When to visit
The best time to visit Interlaken & Bernese Oberland in general is in summer, which is July – September. However, it is very busy during these times. So, shoulder seasons are a good alternative, especially October – November, because the snow hasn't come yet and the weather is usually quite sunny.
During winter, some of the outdoor activities will not be possible, like hiking, however, all the gondolas and trains are running, and the views are still the same, just a bit whiter! Of course, you can also try other winter sports like skiing, snow shoeing, tobogganing, winter walking and ice skating.
