The neighbouring island of Skopelos is only a 10 minute ride away on the hydrofoil. Skopelos is a beautiful island and has an attractive town with many traditional buildings. I have been wanting to paint there for some time and finally did so this winter. The church of St John at Kastri (featured in the Mama Mia Film) is definitely worth a visit; if staying on Skiathos it can make a very nice day trip.
