National Cycling Day, or Landelijke Fietsdag, is observed in the Netherlands every second Saturday of May. This informal observance celebrates the country's rich cycling culture, where every Dutch person owns at least two bicycles. On this day, many cyclists embark on day trips to enjoy the scenic landscapes and pleasant weather, often using online route planners to select their destinations. The event coincides with National Mills Day, providing an excellent opportunity for bike tours to visit various mills that open their doors to the public. With approximately 32,000 kilometers of dedicated cycle paths, cyclists in the Netherlands benefit from well-designed lanes, crossings, and traffic signals, making cycling a popular mode of transportation for both commuting and recreation.
