It seems like Kastanas Beach was never meant to be found by accident. It's hidden away on the quieter eastern side of Milos, behind rough dirt roads, sharp turns and a landscape that gets more rugged the further you go. Kastanas is not like most sandy beaches. You can't lie down on a queue of sunbeds or get a cold drink from a beach bar here. Instead, it's something much more interesting: a beach made entirely of colourful pebbles. Real, natural mosaics of pink, red, purple, grey, white and everything in between. The stones are smooth, round and shiny in the sun, like someone polished them overnight. The colours at Kastanas are magical. It feels like nature's version of confetti because it's soft and warm at the same time.
How Kastanas Really Feels
The truth is that Kastanas seems like a secret. You might only see a few people here, even in the middle of summer. When you first step onto the beach, it feels different than when you walk on sand. The pebbles move gently under your feet, making a soft sound. The beach goes down to the water and the sea is very clear right away. Even when you're up to your waist in water, you can see the stones below. The colours around you, like the reddish cliffs above and the pebble beach below, make the place feel almost like a dream. It's nice to sit down, let the stones warm up in the sun and listen to the waves gently rolling over them. It feels like an older, quieter version of Milos, one that hasn't been affected by tourism.
The Water at Kastanas
Swimming at Kastanas is a little different from swimming at sandy beaches because the seabed is made of pebbles. The water is so clear that it looks like glass. This is a great place to explore if you like snorkelling because the rocks and underwater formations make interesting textures and light patterns. The water gets deeper a little faster than in sandy bays, which is great if you like to dive in and swim right away. You forget about the heat of the road and the sun as soon as the cool water wraps around you. The pebbles change the colour of the water in beautiful ways. Where the stones are light, the water is turquoise and where the water drops off, it is deep blue. Every time you move, you make a sparkle under you. It makes you feel calm, refreshed and a little bit sleepy. The beach is crazy and totally out of order. Kastanas doesn't have any services, like umbrellas, sunbeds, food, drinks, or anything else. There are no buildings, no kiosks and no trees that provide shade.
To make your visit comfortable, you'll need to get ready:
Bring a lot of water
Pack some snacks
Bring an umbrella to stay out of the sun.
If you want to walk on pebbles more easily, bring sandals or water shoes.
If you like to explore underwater, bring snorkelling gear.
This is a place for people who like nature as it is: raw, quiet and not planned. This beach isn't the kind where you can spend the whole day doing nothing. It's more like, "Let me go to a quiet place, slow down for a few hours and enjoy nature without being bothered."
How to Get to Kastanas Beach
By Land
You will drive on a mix of paved and dirt roads. As you get closer, the dirt part gets bumpier. It's not dangerous, but the bumps are big enough that you'll want to take it easy. A quad or a car with more ground clearance is definitely more comfortable. You walk a short way down to the beach from the small clearing where people park. The walk isn't too long or hard, but you'll never forget the moment you see the beach. When you see the red cliffs, the colourful stones and the shimmering sea all at once, you know you've arrived somewhere special.
By Boat
Some private boat trips around the island go by Kastanas or stop nearby for a swim, but it's not the most common place to stop. The view from the water is amazing if you can get there by boat. The cliffs' colours look even more vibrant and the beach looks like a rainbow-colored stripe between the rocks and the sea.
