The Experience

The boat leaves the port in the morning and the first thing you notice is Marmaris Castle rising above the waterline. From there the route moves through the bays and islands that ring the coast, and the glass lounge lets you watch the underwater world without getting wet—fish, rock formations and the seabed pass below while you stay dry and comfortable inside. The boat makes stops for swimming in the clearest water, so you can jump in or stay on deck with a sunbed if you prefer to sunbathe instead.

Two moments break up the day. One is the wish cave, a sea cave you drift into and can make a wish before the boat backs out. The other is a sunken ship near Marmaris that sits on the bottom where the glass lounge gives you a clear view of it—you can photograph it from inside without suiting up. Lunch is served on board and included in the price, and the boat's reputation rests on cleanliness and a family atmosphere, so the galley and deck stay well-kept through the day.

The entire route takes 7 hours from departure to return, and you're back at the port by 4:30 pm. An audio guide in English runs throughout, and pickup from your hotel is included—the boat handles the logistics so you only show up and board. Full passenger insurance covers everyone on the manifest.
