To reach the beautiful coastal town of Cascais from Lisbon in 2026, you must head to the Cais do Sodré train station. This station serves as a major transportation hub and is the starting point for the "Linha de Cascais" urban railway. Cais do Sodré is located on the edge of the historic center and is easily accessible via the Green Line of the Lisbon Metro. Once at the station, you can purchase a ticket for approximately €2.45 (or use your rechargeable "Navegante" card) at the ticket office or automated machines. The train journey is incredibly scenic, hugging the Tagus River and the Atlantic coastline for the entire 33-to-40-minute trip. Trains typically depart every 20 minutes, running from early morning until 1:30 AM. Along the way, the train passes through the historic Belem district and the surfers' paradise of Carcavelos before terminating in the heart of Cascais. The Cascais station itself is perfectly positioned in the town center, making the beaches, restaurants, and pedestrian zones just a short walk away upon arrival, making this one of the most convenient and popular day trips from the Portuguese capital.
