Agios Dimitrios is a marvelous triangular peebly beach with transparent turquoise waters. One of the prettiest in Alonissos, is located in its northeastern coast, opposite the island of Peristera and can be reached over a dirt track. An attractive beach bar has been built, mainly out of driftwood. It is usually open only in the high season (July and August). There are sunbeds for hire on the south side but watch out for sea urchins. The north side of the beach is quieter but can suffer from some rubbish. Road access has been much improved recently, which makes the beach more popular. It is situated at a 14 kilometers distance of Patitiri (port). The beach is named after a monastery which has now been completely destroyed. Only its remains can be seen next to the main road.
