Hiking Trail Detailed Maps

https://map.geo.admin.ch has detailed topographic maps of the entire country, fully up to date. It is amazing.
If you need paper maps, you can find them locally, but they might ship abroad (look at the Swisstopo website for the catalogue, the 1:33,333 maps are perfect).
Maps are best combined with trail descriptions: https://myswitzerland.com has plenty.

By the way, there's no need to sign your posts with your email address; I would encourage you to edit your post & remove it - spammers run bots that "harvest" them.

Thanks. I will check your references. And, email deleted. Thanks for that as well.

Walking in Switzerland's Berner Oberland by Laurel and Richard Barton has 20 hikes in it but not with the detail you are looking for. However, they suggest: "The maps in the book provide an overview of the route but the linked maps at PlotaRoute.com will allow you to zoom in on sections and see specific features. You can also change the view from the Standard Street Map that is pictured in the book to other views such as Terrain or Satellite views. The elevation profile of the route is shown in the online version where you can adjust a time feature to suit your pace, get a weather forecast and more. Play with it!"

You might see if the hikes you are interested in appear on that website.

Janet thanks for the shout-out!

Dale, I use PlotaRoute to assess possible routes in cities and in rural locations, at home and abroad. It will give you an idea of the difficulty in terms of elevation gain or loss as well as distance. You can print a map to take along. AllTrails and Kamoot are good, too, although I think the posters there tend to overestimate what “easy” might be for many of us. “Easy” at 30 years of age is a lot different than easy when approaching 70 or if you have a disdain for extreme descents (like me!).

I also like this company’s map of the LauterbrunnenTal for planning, looking for options, and avoiding getting lost. You might need a magnifying glass, though. EditionMpa publishes dozens of detailed Swiss maps.

I have a couple of the 1:25000 topographic maps but I honestly cannot recall where I bought them. Probably in Switzerland, but this UK bookstore offers them online:

https://www.stanfords.co.uk/Switzerland-Swiss-Survey-25K-Topographic-Maps_SI00000370?wgu=5563_198311_16659327410302_9ca22f9f19&wgexpiry=1697468741&utm_campaign=webgains&utm_source=webgains&utm_medium=webgains

I will admit, however, that I rarely use them for planning hikes. I like to find a good description of the hike, whether in a guidebook or online, that gives the length, the elevation gain and loss, and some details regarding terrain and possible exposure or other hazards. Then we use the schematic paper maps from the local visitor center, together with the trail signage.
