My husband and I will be travelling to Switzerland in late May and wondered if it is worthwhile to go to the Berner Oberland region in late May or if weather conditions make it not worth our while and we should see other parts of Switzerland instead. We would like to do some of the more mild/moderate hikes in the area.
I cannot give you first-hand info, but I think there have been similar questions on this forum in the past. Have you tried the search function at the top of the page? Might be some useful info there.
Berner Oberland is outstanding in late May. Great weather, not as crowded, fresh flowers.
Its a little too early for some of the better hikes-still covered by snow
and that was mid June-best time is beginning later in June. It's a magical
area of Switzerland with spectacular scenery.
I have stayed in Mürren in mid to late May very happily. Some of the higher trails may have been closed, but that didn't affect me. I'm a walker, not really a hiker....
It is true that every year the weather is different and we have no idea at this point what this winter will bring.
Ask locally before heading out into any obstructed trails.
I will be in Murren myself from 22 - 26 May and then one night in Lucerne. I follow an individual that lives in Murren on his Twitter account and this past May during the last week it was sunshine and flowers in bloom. In 2017 there was snow on the ground on 23 May, but all melted away and sunshine by 26 May. Lets hope for good weather, all I know is I will be there and not here.
