From Marmaris: Day Trip by Glass Bottom Semi Submarine

Look beneath Marmaris without getting wet. This full-day glass-bottom cruise combines easy underwater viewing with four long swimming stops along the eastern Mediterranean coast. I like the clear views of fish, plants, sea caves, canyons, and a sunken boat, and I like the roomy boat with air-conditioned indoor areas, shaded seating, and plenty of sunbeds. The main drawback is that swimming means entering deep water and climbing a ladder back aboard, so it is not equally convenient for everyone.

The included lunch is another strong point, with meatballs, chicken, schnitzel, or nuggets served with rice, salad, sauce, and mashed potatoes. Drinks, ice cream, towels, and snorkel gear cost extra, and the day can feel long if you prefer a quick boat outing rather than hours at sea.

Key points before you book

• Four named bays: Swim at Aquarium Bay, Kadirga Bay, Green Sea Bay, and Paradise Island Bay, with clear water and time to enjoy each stop.
• A real underwater viewing room: The lower deck lets you see fish, plants, and a sunken boat through glass windows while staying dry.
• A comfortable three-level boat: Choose air-conditioned indoor seating, shaded sunbeds, or an open upper deck in full sun.
• Lunch is included: Pick from several meat and chicken dishes, served with rice, salad, sauce, and mashed potatoes.
• Good for mixed-age groups: Life jackets, changing cabins, clean toilets, and useful ladders make the boat friendly for families and less confident swimmers.
• Bring extra swimming gear: Pack a towel, snorkel, water shoes, sunscreen, and cash or a card for drinks and ice cream.

What this Marmaris cruise is really like

This is a relaxed day at sea rather than a fast sightseeing trip. You spend time moving along the coast, looking through the underwater windows, swimming from the boat, eating lunch, and finding a comfortable place to sit.

The vessel has enough room to spread out, with an air-conditioned restaurant and indoor areas, shaded seating on the middle level, and open sunbeds above. That choice matters in Marmaris. You can begin in the sun, retreat to shade, and cool down indoors without ending the day.

The cruise lasts about seven hours, according to the strongest practical feedback, and the schedule is built around several swim breaks. You will not simply sail past the bays for a quick photograph. The swimming stops are a major part of the day, so bring swimwear even if you mainly want to watch from the deck.

The atmosphere is family-friendly and unhurried. The crew provides life jackets for adults and children, and the ladders into the water are described as manageable for older people. Still, you need enough mobility to climb back onto the boat. The swimming areas are in deep water, not shallow sandy beaches, so that distinction is important.

Finding the boat near Ataturk statue

The meeting point is central and fairly easy to reach. It is close to the Ataturk statue, 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.

Arrive early if you want the best choice of sunbed. The boat has many places to sit, including shaded and sunny areas, but adjacent loungers can go quickly. This is especially useful for families or couples who want to sit together.

The booking terms are practical. You can cancel up to 24 hours before departure for a full refund, and you can reserve now while paying later. The activity is listed as wheelchair accessible, though the swimming section itself requires getting into deep water and using a ladder. If you use a wheelchair, confirm exactly which parts of the boat and transfer areas suit your needs before booking.

English and Russian audio guidance is included. Do not expect a detailed coastal lecture throughout the day, though. The experience is mainly about the sea, swimming, and relaxation, and information about each bay may be limited.

The glass-bottom viewing room and sunken boat

The underwater section gives this cruise its reason for being. You can go below deck and look through the glass windows at fish and plants without getting into the water. It is closer to sitting inside a floating aquarium than taking a true submarine ride, but the effect is enjoyable, especially for children.

One of the early viewing moments focuses on a sunken boat. Fish gather around the wreck, and the crew may feed them near the viewing area, making them easier to see through the glass. This is a particularly good feature for anyone who does not swim, and it gives children something to watch before the first swimming stop.

The windows are most useful when the water is clear and the boat is positioned well. You should keep expectations sensible. This is not a scientific marine tour, and the underwater room is only one part of a much larger day. You may spend more time on the upper deck or in the bays than below the waterline.

The lower deck, restaurant, changing cabins, toilets, corridors, and underwater viewing room are air-conditioned. That is a welcome detail after sitting in the sun or returning from a swim.

Aquarium Bay: an easy first taste of the water

Aquarium Bay is one of the four named swimming stops. The turquoise water and clear underwater views make it a natural introduction to the day.

The first jump can feel cold, especially early in the season, but you soon adjust. Life jackets are available if you are not a strong swimmer or simply want extra support. You can also remain on deck, use a sunbed, and watch the activity without taking part.

Bring water shoes if your feet are sensitive. Some parts of the swimming areas can be rocky, and the boat does not place you directly onto a soft beach. A snorkel is useful too, since the glass windows show the underwater world, but snorkeling lets you inspect the rocks and fish at your own pace.

Kadirga Bay and Green Sea Bay

Kadirga Bay and Green Sea Bay continue the same pattern: a scenic setting, a swimming break, and time to enjoy the water rather than rush through it. The coast around Marmaris is known for steep coves, sea caves, and bright water, and the boat gives you a different view from the usual land-based beach day.

The appeal here is variety in a simple form. You can swim at one stop, sunbathe at the next, and spend another pause looking through the lower-deck windows. If one bay feels too busy or the water is not your preferred temperature, another stop follows.

The schedule is not always clearly announced. It would help to know the name of each bay and the remaining swimming time, so keep an eye on the crew and listen for instructions. You may want to ask about the next departure from the boat or the length of the stop.

There is enough room to avoid feeling packed in, but the boat can still become busy during popular summer departures. Arriving early improves your choice of seat. Once underway, most people settle into their preferred spot and move around between the swimming, dining, and viewing areas.

Paradise Island Bay and the final swim

Paradise Island Bay is the fourth named swimming stop and a fitting place to spend more time in the water. The appeal is not a list of monuments or a guided walking route. It is the combination of clear sea, rocky coves, and time to swim without having to organize transport between several beaches.

You enter the water from the boat, then climb back up the ladder when the crew signals that it is time to leave. Life jackets make the water easier for children and less confident swimmers, but they do not remove the need to use the ladder.

This arrangement works well for active families, couples, and anyone who likes a full day of sea time. It is less suitable if you need a shallow entry, a sandy beach, or frequent access to land. A friend or family member who cannot manage the ladder can still enjoy the decks and underwater room, but may miss the main swimming feature.

Some departures have been described as including an additional viewing or swim pause, but the clearly named program centers on four bays. Check the exact schedule on your departure day if the number of stops matters to you.

Lunch in the air-conditioned dining area

Lunch is included in the $34 price, which makes the cruise better value than a boat outing where you must buy a full meal separately. You eat in an air-conditioned fast-food-style hall, a sensible escape from the midday heat.

The main choices include meatballs, chicken fillet, schnitzel, and chicken nuggets. Meals come with rice, salad, sauce, and mashed potatoes. Several people found the portions satisfying, and the choice of chicken nuggets can help with children who are not keen on unfamiliar food.

The food is basic rather than gourmet, but that is appropriate for a boat day. You get a proper plate, not just a packet of snacks, and the timing generally fits the middle of the cruise. Drinks, ice cream, and extra snacks are sold separately, with prices described as reasonable by several people.

Vegetarian choice is the weak spot. Salad and rice may be available, but there is no clearly stated vegetarian main course. If you do not eat meat, ask the operator what can be provided before booking rather than relying on the included menu.

Food temperature has not always been perfect. One serious complaint described lunch arriving less than hot, so if your meal seems lukewarm, speak to the staff promptly. Most feedback about the meal is positive, but this is the one area where expectations should stay practical.

Sunbeds, shade, and the boat’s best spaces

The boat’s layout is one of its strongest features. The upper deck has open sunbeds for full sun, while another level provides shade. The indoor areas are air-conditioned and include the restaurant, toilets, changing cabins, corridors, and the underwater room.

I would choose a shaded place first, then move into the sun when the boat is underway or during a swim stop. Full-day exposure adds up quickly, even when a breeze makes the heat feel mild. Reapply sunscreen after every swim, wear sunglasses, and keep a cover-up nearby.

The boat is reported to be clean, with tidy toilets and useful changing facilities. That matters on a seven-hour outing. You are not forced to remain in wet swimwear or search for a beach restroom after each stop.

Smoking and non-smoking preferences may matter to your group. The lunch area has been described as non-smoking, while the outdoor decks may suit people who want more open air. Ask the crew if you need a specific seating arrangement.

Dolphins have occasionally been seen close to the boat, and turtles have been spotted while snorkeling. These are lucky sightings, not promised parts of the program, but they show the kind of wildlife you might encounter in the coves.

What to pack, and what costs extra

Pack light, but pack the right things:

• Swimwear and a towel
• Sunscreen and sunglasses
• Water shoes for rocky areas
• A snorkel if you want to inspect fish and reefs
• A dry bag or secure bag for small valuables
• Money for drinks, ice cream, snacks, or equipment bought onboard

Towels are not included. Drinks are also extra, and you should not assume that food and beverages from home are permitted onboard. Snorkels may be available for purchase, but bringing your own is simpler if you already have one.

The boat may sell practical items such as sunscreen and swimming gear. That is convenient, but onboard prices and availability can change. Bring what you know you will need rather than counting on the sales counter.

Is $34 good value?

At $34 per person, the price covers a full day on the water, the glass-bottom viewing experience, four named swimming stops, use of the sunbed areas, and lunch. That is strong value if you plan to swim and spend several hours using the boat.

The value is weaker if you dislike swimming from a boat or want a short sightseeing cruise. Much of the day is built around pauses in the bays, so non-swimmers may spend more time sunbathing and watching others enjoy the water.

You also need to budget for drinks, ice cream, towels if you forget one, and possible snorkel equipment. These extras are not hidden parts of the package, but they can raise the final cost for a family.

The clean boat, air conditioning, changing areas, and lunch help justify the fare. You are paying for comfort as well as transport. Compared with a basic boat ride with limited seating and no proper meal, this is a sensible choice for a relaxed full-day outing.

Who should book this boat trip?

I would recommend it to families, couples, older people who can use a ladder, and anyone who wants a gentle introduction to the coast. Children get the underwater windows and fish, swimmers get four sea stops, and sun worshippers get several deck options.

It also suits mixed groups. A strong swimmer can spend the day in the water while a less confident companion uses a life jacket, watches from the deck, or visits the underwater room.

I would think twice if you need a sandy beach, shallow water, a vegetarian lunch, or a tightly guided sightseeing program. The trip is more about comfort and free time than coastal facts. You should also avoid it if climbing a boat ladder is difficult.

The easiest way to improve the day is to arrive early, claim a shaded or sunny place that suits you, bring a snorkel and water shoes, and ask about the stop schedule. With those small preparations, the cruise gives you a lot of sea time for the money.
