Cascais relies mainly on the CP Linha de Cascais commuter train (40 minutes to Lisbon Cais do Sodré, twice an hour), the Carris Metropolitana bus network and Bolt/Uber rides, and all three are friendly to dogs and cats under reasonable conditions. The CP rule of thumb: small pets in a carrier travel free, larger dogs need a short leash plus muzzle and a current vaccination booklet.

Frequently Asked Questions

Do I need a ticket for my dog on the CP Cascais Line?

No. Pets in a carrier ride free, and larger leashed dogs ride free as long as you have the vaccination booklet, municipal licence and the dog is muzzled. Only the eight "dangerous breed" categories are forbidden.

Can I bring my dog on the bus to Sintra?

Yes for any pet in a closed carrier on the 403 line. Medium dogs on a short leash are usually accepted at the driver's discretion outside peak summer weekends, ask before boarding.
