Like many other cities in Morocco, Marrakech is divided into two distinct parts - the Medina (or old city) and the new part with Hivernage and Gueliz. This combination of old and new creates a backdrop of interesting architecture and sights for all travellers.
To get a real feel for the city, you will want to head to Djemma El Fna. This is an exciting gathering of artists, musicians, and dancers that congregate in the middle of the old city. Heading to the markets, or the souks, is also a must see and a fun adventure when it comes to haggling over the prices. The Koutoubia Mosque towers over Djemma El Fna and is considered to be the Eiffel Tower of the city. You can also explore the Saadian Tombs with their beautiful tiles and decorations.
Flying into Marrakech is simple with the Marrakech-Menara Airport. Only 15 minutes from the city, many outlying airports fly to this airport. You can also take cars and trains into the city, if you like, though these will work better if you don't have a lot of luggage to carry with you. Getting around the city basically requires a good pair of walking shoes as all points of interest can be accessed by foot. If you need a rest, you can take one of the four main bus lines to help you get from one point to the next. When you're planning more of a romantic vacation, a caleche (horse drawn carriage) is a good way to travel.
Hot spots for tourists are the Riad Zolah and Riad Hayati, but when you want to get away from the crowds hostels like Heart of the Medina Backpackers Hostel will help you rest after a long day of exploring.
