect a long technical tour beneath the surface. Instead, the boat pauses near underwater sights, including a sunken boat, while fish gather near the glass. Staff may feed the fish, making them easier to see.

This works well for families. Young children can watch the underwater scene without having to snorkel, and older passengers can enjoy the views from inside while others swim. The viewing room and other indoor spaces are air-conditioned, which matters on a long, hot day at sea.

You also get a good choice of places to sit. The lower indoor area includes the dining room and viewing room. The next level has sunbeds with shade, while the top deck is open to full sun. Arrive early if you want a particular place, especially if your group wants several sunbeds together.

Meeting near the Ataturk statue

The meeting point is in central Marmaris, close to the Ataturk statue and about 100 meters farther along the road toward the marina. If you take a taxi, tell the driver it is opposite the district governor’s office.

That location is useful because you do not need to find a distant marina or arrange a complicated transfer. The supplied information gives a central meeting point rather than a standard hotel pickup. Older bookings sometimes included hotel pickup, but you should rely on the meeting instructions attached to your own reservation.

The cruise lasts most of the day, with about seven hours on the water. Starting times vary, so check the available departure when booking. This is a full outing, not a short harbor ride, and you should leave your afternoon open.

The underwater room and the sunken boat

The first major attraction is often the underwater viewing area. You go below deck into an air-conditioned room and look through the glass panels at fish, plants, and the sea floor.

One of the most interesting sights is a sunken boat. It gives the glass-bottom section a clear purpose, especially for children, who may lose interest if they only see open water and small fish. The crew can also feed fish near the windows, improving the view.

Visibility depends on the sea and the light. Even in clear water, this is not an aquarium with guaranteed close-up views every second. You may spend a little time waiting for fish to appear, and the area can become popular when several people head downstairs at once.

I would treat the underwater room as a worthwhile extra rather than the entire reason to book. The best value comes from combining it with the four swim stops and the long, comfortable ride through the bays.

Aquarium Bay: your first swim in clear water

Aquarium Bay is one of the named swimming stops. The water is clear, and the bay gives you an early chance to get into the sea and settle into the rhythm of the day.

The boat stops offshore, so you normally enter the water from the vessel rather than walk onto a beach. That detail matters. You need to be comfortable using a ladder and swimming in water that may be deeper than you expect.

If you are not a confident swimmer, ask for a life jacket. Adult and child life jackets are available, and you can still enjoy the stop while floating near the boat. The crew also uses ladders designed to make getting back aboard easier, including for older passengers.

The first jump can feel cool, even in warm weather. Once you are in, the clear water and time to swim make this more than a token stop. Bring water shoes if your feet are sensitive, since rocky surfaces may occur around some swimming areas.

Kadirga Bay and Green Sea Bay

Kadirga Bay and Green Sea Bay continue the swimming part of the trip. Each stop gives you another chance to swim, float, or simply watch the scenery from the deck if you prefer to stay dry.

The exact order and time at each bay can vary. One useful improvement would be a clear timetable or announcements showing the name of each bay and how long remains before departure. You may want to ask the crew directly when the next stop ends, especially if you are swimming with children.

Bring a snorkel if you want to look for fish and underwater features yourself. Snorkels may be available for purchase on board, but packing your own is simpler. Water shoes are also useful if you plan to explore rocky edges rather than stay beside the boat.

These stops are a good reason not to spend the entire morning claiming the best sunbed. The trip works best when you alternate between the water, the underwater room, lunch, and the deck. If you only want to sunbathe, you can do that, but you will miss much of what makes this outing different from a normal scenic cruise.

Paradise Island Bay and the final swim

Paradise Island Bay is the fourth named swimming stop. By this stage, the day has a relaxed pace: swim, climb back aboard, dry off, eat, and watch the coast pass by.

The bays are valued for their clear water and sheltered feel, but do not confuse the stop names with guaranteed beach time. The boat may stop in open water near a bay, and your access is by ladder. One passenger with limited mobility was happy staying aboard, but could not get off at the swimming areas because of the ladder and deep water.

That makes the upper deck important. You can enjoy the scenery, take photographs, and watch swimmers without feeling that you must enter the sea. Sunbeds are plentiful, with full sun and shaded areas available. The boat also provides a practical fallback if the water is cooler than expected or you have had enough swimming.

Some lucky departures have seen dolphins close to the boat, and turtles have been spotted while snorkeling. These are wildlife sightings, not a promise, so enjoy them if they happen rather than booking with that expectation.

Lunch with a choice of main dishes

Lunch is included in the $34 price. The basic meal comes with a main dish, rice, salad, and sauces, and the onboard choices may include chicken fillet, meatballs, schnitzel, or chicken nuggets. The children’s option is useful for families, while adults can choose a more substantial chicken or meatball dish.

Food is served in an air-conditioned dining area, described as a fast-food hall. That may sound plain, but it is practical on a hot boat. You can eat out of the sun, cool down, and use the indoor facilities before returning to the deck.

The food has generally been well received, with generous portions and good timing. Still, expectations should stay sensible. This is an included boat lunch, not a restaurant meal, and one past passenger found the food was not hot enough. If temperature matters to you, eat soon after your dish is served.

Vegetarian provision appears limited. Rice and salad may be available, but there is no clearly listed vegetarian main dish. If you do not eat meat, ask before booking or confirm with the operator. A grilled cheese option would make the meal more useful for vegetarian passengers, but it is not listed as included.

Drinks, ice cream, and other snacks cost extra. Prices aboard have been described as reasonable, but bring money if you want refreshments throughout the day. Sunscreen and some small essentials may also be sold on board, though you should not depend on that.

Three decks, air conditioning, and clean facilities

A long boat day can become tiring if the vessel is cramped or lacks shade. This boat has several seating zones, which spreads people out and lets you choose how much sun you want.

The indoor spaces include the restaurant, toilets, changing cabins, corridors, and the underwater viewing room. They are air-conditioned. The middle deck offers shaded sunbeds, and the upper deck is open to direct sunlight.

The boat has changing facilities and toilets, which makes four swimming stops much easier. You can change out of wet swimwear, eat in comfort, and use the facilities without waiting until you return to Marmaris.

The vessel is wheelchair accessible, but the swimming stops are a separate matter. Accessibility aboard the boat does not remove the need to climb a ladder into and out of the sea. If you use a wheelchair or have limited mobility, confirm exactly what assistance is available before booking and plan to enjoy the indoor and deck areas if swimming access is difficult.

Smoking restrictions also matter to some families. The dining area is non-smoking, giving you a cooler and more comfortable place to eat away from the open deck.

Is $34 good value?

At $34 per person, the trip offers a strong package for a full day. You get the boat ride, underwater viewing, four named swimming stops, lunch, sunbed use, changing rooms, toilets, and air-conditioned indoor space.

The value improves if you would otherwise pay separately for a short cruise and a meal. It is also useful for mixed groups. Strong swimmers can spend much of the day in the water, children can watch fish and the wreck, and non-swimmers can sit in the shade or air conditioning.

Extra costs are limited to drinks, ice cream, towels, and optional purchases such as snorkels. Towels are not included, so bring your own. The price does not cover personal spending on board.

The main tradeoff is time. Seven hours is generous if you want a slow day, but it may feel long if you are ready to leave after two or three swims. One passenger felt the day could have ended sooner. I would book it when you want a full day at sea, not when you are looking for a quick activity between other plans.

Who should book this day trip?

I would recommend it to families, couples, groups of friends, and older passengers who want a gentle sea outing with plenty of seating. The air conditioning, clean facilities, life jackets, and ladders make it more approachable than a small, basic boat.

It suits you especially well if you want to combine swimming and sightseeing. You do not need to be a strong swimmer to take part, although you do need to manage the ladder if you enter the water. The underwater room gives non-swimmers a real activity rather than leaving them to watch from a chair.

It is less suitable if you need a quiet, small-group sailing trip, a serious snorkeling expedition, or a sandy beach at every stop. The boat is large, and the route is built around comfort, shared facilities, and several swimming breaks rather than solitude.

Book early in the day if sunbed position matters. Choose shade if you burn easily, and bring sunscreen for reapplication after every swim. Use the life jacket if you feel uncertain, and ask the crew how long remains at each bay.

The booking details that matter

You can cancel up to 24 hours before departure for a full refund, and the reserve-now, pay-later option keeps your plans flexible. The activity is valid for one day, with departure times based on availability.

An English and Russian audio guide is included. The information does not provide a named guide or captain, so do not expect to book a particular staff member. The crew handles the boat, swimming access, food service, and safety arrangements.

Bring:

• Swimwear and a towel
• Sunscreen and sunglasses
• Water shoes if your feet are sensitive
• A snorkel if you want to look beneath the surface during swim stops
• Money for drinks, ice cream, or snacks

Should you book it?

Yes, if you want a good-value, full-day boat outing with real variety. The combination of an underwater viewing room, a sunken boat, four swimming stops, lunch, sunbeds, and air-conditioned areas gives you plenty to do for the price.

Think twice if you dislike long group excursions or cannot climb a boat ladder. For everyone else, this is a comfortable way to see Marmaris from the water while staying dry when you want and swimming when you choose.
