This exclave was in the spotlight in 2005 together with Melilla because hundreds of people were trying to climb above the border fence. Ceuta being part of Spain and therefore a safe haven for Africans made it a prime target for migrants. Today the border is heavily protected by the Guardia Civil. The European Union invested a lot of money to make illegal immigration more difficult.
Ceuta is easily accessible from Algeciras (Cadiz) by ferry. High speed ferry services run between Ceuta and mainland Spain every half hour as of summer 2007.
From land Ceuta is only accessible from Morocco. If arriving by bus, you may have to take a bus to a nearby town and then a taxi to the border. For example, coming from the south, the closest an intercity bus will take you is to Fnideq, Morocco.
The increased border security may result in minor waiting time. This could be longer if you travel in summer when the main holiday season in Spain and France starts and lots of families return to their homes in Morocco. Note that there seems to be separate lines for Moroccans and foreigners at many border crossings, ports, and security checks. If you find yourself stuck in an extremely slow moving line and do not look Moroccan, try getting noticed by an officer. You may find yourself ushered past the line and processed very quickly.
You will need a passport to cross the border with Morocco in either direction and official ID to book passage between Ceuta and mainland Spain. Rules for immigration are the same as for Spain.
There is just an heliport where [http://www.helisureste.com/ Heli sur Este] operates to daily connections between Ceuta and Malaga.
Ceuta is a tiny city. Best way is by bike or on foot. There are taxis available. Make sure they use the meter or negotiate a price before you get in. There is a decent bus service with modern and spacious buses running around the city with stops at the border with Morocco. Look for a bus marked "Frontera".
Ceuta is a free port, this means there are few or no taxes on goods. You will see that the economy of this city focus on people transiting to/from Morocco and one-day shopping tourists.
Ceuta is a great city to go out. There are several pubs and clubs and a great tapas route.
