Biking in Amsterdam is a great way to get away from the crowded city and see the countryside.
Here is a quick 3-4 hour bike ride that won't be too tiring for most people:
1. Start at Amsterdam Centraal Station
2. Rent a bike at Mac Bike rentals or any bike rental place of your choice. Mac Bike is practical because it is literally right outside Centraal Station.
2. Take the Buiksloterweg ferry or the IJplein ferry behind the Centraal Station (Both are free). You can walk your bikes inside or ride your bikes around the station to get to the dock.
3. Follow the Google Map route to Durgerdam, Holysloot, Ransdorp and Zunderdorp.
