An emerald island off the coast of Mount Athos, Ammouliani is a paradisiacal getaway. With powder-white beaches, turquoise waters and lush greenery, this stretch of land is a joy for beach lovers and snorkellers. Hikers too will love the walking routes and panoramic views through the island's rolling hills.

Bejewelled with mighty stalagmites and stalactites, the Petralona Caves once sheltered our ancient human ancestors. Today, you can explore the impressive network of caves and wander around the adjacent Anthropological Museum. Housed in the museum, you'll find fossilised animals and the Petralona skull, one of the oldest human remains, dating back hundreds of thousands of years.

Cloaked in dense forests with steep rock faces, Mount Athos rises high above the sea. The dramatic sight is enhanced by the 20 imposing monasteries that rise from the forests and dangle cautiously on the edge of cliffs. Unsurprisingly, the area is a UNESCO World Heritage Site, and a cruise to Mount Athos promises to be filled with picture-perfect moments.

With so many to choose from, it's hard to narrow down which beaches you should go to, but Possidi Beach and Karidi Beach are two of the finest in Halkidiki. On the Kassandra peninsula, the white sands of the Possidi cape stretch out into lapis waters, and on Sithonia, Karidi Beach has the softest sand and clearest waters of Halkidiki.
