The region of Halkidiki lies southeast from Thessaloniki. It is known for its jutting peninsulas, Mediterranean forests and sandy beaches in warm, sheltered bays. The region is often described as having three 'legs', the Kassandra, Sithonia and Athos peninsulas. Kassandra, the westernmost peninsula, is the most developed, offering modern resorts and nightclubs. Sithonia, also known as Longos, offers over a 100 beaches, cute villages and is a popular destination for families. Athos is an important centre of the Eastern Orthodox church. Its main point of interest, Mount Athos, is home to 20 monasteries.

Aristotelous Square is the most impressive square in Thessaloniki. It features buildings with monumental architecture inspired by European and colonial models, cafes, shops and restaurants. It is the focal point in big celebrations, such as the coming of the New Year, and is the de facto meeting place during the day. The history of Aristotelous Square began with the Great Fire of 1917 that destroyed two thirds of the city. The French architect Ernest Hébrard designed Aristotelous Square to serve as an end of a monumental axis for Thessaloniki that would stretch from the seafront to Dikastirion Square and the Roman Forum. The final design, built in the 1950s, is a lot more stripped down than Hébrard's original proposal, but still has significant architectural value.

While there's plenty to so in Charlotte Amalie on land, it would be a great loss not to explore the underwater wonders of the U.S. Virgin Islands. The easiest thing to do is rent a snorkel and explore the shallow waters by the beach, but you should definitely consider trying something more advanced at least once. Snorkelling is the cheapest choice. Add some diving equipment to go deeper and see more. Some tours now offer Sea Trek helmets — a modern take on the diving helmet. No matter your choice of equipment, do explore the coral reefs that are home to tropical fish such as snapper, hamlets, parrot fish, sturgeon, squirrel fish and majestic sea turtles.
