Vassilias is a long and narrow sand and rock beach that extends from the western end of Megali Ammos beach, about four kilometres from Skiathos Town and stretching for a considerable distance.
The eastern half of the beach, nearest to Megali Ammos, has the better strip of sand and there is a small cantina here that opens up in the summer months.
A small rock outcrop marks the divide between the two beaches and the ranks of sunbeds disappear the further down the beach you go.
There are still sunbeds for hire and plenty of natural shade from the trees at the back of the beach. Further along the sand narrows and the cliff rises until the end of the beach where there is a taverna and watersports club, with hotels dotted in the hills behind.
The steep hillside and that helps protect Vassilias from the northerly winds and it's a place to head for to avoid the crowds that can gather on Megali Ammos.
You can reach the western end of the Vassilia beach down very steep concrete track that snakes down the hillside with a shady taverna halfway down - most welcome on the way up.
This end of Vassilias is hardly a beach at all, just piles of rocks hugging the steep cliffs with the odd scrap of sand between.
But the western shore offers a pleasantly remote spot only a short distance from some of Skiathos' most crowded beaches. Bus stops 7 and 8 are the closest to Vassilias beach.
