What’s the experience like?

The first thing that caught me off guard was how quiet it got as we left Milos bay behind — just the slap of water against the hull and someone’s laugh drifting back from the bow. Our skipper, Nikos, pointed out these tiny fishing houses painted every color you can imagine (he called them “Sirmata” — I probably said it wrong). The air smelled a bit salty and almost sweet near Klima. I tried to take a photo but honestly, it didn’t do it justice. There’s something about seeing those colors in the morning light that just sticks with you.

We sailed past this rock called Arkoudes — it’s shaped like a bear if you squint (or maybe if you’ve had one of the cold beers they hand out). Then we stopped at Kalogries bay for our first swim. The water was so clear I could see my toes dangling under me. I hesitated before jumping in because it looked almost fake, but wow — cold at first, then perfect. Our guide Maria swam alongside us and pointed out little fish darting around. She told us stories about pirates hiding out in these coves centuries ago. I don’t know if she was making some of it up but it made me grin.

Kleftiko was next and honestly, nothing prepares you for those white cliffs and caves. We snorkeled through arches while Maria led the way — she kept finding new tunnels for us to try. At one point I just floated on my back watching sunlight flicker underwater. Lunch was cooked right there on deck (grilled veggies, fresh bread, something with lemon that tasted like summer) and everyone ate with wet hair and sandy feet. It felt like nobody wanted to leave that spot.

Later we drifted past Gerakas beach where steam curled up from hot springs — the smell reminded me of boiled eggs for a second (not bad, just funny). The last swim was at Galazia Nera in Poliegos. If blue has a hundred shades, they’re all here. I still think about floating there with nothing but sky above me and rock below; time sort of paused for a while.
