We are considering driving from Lauterbrunnen to Appenzell (and then on to Fussen) on May 1st. We are stopping in (near?) Appenzell to visit Berggasthaus Aescher-Wildkirchli before continuing on to our hotel just outside of Fussen (I am aware this will be a very long day). I have read many of the posts and precautions regarding driving in Switzerland. However, time-wise it seems to be the best option for our destinations. So this is my question: with the understanding that weather may be unpredictable in April/early May, should we expect to encounter any particularly snowy mountain roads between these points? We are shooting for the shortest route for time's sake, if that helps.
Any insight is appreciated. Thanks a bunch!
TLDR: any potentially extra snowy mountain roads between Lauterbrunnen and Appenzell early May?
