Megali Ammos is considered the Skiathos Town beach as it lies just 3 kilometres away over the headland from the town harbour, so it's walkable or just a quick taxi or bus ride away.
Megali Ammos and neighbouring Vassilias form a two-kilometre long strip of good sand, with Megali Ammos the busier and most developed of the two, it being the nearest to Skiathos Town.
Megali Ammos means "big sands" in Greek but, although long and sandy, the beach is still quite narrow, with two to three rows of tightly packed sunbeds from one end to the other in the high season.
Hotels and tavernas line the back of Megali Ammos beach and behind those is the main road where bus stop numbers 5 and 6 services this end of the beach with just a few minutes walk to the sands.
Beyond the road, the land slopes steeply into the hills so, if you are based in Megali Ammos, it is a good idea to check if your accommodation is below the main road; above the main road and you face a steep walk uphill after a day on the beach.
Megali Ammos beach is well organised with plenty of sunbeds and watersports. The sea here is also shallow, so this is a good beach for families with children and the northerly breeze can keep the east-facing beach a little cooler in the summer.
A small outcrop of rock marks the western end of Megali Ammos beach and the eastern end of Vassilias beach. Those looking to escape the crowds will walk around the rocks and head east.
