The town is small enough to explore entirely by foot. To get a feeling for the life it's best to stroll around on foot. Uphill, beyond the town centre there are numerous narrow cobbled streets to explore with interesting architecture, plants and animals to see.
By bike
Riding a bicycle in Cascais is one of the "must do" things. From the beach you can venture further up the hill towards the westernmost point of continental Europe mainland and even Sintra using the nice roads while crossing the heart of this incredible nature reserve so close to the capital city of Lisbon
Basic bicycles are available to rent for free providing you have ID and your accommodation address through the municipal council's BiCas scheme. Bicycles are available from several locations around the town. The tourist office will have further information. This bikes are heavily misused by locals, students, and budget minded visitors and often are not available when needed, when available most times not always in the best safety and enjoyable conditions thus the common breakdowns.
