Oeiras
Visit Oeiras in a half‑day from Lisbon: 3‑4 h for the aquarium, Poets’ Park and a seaside lunch; no overnight needed.
Oeiras is a coastal municipality in Greater Lisbon, reachable in 15‑20 min by train from central Lisbon. Its main attractions – the Vasco da Gama Aquarium, Parque dos Poetas and historic palaces – fit comfortably into a half‑day, making it a day‑trip rather than a base.

Rules in force · 8Non-EU visitors get 90 days in any rolling 180-day window…
- Europe ↗Non-EU visitors get 90 days in any rolling 180-day window, counted across all 29 Schengen states together — not per country; the Entry/Exit System now logs each crossing, so an overstay is detected automatically.
- Europe ↗On the first Schengen entry since EES began, non-EU travellers give four fingerprints and a face photo at the border instead of a passport stamp; there is nothing to apply for or pay in advance.
- Iberia ↗Plan meals on the Iberian clock: Spanish kitchens serve lunch from about 13:30–14:00 and dinner from 20:30–21:00; Portugal eats an hour or so earlier. Early evenings are for tapas or petiscos, not full meals.
- Iberia ↗Inland Spain and Portugal (Seville, Córdoba, Madrid, the Alentejo) pass 40 °C in heatwaves from late June to August: sightsee before 11:00 and after 18:00, and keep July–August for the coasts and the green north.
- Iberia ↗Andorra and Gibraltar have their own border and customs rules and are reached only through Spain (or France for Andorra); read their pages before adding them, especially if you hold a limited Schengen visa.
- Portugal ↗Portugal is in the Schengen area. Check the entry rules for your passport on official sources; the EU's Entry/Exit System registers non-EU visitors at the first Schengen border, and further pre-travel authorisation rules are being introduced.
- Portugal ↗Alfa Pendular and Intercidades trains assign seats: book Lisbon–Porto ahead in summer and on holiday weekends.
- Portugal ↗Many motorways, including the Algarve's A22, use electronic tolls only: ask the hire company for a transponder before you drive off.
Entry rules depend on your passport. Full visa guide
