Kastanas Beach sits on the coast of Milos in the South Aegean and is reached by local road followed by a short walk over uneven natural ground. Access appears open, with no gate, set hours, or entry fee indicated, so daylight visits are the normal pattern. Parking is limited and informal near the access point, and mornings usually offer the easiest arrival. No direct public transport is indicated, so most people arrive by car, scooter, or on foot from nearby accommodation. The shore is undeveloped, without sunbeds, toilets, showers, food outlets, or lifeguard cover. The surface is sand mixed with pebbles and rock, and the seabed continues that mixed character. Footwear for sharp or uneven sections is sensible, along with a sun umbrella, drinking water, food, and a bag for rubbish. The cove water is generally sheltered, calm in settled weather, and clear, suiting relaxed swimming and floating. Midday brings strong sun with little shade, so a short or half-day stay works best. June to September generally gives the warmest and driest conditions. Children need close supervision because the site is unsupervised, uneven, and without facilities. Dogs have no stated policy, so close control is important on a small shared shore. Before leaving, check wind and sea state, as open-shore conditions can change during the day. Allow extra time for the uneven walk, keep to firm footing, and give other visitors space on the small shore. Since no bins or cleaning services are indicated, carry everything out and leave rocks and plants undisturbed.
