I need suggestions for the best guide books on hiking in Switzerland. We will be there in August 2020.
I don't know about the books, but if you want to see what's in the Berner Oberland/Jungfrau area, click on my name and you'll find a link to our favorite hikes in the area.
Not a guide, but where to get official topo maps with paths marked.
Go here: https://map.veloland.ch/
Then click on "Hiking in Switzerland", then zoom to your desired area.
Hiking paths are shown in green. Dashed lines ( - - -) are mountain paths, experienced walkers only. Solid lines (____) are normal paths.
You can print out maps (convert to PDF) at your desired scale (1:50 000 or 1:25 000), ten either print he PDF to paper, or out on your phone.
There are many hikes depicted online. Good search function here in MySwissAlps and I often find ideas by Googling “hikes in XXX.”
The Cicerone Guides are my husband and my go to, they seem to cover everywhere in Europe. Very detailed.
I have found these two books very helpful for planning purposes:
Swiss Bernese Oberland
Even better is Olle, who rents a few rooms in his house in Gimmelwald. He knows all the best trails in the area, even ones not appearing in these guides. And he knows the current trail conditions. He always gives me the current info when I arrive. Be sure to ask your "Olle" when you arrive since locals who hike or cater to hikers are the most knowledgable source.
