Most travellers come to Algeciras for its numerous ferry connections to Morocco and don't spend more than a few hours in the city. A shame, given the town's quiet charm.
The north-south coastal road, Avenida de la Marina, is Algeciras's main artery. The tourist information office (Calle Cervantes), is well signed from this road.
Algeciras is on the Western side of Bahia de Gibraltar(Bay Of Gibraltar) virtually opposite Gibraltar. Roughly speaking it is orientated North to South. The Avenida Virgen del Carmen is the main road that runs along the water front. The ferry port is about midway along the Abenida del Carmen - it can't really be missed as dozen of signs are pointing in its direction and there is constant ferry traffic in and out of the port. There is also an elevated heliport right in front of the ferry port.
The main shopping streets, together with the town square and central market, are set back behind the Avenida Virgen del Carmen and are mainly pedestrianised. There is a wide range of shops here, from local food shops and boutiques to the main brands.
The bus and railway stations are close together, about 300m west (and slightly to the south) of the ferry port in the main town.
The Algeciras train station is located 300 metres west of the port entrance. Just walk outside the station and straight down Calle Cervantes (the street in front of you) until you reach the Avenida de la Marina. You will see signs from here to the port. From Algeciras there are daily train connections to Madrid. Three a day on the picturesque route to Ronda and Granada.
The central bus station is just up the road from the tourist office, heading away from the port.
The ferry terminal is the heart of Algeciras and is well-signed from most roads in the city. Services from the following destinations arrive at the port:
If you are headed for the bus station, you have to leave the port and walk about 7 minutes up the hill (opposite of the ocean).
See the beautiful Plaza Alta and the nearby San Isidro district.
Getares beach and Rinconcillo beach.
You'll find plenty of cheap bars, cafes and restaurants along the Avenida de la Marina, Calle Alfonso Once and around Plaza Alta. They stay open long into the night. Often not closing until the early hours.
If you're stuck in Algeciras after the last ferry or bus has left town, you'll find plenty of budget accommodation options in the neigbourhood around Avenida de la Marina. In the busy season, you can expect to get a double for €18 a night.
The Hotel AC on the eastern edge of the city centre is a fantastic brand new hotel with very friendly staff. Rates can be as low as 65 Euros per night.
There are a couple of basic hotels opposite the ferry port entrance:
Avoid going to neighbourhoods like Saladillo, Bajadilla or La Piñera. Even though it's full of friendly Romani people, you might get in trouble if you look foreign.
