The most convenient way to travel between Lisbon and Cascais is by train. Trains depart frequently (every 20 minutes) from Cais do Sodre station in Lisbon and take approximately 40 minutes to reach Cascais. The other option is by renting a car. Driving offers a scenic route along the coast (A5 motorway) and takes about 35 minutes depending on traffic. However, parking in Cascais can be challenging, especially during peak season. It's much better to park at the parking garage.

Catching the train from Lisbon to Cascais is easy, but there are a few things to keep in mind to avoid long lines. The trains leave every 20 minutes from Cais do Sodré station in central Lisbon, and the journey itself is a beautiful 40-minute ride along the water.

Here's where things can get a bit crowded: buying tickets at the station can take 20-30 minutes due to long queues. To skip the wait altogether, consider getting a Lisboa Card. This card gives you free travel on public transportation, including the train to Cascais, plus free or discounted entry to many attractions in Lisbon.

There are no return tickets, so you'll need to buy two single tickets - one for each way. There's also a 24-hour ticket for €6, but this isn't a good deal unless you plan on taking several train trips throughout the day.
