Marmaris bays & castle: Glass-bottom boat tour with lunch

Summary

Watching fish glide under your feet on Marmaris’ glass boat

Spend a day exploring Marmaris’ bays by glass-bottom boat with a local guide. Watch sea life glide beneath your feet, swim in clear water, visit a wish cave, and enjoy lunch on deck. You’ll leave with memories of sunlight on ancient stones and quiet moments above the sea.

What’s the experience like?

“If you make a wish in that cave, it might just come true,” our captain grinned as he steered us past Marmaris Castle. I was still trying to process the way the morning light bounced off the old stone walls — kind of golden, but also a little faded, like someone had washed the color out with saltwater. The boat itself felt different from any I’d been on before; you could see straight down through the glass lounge floor, and suddenly there were these flashes of silver darting below us. Kids pressed their noses to the glass and pointed out every fish — I probably looked just as excited.

We drifted between little islands and green coves for hours. At one stop, some people jumped in right away (the water was colder than I expected), while others just stretched out on sunbeds and let the breeze do its thing. Lunch came out simple but good — grilled chicken, salad, bread — nothing fancy but honestly that’s what hit the spot after swimming. There was this moment when we floated above an old shipwreck near Marmaris; you could see its shape through the blue haze below. Our guide told us stories about it, half-whispered so you had to lean in to catch them over the hum of the engine.

I tried making my wish at that cave — didn’t say it out loud because apparently that’s bad luck here. Li laughed at my attempt to pronounce its name in Turkish (I definitely butchered it). The air inside smelled damp and a bit earthy, which stuck with me more than I thought it would. On the way back, everyone seemed quieter — maybe tired or just full of sun and sea air. We got back to port around 4:30 pm but honestly I kept thinking about those underwater shapes long after we left.
