Algiers is the capital and largest city of Algeria, and the second largest city in the Maghreb (after Casablanca), with a population of 3,354,000 within the city metropolitan area. Algiers is situated on the west side of a bay of the Mediterranean Sea. The modern part of the city is built on the level ground by the seashore; the old part, the ancient city of the deys, climbs the steep hill behind the modern town and is crowned by the casbah or citadel, 400 ft (122 m) above the sea.
Houari Boumediene Airport (ICAO: DAAG, IATA: ALG)  is located 20 km (12 mi) southeast of Algiers: the airport is named after former Algerian president Houari Boumediene.
The airport is the home base of the flag-carrier Air Algerie.
Air Algerie serves the most important Algerian cities (such as Oran, Annabaq, Tammanrasset, Skikda, Tlemcen, Constantine) several times daily. There also many connections to African capitals such as Bamako, Cairo, Abidjan, Dakar, Tunis, and Ouagadougo.

Bus. The bus operates every 30 min in the daytime to the centre for and costs 25 dinar paid on the bus.
Algiers Central Train Station is located near the city centre. The station offers regular services to major Algerian cities such as Oran, Annaba, and Constantine. SNTF (the national Algerian Train company) has made big improvements during the last years: new air-conditioned trains have been purchased and new routes launched.
Being the capital of the country most, if not all major roadways in Algeria begin and end in Algiers. So getting into Algiers is quite easy. However, the infrastructure of Algerian roadways is not highly regarded so arriving by road might not be the most desirable option. There are a number of road projects around the country that are aimed at improving the infrastructure, most notably the East-West highway running from Annaba in the east to Oran in the west, of course coming through Algiers.
La Gare Routiere, Algiers's central bus terminus, located in the commune of Hussein Dey (about 7-10 min drive from downtown), offers a plethora of bus services to most major Algerian cities and towns. It is a very cheap and efficient way to get to/from a pair of Algerian cities. Most of the coaches used are modern and air-conditioned so the rides are, more often than not, comfortable. However, there are a few old coaches still in service, so try to avoid those, for the ride won't be as pleasant.
For long distances as Algiers-Tammanrasset or Algiers-Annaba travelling by plane is recommend due the long duration.
They are regular ferry services to Algiers from Marseille, Nice, Palermo, Alicante .
Algiers Public Transportation is lacking but the city is going to make improvements with the opening of the long-delayed first Metro line: there are buses opereating within the city center and to the suburbs.
