Chefchaouen – or Chaouen, as it is often called by Moroccans – is a popular tourist destination because of its proximity to Tangier and the Spanish enclave of Ceuta.
Chefchaouen's blue walls are a popular subject of interest. There are several theories as to why the walls were painted blue. One popular theory is that the blue keeps mosquitos away, another is that Jews introduced the blue when they took refuge from Hitler in the 1930s. The blue is said to symbolize the sky and heaven, and serve as a reminder to lead a spiritual life. 
The beauty of Chefchaouen's mountainous surroundings are enhanced by the contrast of the brightly painted medina (old town). It is this beauty and the relaxed atmosphere of the town that makes Chefchaouen very attractive to visitors. 
The countryside around it has a reputation for being a prolific source of kief. The Chefchaouen region is one of the main producers of cannabis in Morocco. Hashish is subsequently sold all over town, but is mostly the domain of native Chaouenis. A nearby attraction is the Kef Toghobeit Cave, one of the deepest caves in Africa.
