Ceuta is very small — the entire territory covers about 18 square kilometres — and the city centre is compact enough to cover on foot in a single morning. The ferry terminal, the Royal Walls, the cathedral, and the Parque Marítimo are all within a 20-minute walk of each other. Monte Hacho, at the eastern tip of the peninsula, is the main destination that requires a bit more effort: about 45 minutes on foot from the city centre, or a short taxi ride.
Buses — A small municipal network covers the city and extends to the border crossing at El Tarajal. Useful for reaching the outer residential areas and the border, less necessary for the main sights.
Taxis — Available and inexpensive. Fares are metered and the city is small enough that no journey should be expensive.
On foot — The best way to explore the old town, the walls, and the waterfront promenade. The terrain is mostly flat except for the climb to Monte Hacho.
Driving — Not worth it for the city centre, where streets are narrow and parking difficult. If you arrive by car on the ferry, leave it near the port and walk.
