The sea here isn't just something to look at — it's something to get into. Three ways to do it, from the deep blue up.
Milos is an island built around water, and most people only ever meet it from a sunbed or a boat deck. Get a little more active and the whole place changes. The volcanic coastline, the caves, the warm vents on the seabed — all of it rewards anyone willing to go a few metres further than the shallows.
There are three ways we'd point you toward, depending on how deep you want to go: scuba diving for the seabed itself, a kayak for the parts of the coast no road reaches, and snorkelling for the easy, mask-and-fins magic you can have on almost any afternoon. Here's how to do each one well.
Go deep
Scuba Diving
The seabed around Milos is unlike anywhere else in the Aegean. The island is volcanic, and that geology carries on underwater — warm vents, black-and-ochre rock, and the scattered cargo of ships that never made it home.
The Volcanic Underworld
Paleochori · hydrothermal vents
Off Paleochori, the volcano is still breathing. Hydrothermal vents on the seabed send streams of gas bubbles rising up through the blue, and in places the sand is warm — sometimes genuinely hot — to the touch. Diving over them feels otherworldly, like the water itself is alive.
It's a dive you won't find on many islands, and the single best reason to put a tank on your back here.
Caves, Walls & Ancient Cargo
All around the coast
Beyond the vents, Milos hides volcanic rock walls, swim-through caves, and amphora fields — scatterings of ancient cargo from shipwrecks thousands of years old, still resting where they fell. Visibility stays excellent through most of the season, and there's more marine life than the bare-looking coast lets on.
Several dive centres operate on the island, running everything from first-timer 'discover scuba' sessions in calm shallows to guided dives for the experienced. No experience? You can be breathing underwater by the afternoon.
Paddle the coast
Canoe & Kayak
A kayak is the slow, quiet way to reach the bits of coastline a boat tour rushes past and a car can't touch at all. No fixed schedule, no group of forty — just you, a paddle, and water clear enough to see your shadow on the seabed.
Firiplaka to Tsigrado
South coast · cliffs & sea caves
The stretch of south coast between Firiplaka and Tsigrado is made for paddling: dramatic cliff faces dropping straight into the sea, small caves to duck into, and water calm enough to make the whole thing a pleasure rather than a workout.
You set the pace, stop where you like, and slip into little coves that have no path down from above.
Paddle to Gerakas
South coast · no road in
Gerakas has no road — the only ways in are by boat or under your own steam — which is exactly why arriving by kayak feels like you've earned it. The beach is quiet, the water is glass-clear, and you'll likely have far more of it to yourself than anywhere you can drive to.
Rental outfits on the main beaches set you up with everything you need, including a quick lesson if it's your first time.
Mask, fins, go
Snorkelling
You don't need a boat, a licence, or any real skill to have one of the best swims of your trip — just a mask, a pair of fins, and a few of the right spots. Three stand out.
Sarakiniko
North coast · the lunar one
The white volcanic rock that makes Sarakiniko so famous above water carries on below it, into an underwater landscape of pale ridges, channels and ledges unlike anywhere else on the island. The water is usually calm and glassy, and the shallows near the rock are easy to explore with zero experience.
Kleftiko
Southwest · on a boat day
Save the best for a boat day. At Kleftiko you snorkel through sea caves, around towering limestone pillars, and over a healthy, varied seabed in some of the clearest water on the island. Most boat tours hand out masks and fins as standard, so all you have to do is jump in.
We've watched guests come back from every kind of day on this island, and the ones who really got in the water — past the shallows, into the blue — always have the best stories. If you're not sure where to start or what suits you, just ask when you arrive. Between the dive centres, the kayak rentals and a borrowed mask, there's a version of this for everyone.
