A cruise to remember
Have you ever wanted to explore Egypt, the land of endless sun and ancient history? Why not do so on a cruise? Consider the Egyptian Magic cruise…

1__ There’s always something to do on the ship. A whole floor of basketball and tennis courts keeps exercise lovers happy. There’s a modern gym and two large swimming pools too.

2__ In the evening, the fun continues late into the night! The ship has got a cinema, a small theatre, and a disco with live music. Watch the latest films, a play, or dance the night away!

3__ For those who want a more relaxing holiday, there’s a beauty salon and spa on the 4th deck. Lie down, relax, and enjoy a back or foot massage from our top beauty professionals.

4__ Our first stop is Port Said. From here we travel to Cairo, to visit Egypt’s most famous monuments – the pyramids. The pyramids are over 4500 years old. Seeing them is an incredible experience.

5__ Before we leave Safaga, there is time to visit a busy local market. Egypt has always been famous for gold, and here is a great place to buy some beautiful gold jewellery. You can also buy lovely silver dishes. They make great souvenirs!

6__ The Egyptian Magic cruise ship has a fantastic variety of facilities available. For example, there is not one, but five restaurants. Have lunch in our top-quality restaurant or enjoy a snack at one of our cafes. The choice is yours!

7__ Our last stop is the seaside city of Sharm El Sheikh. With its warm blue sea and bright coral reefs, this is a great place for scuba diving. Dive down into a sea world more exotic and colourful than you could possibly imagine!

8__ The next stop is Safaga. Here it’s time for a desert adventure. Spend a day riding a quad bike across the golden sands of Egyptian desert. Stop for tea with a Bedouin tribe before you speed back across the dunes!
