Marmaris Semi-Submarine and Glass-Bottom Boat: Is It Worth It?
ReactDown a narrow staircase in the hull of the boat, the noise of the deck fades and you find yourself in a long, cool room lined with windows below the waterline. Outside, the sea is blue-green and surprisingly clear; shoals of small fish swirl past the glass, rocks covered in sea urchins slide by and, on some routes, the shape of a sunken wreck comes into view.
That is the semi-submarine, sold in Marmaris as the “glass-bottom boat” or “underwater safari”. It is a popular family day out, but it is often misunderstood. This guide explains what it really is, how much time you actually spend looking underwater, what the 2026 tickets cost and who will enjoy it most.

Is it a real submarine?
No. A semi-submarine never dives. It is a boat that stays on the surface, with a passenger cabin built into the lower hull, below the waterline. Large windows let you look out at the seabed, fish and rocks while staying completely dry. There is no need to swim, dive or wear any equipment.
When you are not in the viewing room, you sit on the open deck like on any other excursion boat. In practice, the semi-submarine is a full-day boat trip with an underwater viewing session added.
How much time do you spend underwater?
This is the most important thing to know before booking. On the itineraries we checked, the underwater viewing takes about 20 minutes, for example while the boat circles over a sunken ship. The rest of the seven hours is spent cruising, swimming in the bays and having lunch.
What you see through the windows depends on the sea that day. On calm days with good visibility, you can see a lot; after wind, the water can be cloudier. Fish are wild, so no two trips are the same.
The route
A typical seven-hour route leaves Marmaris harbour around 09:30 and calls at four bays:
- Aquarium Bay: famous for its clear water; the best stop for snorkelling.
- Kadırga Bay: a swim stop beneath a rocky shoreline.
- Green Sea Bay: a quieter break for swimming.
- Paradise Island (Cennet Adası) Bay: the last stop before returning to Marmaris in the late afternoon.
The exact order and stops depend on the operator and the weather.
2026 prices
| Ticket type | 2026 price | Approx. USD | Approx. TL | Includes |
|---|---|---|---|---|
| Harbour ticket, adult | €29 | ~$32 | ~1,630 TL | Boat trip, lunch; meet at the harbour near the Atatürk statue |
| Harbour ticket, child | €14 | ~$16 | ~785 TL | As above |
| Packaged tour | From €66 | ~$74 | ~3,700 TL | Boat trip, lunch, hotel pickup and return, English-speaking guide |
The difference is mostly the transfer and the guide. If you are staying in central Marmaris and can walk to the harbour, the cheaper ticket is clearly the better value. From İçmeler, Turunç or further out, a package with hotel transfer saves you the hassle. On our site, you can book the glass-bottom semi-submarine day trip.
Drinks are not included on most tickets and are sold on board; outside food and drinks are usually not allowed. Snorkelling equipment can sometimes be rented for a small extra charge.
The 2026 season ended in late October. Expect new prices to be published in spring 2027.
Is it worth it?
Yes, if you want an easy, relaxed day at sea and the underwater view is a bonus rather than the main event. Children in particular love the viewing room, and the swim stops and lunch make it a full day out for a fair price.
Probably not, if you are expecting hours of submarine sightseeing. If the underwater world is what really interests you, an introductory scuba dive or simply snorkelling in Aquarium Bay will show you far more. If you mainly want swimming and scenery, a regular Marmaris boat trip does the same for a similar or lower price.
Who is it best for?
- Families with young children: the viewing room is exciting, safe and dry, and there are plenty of breaks.
- Non-swimmers: you can see the underwater world without getting into the water; the swim stops are optional.
- Grandparents and mixed-age groups: a gentle, low-effort day out.
- Snorkellers: the bay stops are good for snorkelling; bring your own mask or ask about rentals.
- Visitors with limited mobility: the viewing room is reached by a staircase. Ask the operator about the exact boat, the steps and the toilets before booking.
What to bring
- Swimwear, a towel and a change of clothes
- Sunscreen, a hat and sunglasses
- Your own snorkel and mask, if you have them
- Cash or a card for drinks on board
- Seasickness tablets if you are prone to it; take them before the boat leaves
Keep phones and cameras secure on the stairs to the viewing room, and follow the crew’s instructions when entering and leaving it.
