Sani's hotels offer lots of activities to keep you busy during your stay, from sports academies and art classes on the Halkidiki beaches, to children's groups. There's even a Sani Resort app showing what's on around the resort that can be accessed via Wi-Fi in all public areas.
If you want to explore the beautiful Kassandra countryside, the opportunities are wide. There's a path opposite the entrance to the Porto Sani Village hotel, which leads to a wetland with two coastal lakes. Over 180 different species of birds can be seen here, from flamingos to herons.
You could cycle along the country roads around Sani or take a long stroll to the ruins of a Roman villa. This two-hour walk through the forest rewards you with a clifftop view from the villa, passing turtle ponds along the way.
During July and August, the Sani Festival brings together some of the most renowned jazz, classical and folk musicians from Greece and beyond. With the main stage set in an open-air amphitheatre on Sani Hill, you can listen to top-quality music in beautiful surroundings by the castle ruins.
The festivities don't end after the performances, with the audience at the stage on the beach spilling out into the beach bars and after-parties carrying on at the marina.
Out and about
At Sani, you're a 90-minute drive from Greece's second city of Thessaloniki, well worth a visit for its culture and shopping opportunities. Brimming with Byzantine architecture, the huge Agios Dimitrios 5th century church holds an underground crypt tour. Or you could swing by the market as well as two shopping centres on Tsimiski Street.
For a more homespun shopping experience, the biggest market in the region is 30-minutes' drive away in Nea Moudania, selling embroidered linens and leather handbags. Just beyond here is Petralona cave, which will intrigue history lovers as it is where some of the first signs of European civilisation were found.
Stylish marina takes pride of place
The marina is the hub of the resort of Sani, with expensive yachts in the water and exclusive shops in the piazza. By day you can peruse the Gucci or Dolce & Gabbana stores and come evening there is plenty of choice at the gourmet restaurants and classy bars.
You might think that all that fancy food will burn a hole in your pocket, but by using the Dine Around scheme run by the resort hotels, you can eat well at a decent price. As well as Greek, Italian and modern Mediterranean restaurants you can dine at sushi places and Indian tandooris. There are also some great French-style patisseries at the marina if you fancy a treat while strolling around.
The Halkidiki destination of Sani is also the place for cool cocktail and lounge bars, some of which play jazz and ambient music. Many are open until around 1am or, for all night parties, Kalithea is just 20 minutes away. You'll also find some chilled-out beach bars along the coast in Sani to lounge away the afternoons and evenings in.
