A more sustainable trip begins before you pack your bag. Planning with intention helps save resources, avoid unnecessary journeys and experience Cascais at a slower pace.
✓ Choose when to travel — If you can, visit outside peak periods. You will find a calmer pace and help spread the benefits of tourism throughout the year.
✓ Stay longer — Trade rushing for discovery. Longer stays support slow tourism, reduce repeated journeys and create a more genuine connection with the place.
✓ Prefer direct connections — When flying is necessary, choose direct flights. For suitable routes, consider the train or other forms of public transport.
✓ Plan by area — Group nearby beaches, museums, neighbourhoods and experiences on the same day. Fewer kilometres mean more time to enjoy.
✓ Travel light — Pack only what you need. Less weight makes travel easier and can help reduce fuel consumption in transport.
✓ Choose responsible operators — Look for companies that clearly explain how they reduce environmental impacts and support the local community.
✓ Pack reusable essentials — A bottle, shopping bag, small lunch box and solid or refillable toiletries help avoid many single-use items.
✓ Use digital documents — Tickets, bookings, maps and passes on your phone reduce paper use — but keep an offline copy of anything essential.
