US citizens need a passport valid for their stay, a return or onward ticket, and proof of accommodation if asked at the border. No visa is required for stays up to 90 days. From late 2026, US travelers will also need to apply online for ETIAS authorization before departure.

A Schengen short-stay visa is typically issued for multiple entries within its validity period, allowing stays of up to 90 days in any 180-day period. Once launched, ETIAS will be valid for 3 years (or until your passport expires, whichever comes first), also allowing up to 90 days per 180-day period. Entry itself is always decided by the border officer on arrival.

If your flight to Portugal is cancelled, EU Regulation 261/2004 entitles you to a full refund or free rebooking, plus assistance such as meals and accommodation if the delay is lengthy, provided you're flying with an EU carrier or departing from an EU airport. Contact your airline immediately and keep all receipts for costs you may be able to claim back. Triwize's 24/7 support team can help with rebooking and claims for bookings made through our platform.

Don't assume everyone speaks Spanish — Portuguese is a distinct language, and locals appreciate a few basic phrases. Don't skip validating bus or metro tickets before boarding, as inspectors do check. Avoid wearing beachwear away from the coast in cities like Lisbon and Porto, and don't rent a car if you're only visiting historic centers, since streets are narrow and parking is limited. Keep valuables secure on crowded trams (like Lisbon's Tram 28) and in busy tourist areas, where pickpocketing is the most common issue.
