Train to Weesp or Naarden-Bussum and Bus 110

Muiden and Naarden have no station of their own. For the castle, get off at Weesp and take bus 110 to Muiden Centrum; for the fortress, get off at Naarden-Bussum and take the same 110 to the Westwalstraat stop, a hundred metres from the Vestingmuseum, in about 10 minutes. The 110 also links Muiden and Naarden, so you can do both on the same day. On spring-to-autumn weekends, the MuiderslotExpress 510 runs from the Muiden P+R to the castle for €1.
