The number of days one should spend in Geneva greatly depends on individual travel plans and interests. To fully experience the charm and attractions of the city itself, a minimum of two or three days would be ideal. This would allow time for exploring iconic landmarks like Jet d'Eau, St. Pierre Cathedral, and Old Town's historic streets along with visiting museums such as Maison Tavel or the International Red Cross Museum. Additionally, spending an extra day or two would enable travelers to take day trips to nearby attractions like Mont Blanc or Chamonix in France, or even explore other Swiss towns like Lausanne or Montreux which are easily accessible from Geneva by train or boat.
