This isolation is its charm: it rarely sees crowds, and on most days visitors have the cove almost to themselves, providing a serene setting for relaxation.

Its volcanic colours, clear water and complete lack of development make it feel wild and unspoiled, a striking contrast to the busier headline beaches.

Where is Kastanas beach and how do you get there?
Kastanas beach lies on the northeastern coast of Milos, a remote spot about a 25-minute drive from Adamas. Access is difficult, best reached by quad or 4×4 along a steep dirt road, or by boat.
Kastanas sits in the northeast. The remote coast holds it. It lies about 25 minutes from Adamas. The isolation defines it.
The access is difficult. A steep dirt road leads in. A quad or 4×4 handles it best. A normal car struggles.
A boat is the easy route. A cruise reaches the cove from the sea. The boat avoids the rough road. The water frames the arrival.
The hard access keeps it quiet. Few make the effort to reach it. Compare wheels in our Milos ATV rental guide. The next section covers what it is like.
Reaching Kastanas is part of its character, as the difficult access is exactly what keeps it so quiet. The beach sits in a remote corner of the northeast, about a 25-minute drive from the port of Adamas, but the final approach is the challenge. It is reached either by a steep, rough dirt road that is hard to navigate, or by boat from the sea. The best way to drive there is by a quad or a 4×4, which handle the loose, steep track far better than an ordinary hire car.
For travellers without a suitable vehicle, a boat is the easier option, whether on a tour that stops there or by a private hire. Arriving from the water also frames the cove and its colourful rocks beautifully. Whichever way you come, it is essential to arrive prepared, as there are no facilities, no shade and no shop, so plenty of water, sun protection and supplies are a must. A pair of water shoes also helps on the rocky seabed and pebbly shore.
Reaching Kastanas is the price of its peace. The cove lies in a remote corner of the northeast, about a 25-minute drive from Adamas, but the final approach is a steep, rough dirt track best tackled by a quad or 4×4 rather than an ordinary hire car. The alternative is to arrive by boat, which also frames the colourful rocks beautifully from the water. Either way, the difficult access is exactly what keeps the beach so quiet, deterring the crowds and leaving the cove to the handful of visitors prepared to make the effort to find it.

Kastanas is a beach for those who love wild, natural scenery over comfort. The shore is coarse sand mixed with multicoloured pebbles, washed by clear, emerald-green water, and the whole cove is framed by dramatic volcanic rock in shades of red, orange and purple. The colours, both above and below the water, are the highlight, glowing in the bright sun. The rocky seabed makes water shoes a sensible idea for getting in and out comfortably.
The trade-off for this beauty is a complete lack of development. There are no sunbeds, no beach bar, no taverna and no shade, so visitors must bring everything they need: plenty of water, sun protection, snacks and an umbrella for shade. This bareness is part of the appeal, keeping the cove pristine and uncrowded. For self-sufficient travellers who come prepared, Kastanas offers a rare, untouched beach experience with colour and clarity hard to match elsewhere on the island.
