Sani is the first place on the west coast looking from Thessaloniki (70km away). It's primarily known for famous hotel complex Sani Resort, for many years the largest complex in the entire Greece. This luxurious complex consists of several hotels and buildings along the beautiful beach. Within the hotel there's also a fantastically landscaped garden, a large marina for luxury yachts, church...
Sani Beach is one of the most beautiful Kassandra. The sea is wonderfully turquoise and the sand is whitish, fine and soft like flour. Shoal is long, so this beach is paradise for families with children.
Unfortunately, most of the beach is available only to hotel guests. The only part of the beach that can be used by other visitors is in front of café Anemos. There is also the only free parking, but in the season you should come quite early as it is from 9:00 already overbooked. Parking belonging to the hotel costs 20e per day. Often during the season, the only free parking space is 400-500m away from the beach.
Out of season beach loungers and umbrellas at café Anemos are not charged, but obtained with drinks, while later daily rent for wooden deckchair is 5e and for metal is 3e. Anemos has great music, and the atmosphere is always relaxed.
Within the complex there's a large number of taverns and restaurants that are open to all visitors, as well as a supermarket. Entrance to the complex is paid only in high season, but because the hotel policy changes frequently, you should check before visiting.
In general, Sani is a resort reserved for the rich people. The beach is beautiful, and it's a shame that's mostly available only to hotel guests. The open part is much smaller and quite full, therefor often overcrowded. In this section there's also a little space for visitors with their own equipment.
To the left from café Anemos, as looking toward the sea, there's a camping.
From the beach you can enjoy a wonderful sunset.
In the marina you can rent a private yacht or a boat with a captain and visit some of the most beautiful cities on Kassandra, Athos and Sithonia, and that on this trip almost certainly encounter dolphins.
