🐾 Dogs in a hand-held carrier travel free on all NS trains. Larger dogs need a Dagkaart Hond (Day Pass for Dogs, €3.30, unlimited NS travel that day) and must be on a leash with a muzzle available in case of complaint. Intercity to Amsterdam Centraal 35 min, to Den Haag Centraal 12 min, to Rotterdam Centraal 25 min, to Schiphol 17 min.
💡 Buy the Dagkaart Hond at any yellow NS machine on the Leiden Centraal concourse before boarding; one ticket covers all NS travel that day, including the side trips to Den Haag, Rotterdam and Haarlem.
