Kastanas Beach is a hidden gem tucked away on the northeast coast of Milos. This remote paradise features a shoreline of colorful volcanic pebbles and breathtaking transparent waters. Its seclusion and challenging dirt road access leave it relatively deserted, making it the ideal spot for those seeking solitude, relaxation, and a true island escape.
What to Do 
- Soak up the scenery – Take in the one-of-a-kind volcanic rock formations and the beach’s signature multi-colored pebbles.
- Go for a dip – Wade into the beach’s calm, clear waters that are perfect for swimming and snorkeling.
- Sunbathe in peace – Lay out on the open beach free of crowds. The southern section tends to attract more visitors while the northern end stays quieter.
- Take the path less traveled – Getting to Kastanas Beach is an adventure in itself. Be prepared to traverse rough, unpaved roads – a quad bike is highly recommended.
- Pack provisions – Make sure to stock up on food, water, and supplies before arriving as there are no amenities available at the beach itself.
