Getting in

• Lisbon Humberto Delgado Airport: For central Cascais, skip a pre-booked private transfer unless you are a group with substantial luggage. Take the Metro Red Line from Aeroporto, change at Alameda for the Green Line to Cais do Sodré, then take the CP Cascais Line to Cascais. Allow roughly 85–100 minutes door to door and about €4–5 in transit fares, plus any reusable-card charge. A taxi/rideshare is usually 35–45 minutes in light traffic and roughly €35–45, but can be poor value solo.
• Cais do Sodré station, Lisbon: This is the useful Lisbon rail gateway: take a CP Cascais Line train direct to Cascais. The ride is about 40 minutes; Cascais station is at the edge of the historic centre and beaches. Do not confuse it with Oriente or Santa Apolónia—those are not on the Cascais Line.
• Aeródromo Municipal de Cascais: A niche option rather than a general international gateway: Sevenair serves it from Bragança (BGC), Portimão (PRM), Vila Real (VRL) and Viseu (VSE). It is relevant only if one of those domestic flights suits; Lisbon Airport is the practical arrival airport for almost everyone.
