On the water | Sifnos
Milos & the Kleftiko sea caves
Eight hours west to Milos for the white cliffs and caves of Kleftiko, and a sand slope you slide down into the sea.
Milos is the big day. Bigger than Sifnos and stranger, volcanic, streaked with minerals, and the west coast is a Natura 2000 area of white cliffs and sea caves. The boat rounds the Kleftiko stacks and stays about an hour and a quarter. If the sea allows, you get the sand slope you slide down into the water. Eight hours out of Platis Gialos, from €1,700 for the boat in 2026, snorkelling gear on board.
The route
- 01Early out from Platis Gialos
- 02West across to Milos
- 03Kleftiko sea caves and white cliffs
- 04Swim stops and the sand slope, then back
What you'll see
The Kleftiko caves and limestone stacks, the Sykia cave and Sarakiniko, the mineral-coloured west coast, and swimming spots you only reach by boat.
Who it suits
Confident swimmers, and anyone who wants the big day out. The crossing is long, so not one for very young children.
Good to know
How long is the Milos trip?
Eight hours. Ask A La Mer to confirm the timing and the route when you book. The sea decides how much of it is possible.
What is Kleftiko?
A cluster of white limestone stacks and caves on the southwest coast of Milos. No road reaches it. There is a rough path down from the end of a dirt track, but the caves and arches you can only enter from the water.
