For a spin out along the coast, take advantage of BiCas, Cascais' free bike-hire scheme. The well-worn bikes are available from 8am to 7pm daily at various points around town, including Largo da Estação near the train station. Demand is naturally high, so arrive early and bring some form of ID. There’s a bicycle path that runs the entire 9km stretch from Cascais to Guincho. A shorter route is along the attractive seafront promenade to Estoril, 2km east.
