Belfast to Paris (Roissy-en-France, Val-d'Oise) (BFS–CDG) — Airlines, Schedules & Connections

British passport holders enter France visa-free for up to 90 days in any 180-day rolling period under Schengen rules. No fee, no advance application. Passport must be valid for at least 3 months beyond the planned departure date with at least two blank pages. UK passports are stamped on entry and exit since Brexit. ID cards are no longer accepted for UK nationals.

No supporting documents are mandatory, but border officers can ask for proof of accommodation, onward travel, and sufficient funds (EUR 65 per day if staying in a hotel, EUR 32.50 per day if staying with a host, per the French consular tariff). The 90-day limit is shared across all 29 Schengen countries. French overseas territories (Martinique, Guadeloupe, Reunion, French Guiana, Mayotte) have separate entry conditions. ETIAS pre-travel authorization (EUR 7, valid 3 years) is expected to become mandatory in late 2026.

Direct flights from London to Paris run about 1 hour 15 minutes, with Eurostar at 2 hours 15 minutes city center to city center. Budget carriers serve dozens of French airports from UK regionals. France uses the euro. No vaccination requirements. UK driving licenses are valid for short visits. The Eurostar and Le Shuttle (car train) from Folkestone clear both UK and French immigration at the UK terminal before departure, so passport checks happen on the British side.

RER B to central Paris (Gare du Nord 25 min, Châtelet 30 min) costs €11.80. Take the free CDGVAL train from T1 or T3 to the RER station at T2 first. Heavy luggage is awkward on this line during rush hour; some platforms have no escalators.Fixed taxis: €55 to Right Bank, €65 to Left Bank. Ride-hail (Uber) costs €40–65. Le Bus Direct coaches run to Montparnasse, Opéra, and the Eiffel Tower (€17, 45–70 min). Connecting to Gare de Lyon or Massy for TGV services is possible via RER B (Denfert-Rochereau transfer).

Temperate oceanic climate. Summers are warm (20–27°C) and mostly dry with occasional thunderstorm delays. Winters are cold and overcast (2–8°C) with frequent rain and periodic frost. Snow is rare but CDG briefly closes when it falls on an unprepared system. Fog is the primary winter flight disruption, particularly November through January.

Spring is mild and wet. Autumn is the most unpredictable season weather-wise. CDG is a major hub. Even moderate weather cascades across European connections. Pack a mid-weight jacket year-round. Summers are rarely hot enough for short sleeves in the evenings.
