The best time of year to visit Norway depends on what kind of activities and experiences you are looking for. If you are looking for outdoor activities such as hiking, fishing, and skiing, then the summer and fall are great times to go as the days are longer and the weather is usually milder. If you are looking for activities such as sightseeing, cultural events, and festivities, then the winter and spring are great times to visit as the landscape is covered in snow, the ski slopes are open, and the Christmas and Easter celebrations are very festive.
