Start with a traditional Algerian breakfast (fresh bread, lablabi/chickpea stew or msemen and mint tea) in a small café inside the Casbah to soak up local atmosphere.
See Algerian and North African paintings and artifacts in one of the country's major museums; good context for local art and history (typically open ~9:00–16:00, closed Monday — verify on visit).
Enjoy a multi-course Algerian dinner (couscous, tajine, sweets) at a reputable local restaurant in Casbah or Hydra; reservations recommended on busy nights.
Domestic flight to Constantine is fastest (~1h15m flight). Factor 1.5–2h for airport transfer and check-in from central Algiers (Houari Boumediene Airport).
Short drive (~30–45 min) to the Tiddis site to see Roman ruins and mosaics; site hours typically ~9:00–16:00 and it’s an open-air visit so dress for weather.
Options: 1) Fly Constantine→Oran (direct flights limited; often via Algiers) ~ total travel time 3–5h including connections; 2) Train/bus is long (8–12h) and usually requires change in Algiers; 3) Private car hire (long drive ~7–9h, scenic but tiring).
Most efficient is to fly Constantine→Algiers then Algiers→Oran same day; allow minimum 2–3h between flights for transfers. Expect total door-to-door 4–6 hours.
