Anvers is a metro station between the 9th and 18th arrondissements of Paris and the gateway to the Montmartre hill. You can buy metro tickets in the station, and a pharmacy sits directly in front of the exit with Sacré-Cœur visible from there. The walk from the exit up the hill is not long, and the surrounding streets have street performances and shops selling souvenirs, snacks and chocolate. The area draws crowds, so keep track of your belongings.
