When choosing a route, make sure it corresponds to your experience and physical fitness level. Check the weather forecast before you set off. The weather can change surprisingly quickly in the mountains. Always take appropriate equipment with you (e.g. rain protection).
Check whether the cabins and snack stations you intend to visit along the way are open. Inform someone before you set off of your chosen route and when you plan to return.
