Bus: During the day, buses are mostly used to connect Amsterdam to the greater metropolitan area. While locals use them on their daily commute, visitors are likely to use them even more so when venturing away from the city center to visit one of the Netherlands’ surrounding beach towns, gardens, or historic villages.
Buses are especially handy after 12:15 am when the metro and trams stop running. Night buses depart from each of their stops about every 30 minutes from 12:30 am to 7:00 am. Many operate to and from Central Station, with connections all around Amsterdam. Since there are fewer transportation options after dark, night routes are often longer than those in the daytime, so expect lengthier trip times.
