For hiking in Switzerland, there are many useful websites.
The ones I use are:
map.search.ch/?pos=685376,202240&z=4& poi=bergbahn,haltestel le,zug
In that link, under points of Interst on the menu, I have turned on "Traffic" and seletec public transport stops.
2.- Switzerland Mobility - useful for altitude profiles, as long as your hike is in the index.
Search by town name. The maps are very detailed. I gave you a link to that before. The section on hikes is "wanderland.ch"
3.- The best and most complex map of all - Swisstopo
map.geo.admin.ch/?topic=ech&lang=en&bgLa yer=ch.swisstopo.pixel karte-farbe&layers=ch.bav.ha ltestellen-oev,ch.swisstopo.swiss tlm3d-wanderwege&layers_visi bility=false,true&X=20 4750.00&Y=679725.00&zo om=4
In that link I have turned on hiking trails.
Yellow are easy; red need boots and hiking staffs, and can be rocky; blue are technical climbing or otrehr exotic features best done with a guide.
The yellow/red/blur trails match the trail signs:
Altitudes are useful, as are topographic features.
The Swiss are a nation of hikers, and their definition of a level trail can include slopes up to plus or minus 20 degrees. ;-). Just kidding, but there are a lot of ups and downs.
